Human Impact On the Environment

The graph above shows the change in air temperature from 1860 to 2000. The rate at which the air temperature has increased has been constant because the change in air temperature is a straight line (line of best fit). This shows us that there is a linear relationship. The graph has a positive correlation because the line is going up and the temperature is increasing. As years go by the temperature rises with it. This is shown in the graph because in 1860 the temperature was -0.1�C whereas in 2000 the temperature was 0.7�C, this shows that there has been a increase of 0.8�C over the 140 years; this means that the surface air temperature has been gradually rising.

The graph has a curved line which means that the numbers don’t have a consistent rate of change and don’t follow a precise order. There is a link between the change in air temperature and the thickness of ice because as the temperature of surface air increases the thickness of ice in the arctic sea decreases. This is a linear relationship because as one increases the other decreases. An example for this would be in 1960 where the surface air temperature was 0.3�C and the thickness of ice in the Nansen Basin located in the Arctic Sea in the years 1958 to 1976 was 3.8 metres.

Whereas 40 years after in the year 2000 the temperature of surface air was 0.7, this shows that the surface air temperature has increased by 0.5�C. Alongside this change the thickness of ice had decreased to 2.2 metres in the years 1993 to 1997. There is a decrease of 1.6 metres in ice thickness over this time. These years were the closest to 2000 which is why they have been used although they aren’t 100% accurate they were the closest possible to 2000. This proves that as the years have passed the surface air temperature has increased while the thickness of ice has decreased and will carry on decreasing if surface air temperature decreases further.

Global Concentration of Carbon Dioxide in the atmosphere since 1870

The graph above also reflects a positive correlation because the line is slightly curved and is going up. The graph is showing the global concentration of carbon dioxide in the atmosphere. The graph is showing that the levels of carbon dioxide have increased in the atmosphere since 1880. In 1880 there were 290 parts per million of carbon dioxide in the atmosphere whereas in 2000 there were 370 parts per million concentration of carbon dioxide. There has been an increase of 80 parts per million concentration of carbon dioxide in the atmosphere. The line of best fit is a non-linear relationship with the points on the graph.

There is a link between graph 1 and 2. In graph 2 the results reflect that the levels of carbon dioxide have increased, so the link is that in graph 1 the surface air temperature has increased with increasing carbon dioxide concentration in the atmosphere. An example to reflect the link could be that in 1920 the global concentration was 300 parts per million. Whereas in the year 2000 the global concentration was 370 parts per million, this shows that in 80 years the concentration increased by 70 parts per million. Similarly in graph 1 the surface air temperature was 0�C in 1920 whereas in 2000 it was 0.7�C. The surface air temperature has increased by 0.7�C over the 80 years. Both global concentration of carbon dioxide and surface air temperature have increased from 1920 to 2000. This suggests that as global concentration of carbon dioxide increases the surface air temperature in the atmosphere also increases.

This is bad for the environment because carbon dioxide is one of the factors causing global warming. The cause of carbon dioxide is the burning of fossil fuels. There is a lot of carbon dioxide because people want a high standard of living and to do so they need a lot of energy to power everything they use. As technology has developed the carbon dioxide levels have increased. A major factor contributing to these levels is the use of cars and planes basically transport vehicles. In the UK there is double the amount of cars registered as there are people in the UK. Cars are constantly adding more carbon dioxide into the atmosphere. The more carbon dioxide the higher the surface air temperature and the more decrease in thickness of ice. These are the causes of global warming.

Thickness of Ice in Areas of the Arctic Sea

This graph shows the ice thickness in 6 locations within the arctic sea at 2 different times; from 1958-1976 and 1993-1997. It shows the ice thickness at the Chukchi Cap, Beaufort Sea, Canada Basin, North Pole, Nansen Basin and Eastern Arctic. The first turquoise bar for each location shows the ice thickness in 1958-1976 and the second blue bar shows the ice thickness in 1993-1997. By comparing the two bars for each location we can see that over the years the ice thickness has decreased in every location within the Arctic sea by almost half. This can be shown with an example; in 1958-1976, the ice thickness at the Beaufort Sea was 2.1, whereas in 1993-1997 the ice thickness decreased by 1 metre as it is at 1.1 after this period of time.

By looking at the Temperature variation of surface air temperature graph and this graph I can see there is a link because as surface air temperature increases the ice thickness decreases because it slowly melts because of the increase in surface air temperature. Because the earth is getting warmer, there is an increase in Surface air temperature all over the world meaning that the ice thickness in all of the locations within the Arctic Sea is decreasing. As the years go by the ice thickness is decreasing. Another example to prove this could be that at the Canada Basin in 1958-1976 the ice thickness was 3.5 metres; however several years later in 1993-1997 the ice thickness decreased to 2.1 metres which proves that the ice thickness is decreasing in all locations within the Arctic Sea.

There is a link between the global concentration of carbon dioxide and the thickness of ice, as the carbon dioxide increases the thickness of ice decreases. An example to show this could be that in 1940 the global concentration was at 305 parts per million and the thickness of ice in the North Pole was 2.1 metres in 1958-1976. However both had changed over the years. The carbon dioxide in the atmosphere in 1960 was 320, this shows that the global concentration increased by 15 parts per million, the ice thickness also decreased as the carbon dioxide levels increased, In the North pole the thickness of ice decreased by 1.3 metres because in 1993-1997 the thickness of ice in the North Pole was 2.4. This proves there is a link because as the global concentration of carbon dioxide increases the ice thickness decreases as the years go by.

The ice thickness is decreasing because there is more global concentration of carbon dioxide in the atmosphere which is causing the surface air temperature to increase which is causing the thickness of ice to decrease. There is a link between all three graphs. An example to show the link between the three graphs could be that in 1960 the global concentration of carbon dioxide in the atmosphere is 320 and the surface air temperature in 1960 was 0.3�c and the thickness of ice in the Canada Basin was 3.5 metres. However in 2000 the Global concentration of carbon dioxide was 370 parts per million and the surface air temperature in 2000 was 0.7�c. And the thickness of ice was 2.1 metres in 1993-1997. There is a link because as the carbon dioxide levels increase it makes the surface air temperature to increase making more ice melt which reduces the thickness of ice.

Global Warming

Global warming is when the earth’s atmospheres temperature increases or rises and it heats up. This happens because the rays from the sun are absorbed and trapped by the different layers in the earth’s atmosphere. Global warming happens when greenhouse gases such as carbon dioxide, water vapour, methane and nitrous oxide trap heat into the earth’s atmosphere from light from the sun. This causes the temperature to rise and increase at a steady pace. This can cause many species on this earth to become extinct as they cannot adapt to the changes made by global warming.

The greenhouse effect is when the temperature rises because the heat from the sun is trapped in the earth’s atmosphere. The heat and light can get through the earth’s atmosphere but it can’t get out making the temperature rise. The heat gets into the atmosphere but then is trapped and makes the earth’s atmosphere hotter. Sometimes the temperature can change in way that benefits us. The greenhouse effect makes the earth the correct temperature for use to be able to live.

Without it the earth would be freezing cold or burning hot. It would be cold because at night there would be no sun to provide heat and light and during the day it would be burning hot as there would be no atmosphere to filter the light and heat. However the atmosphere helps to keep the earth the right temperature by filtering the heat and light during the day to stop it from being very hot and during the night the atmosphere helps to keep the heat as there is no sun to provide heat and light. Without the greenhouse effect many animals, plants and people will not be able to survive.

Most scientists believe that main cause of global warming is the green house gasses that are produced. They also believe if there are too many greenhouse gases in the atmosphere then it will become too thick making the earth heat up even more. As a result of this many people, animals and plants will die. Some sources of greenhouse gasses are water vapour, carbon dioxide methane and nitrous oxide. These are natural gases, humans put extra greenhouse gases into the atmosphere by wasting extra energy. All of these green house gases are linked to global warming.

There are many causes of global warming; one of these is electrical pollution, electricity causes pollution in different ways some of which are worse than others. In most cases electricity is created by burning fossil fuels (non renewable source) which are made by dead plants and animals. This has a negative impact on our environment. These sources will soon run out. Examples of fossil fuels are petroleum and oil. Many chemicals that pollute the air, land and water are sent into the air when fossil fuels are burned. Some of the chemicals are called greenhouse gases. These sources of energy give off more pollution yet they are the sources which are used most. Petroleum is used a lot for transportation, creating electricity and running and making many other things.

This is used for 38% of the United States energy although it is very polluting. The cutting down of rainforests to use the wood for paper and other things is indirectly causing extra global warming because these trees help keep the Earth’s temperature low, and help make oxygen. The fewer trees the more carbon dioxide because trees take in a carbon dioxide and give out oxygen which helps animals live and reduces amount of carbon dioxide. Animal waste gives out methane which can harm to our environment and contributes towards global warming.

The changes which could happen to our environment if global warming continues.

If the earth continues to get hotter then it will cause the sea levels to rise and will change the pattern and amount of precipitation and will increase the amount of subtropical deserts. If sea levels rise it will flood islands and countries at sea level. The biggest affect will be on the Arctic Sea because the increase in temperature will continue to melt the glaciers and they will shrink as well as the sea ice and permafrost. It will change the regularity and strength of extreme weather, extinction of many species and changes in the agricultural yields. Changes will vary from region to region. If plants are destroyed animals and humans may die of hunger.

There will be many changes to our environment if global warming continues these include: Ice melting in Greenland and Antarctica, this will accelerate the rise of sea levels. The speed at which global warming is expected to occur is faster than what plants and animals can cope with and adapt to any changes. Some species may adapt but others may become extinct. Ice glaciers will melt because of the higher temperature and will add to the rising sea levels. This may put the coasts of many cities in danger of floods and could put whole countries and islands under water. Countries with that are used to cold weather may face the hot weather and water sources will dry out and many places will become deserts where it impossible to live.

Large lakes and rivers may dry up which could be the only available source of water and could kill many people. Because of the higher temperature it will cause more draughts decreasing the time farmers have to grow food and it will become windier. Hurricane may become more common in new places and could have damaging effects as those countries will not have ways to reduce damage set in place as they will have never faced a hurricane or storm in that country before. There will have to be limits made to the amount of mineral water that can be bought and the amount of water that can be used for showering etc. There could be water shortages. Many species of plants will die out and eventually become extinct if they cannot adapt to the changes.

Other things that could happen are that diseases will spread as northern countries become warmer; insects which carry disease will migrate north and brings plague and disease with them. However, some scientists believe that in some countries malaria has not fully eradicated and is being revived in countries where it was disappeared from. Although some areas of the world will become wetter, others will suffer from serious and heat waves. Water is already not enough in Africa and global warming will worsen the conditions and could lead to conflicts and war. Most of the effects of global warming won’t be good and the effects will lead to economic consequences for countries. The hurricanes will cause billions of dollars worth of damage and diseases will cost billions to treat and control and the conflicts will worsen all of these.

The main change will be that the polar ice caps are melting. By this there will be four major effects caused by this. First it will raise sea levels; there is 5,773,000 cubic miles of water in the ice caps, glaciers and permanent snow. Although the glaciers aren’t going to melt straight away the sea level is going to rise. If they were to melt the sea would rise by about 230 feet. Secondly the melting ice caps will disrupt the balance of the ecosystem. The ice caps are fresh water and when they mix with the salt water it will become less salty in other words it will desalinate the ocean.

This will change the ocean currents which regulate temperatures, this will cause the area around the north-east America and Western Europe to cool down, and the good affect is that it will slow down the effects of global warming in this area. The third affect is that the changing landscapes in the Arctic Circle will endanger many species of animals and plants and only the ones that can adapt well will survive. The last main affect that melting of the ice caps is that global warming could escalate if the ice caps are gone because they reflect sunlight as they are white. The process of global warming will speed up because the only thing to reflect the sunlight will be the ocean but that is a dark colour and would absorb the heat and further heat the earth instead of cool down.

Things that can be done to slow down climate change.

One thing that is being done at the moment is that the United Nations has meetings where world leaders agree on what they can do about global warming. Every 5 years there is an Earth Summit that takes place. It takes place every five years and in 1997 it took place in Rio de Janeiro. An agreement was made at the UN conference on climate change in Kyoto, Japan. The agreement was that everyone had to reduce the amount of gases produced by industries. The leaders agreed that the world can cut down the amount of carbon dioxide that is released into the earth’s atmosphere by changing the way power is produced.

They agreed that they will do this by changing the methods that are used to produce power to methods that release fewer amounts of carbon dioxide. The leaders from different countries agreed that they will try and produce energy in ways that release fewer amounts of green house gases into the atmosphere to reduce the amount of harm to the environment and to try and slow down the effects of global warming. Later in February 2003, the British Government broadcasted their plans to produce electricity using greener methods.

Ways to cut down greenhouse gases

There are many ways that can help cut down greenhouse gases, this can be done by everyone making a few changes to their day to day life. If everyone contributes substantial changes can be made as there are billions of people in the world.

The first thing that can be done is that everyone should recycle glass bottles and jars instead of throwing them in the rubbish. They can be cleaned and then reused, if people don’t recycle businesses will have to produce them from scratch which adds to greenhouse gases and costs more as well as using up the earths resources. Everyone can also recycle newspapers and magazines that they read so that the paper can be reused instead of being burnt at landfills and companies will have to cut down more trees to make more paper. If this paper is reused then it will reduce the amount of trees being cut down. Another thing that can be recycled is tin cans as they are made of steel and other metals they are sources from the earth that may run out if new metal is being used to make tins instead of recycling used tins.

All of these things should be collected and given to the recycling centres where they will be sorted and recycled. The glass bottles can be used again to produce glass bottles or glass can be melted to produce other things that are made of glass. The paper and card items can be reused and recycled to use again by company’s newspaper companies and can be used to make recycled paper books. All of these things can be reused or recycled o make something else out of the same material instead of having to produce the material from scratch which produces a lot of greenhouse gases.

Another thing that everyone can do is that when they go shopping they should reuse the bags from last time by bringing them back with them and using them again to take the shopping home instead of using new ones. Each person can save around 5 bags each on average and this will benefit a lot when it comes to reducing greenhouse gases from being released into the atmosphere. Plastic bags should be recycled because this can be easily done and the plastic bags aren’t degradable. Bags could be made out of fabric so it can be used again and again as it won’t rip and is hard wearing. Or paper can be used as it is recyclable and wont need to be burnt as it won’t go into landfill sites.

Another way that greenhouse can be reduced is buy buying products with less excess packaging and businesses should avoid fancy excess packaging and tell the buyers that this product is the same but it just has less packaging to help the environment.

People can also persuade people who do gardening to have a compost heap so that waste food can be turned into compost and reused, and compost that is going to be thrown away should be given to someone else who is going to use new compost for gardening etc.

A way to reduce the amount of water used for flushing people should put a brick into their toilets cistern so that less water is used each time you flush and this will dramatically reduce the amount of water used for flushing if many people follow this.

Clothes and gifts that are unwanted should be given to charity shops so that they can be used instead of being thrown in the bin and adding to the landfill sites, by doing this you will be helping the environment by reducing the amount of items that are thrown into landfills and it will help poor people who cannot afford to buy new things.

A way to save electricity is by only filling the kettle up with the amount of water you need at that time so extra electricity isn’t used to boil the unneeded water. Another way to save electricity is by switching the TV off from the socket so it isn’t on stand by when no one is watching TV. Other items should also be switched off from the socket when not being used such as gaming devices and computers so that they don’t waste electricity when they aren’t being used.

A way to save using the car or reduce the amount of cars going to the same place you can give your friends a lift if your going to school so they don’t have to go in their own car or you should just walk to school with your friends to reduce the amount of petrol being used and to reduce carbon emissions and it is also good for your health. Public transport should be used as much as possible as many people are only using one vehicle and it reduces the amount of cars on the road. If a car is necessary then buy a hybrid car as they produce no carbon emissions and only use electricity.

You should use washing machines at lower temperatures, lots of brands of washing powders make their powders which can be used at lower temperatures and do the same job f they were used at higher temperatures. Lower temperatures to 40 or 30 degrees, this will help conserve power and is good for the environment. To save gas for heating water and to reduce amount of water being used people should have showers instead of baths as they use less water and are quicker so less water is used. If a room is not being used then everything including lights should be switched off to save energy from items when they are not being used.

Advantages and Disadvantages of using different methods to make energy

In this section of my work I am going to describe the advantages and disadvantages of using different ways to produce energy. There are methods of producing energy that are less damaging than others, some of these sources are renewable which is good because they wont run out. The five methods I am going to talk about are wave power, wind power, waterpower, solar power and using bio fuels.

Wave Power

Advantages

The advantage of using wave power is that it is run by itself and doesn’t need to be run by people, there is not cost expect for when you build the power station to use the wave power to make electricity. The advantage is that it doesn’t give out greenhouse gases and doesn’t contribute to global warming. It is a safe way of creating electricity and doesn’t need to be watched closely.

Disadvantages

The disadvantages are that it may not always be windy to make waves and sometimes the waves may be too big, this method is highly dependant on the wind and will not always be reliable as it is a relatively new way of creating electricity. It costs a lot to build a station and it will cost a lot to maintain it, and it may be damaged because of large waves. They are far out into the sea and will require something to be built to transport the electricity back to the land which will be costly and hard to build at the sea bed. They are noisy and will disturb people living next to the shore who may complain against it.

Wind Power

Advantages

Wind power is also free like wave power, and will run for free without any continual costs and similarly to wave power the only cost is building the wind turbine and maintaining it. Wind turbines don’t need any fuel or energy to run them so there are no emissions produced. The wind turns the turbine and it works itself to create electricity. The wind power generators don’t release any greenhouse gases into the atmosphere so therefore help slow down global warming because other ways to produce electricity such as burning fossils fuels will release carbon dioxide and other harmful gases into the atmosphere so wind power is better and cheaper. The land near or under the wind turbines is not wasted and can be used for farming etc. It is on land and therefore the electricity can be stored or transported easily using cables etc.

Disadvantages

The disadvantages of wind power are that many wind turbines will be needed as they don’t create that much electricity and this could take a lot of space. It may not be windy all of the time and no electricity will be produced without wind. In countries where it is hot and not windy wind turbines will not work as they won’t turn to make the electricity, they can only be used in countries where it is windy most of the year. Most of the time the best place for wind turbines is on the coast where it is windy but these locations are more expensive. Many people believe that they ruin the scenery and take away the beauty of the land, it disrupts nice views. They are noisy and will disturb people living close to them. However as technology is improving, wind turbines will become more aerodynamic which will reduce noise levels.

Waterpower

Advantages

The advantages are that once the dam is constructed the electricity will be produced at a constant rate. If the electricity is not needed then the sluice gates can be closed to stop the electricity from being generated. The water can be saved for use at another time when electricity demand is high. Dams are designed to last for a long time and can be relied on to provide electricity for many years. The lake formed by the dam can be used for water sports and leisure and they can become a tourist attraction. The lake’s water can be used for irrigation purposes as well as producing electricity. The build up of water in the lake means that the energy can be stores and when the water is released to produce electricity. The electricity produced by the dam doesn’t release any greenhouse gases and doesn’t pollute the atmosphere.

Disadvantages

The disadvantages are that they are extremely hard to construct and are expensive and must be built to a high standard so they can run smoothly. To become profitable they must run for many decades to cover the cost of construction and to make a profit. This damages the surrounding environment because large areas must be flooded and the animals and plants will be killed in that area. The people living in the valleys to be flooded must move away which means that they will lose their farms and businesses.

In some countries those people are removed by force, they must be paid or given another home to live in. The building of large dams causes geological damage, for example the Hoover Dam in the USA caused earthquakes and compressed the earth’s surface in that area. Dams have been known to collapse under the pressure of the water and this causes deaths and damage to surrounding area. Dams in a river is blocking the progress of the river and if the river is running through two countries then it will be under the countries control which has the dam and will cause problems between the two countries.

Solar Power

Advantages

The advantage of solar power is that it is free and doesn’t require any fuel and it doesn’t produce any waste or pollution, it will benefit countries a lot that have a lot of sunlight and can be used everywhere. It is good for remote places where there is no electricity such as poor parts of Africa as it is very sunny all of the time and can be used all the time and will provide them with electricity. It reduces energy bills for people and it is a renewable source. We know it can be used everyday and can rely on it although it cannot be used 24 hours a day the electricity can be stored, they are totally silent and doesn’t produce any greenhouse gases or any pollution at all. The energy produced by it is free except the start up cost. They require no maintenance as there are no moving parts.

Disadvantages

The disadvantages are that it is very expensive to buy and install and many people won’t be able to afford it. And another disadvantage is that no electricity is produced at night and can be bad if a lot of energy needs to be produced. They cannot produce a lot of electricity and will be unreliable in countries such as the UK where it is cloudy and rainy most of the year. Large Panels will need to be installed to run a house and it will cost too much but will help the environment and could benefit the buyer in the long run after it has covered the start up cost.

Bio-fuels

Advantages

This fuel reduces the amount of greenhouse gases produced when compared to conventional transport fuels. The first generation bio fuels can save up to 60% on carbon emissions compared to fossil fuels. Even better the second generation bio fuels can save up to 80% of carbon emissions.

It can be made from many sources such as: plants material, fungi, etc. Due to these sources being available all the time, it can be reproduced on a huge scale, demanding on how much is in demand. It is unlimited as there are so many sources renewable that it can be made from. It will create for jobs for people to do, who are jobless, which is also helping the economy of different countries at the same time. It is safe to handle and is less dangerous than gasoline, so less health affects. It helps the drivers who use bio fuels to fuel their cars to save money s the government has introduced incentives for drivers who drive green cars with reduced tax. With petrol prices rising, replacing petrol with a renewable energy source will offer significant savings in the long run as they are more readily available. They are helping employment overseas as it offers jobs and has a positive effect on energy prices.

Disadvantages

In actual fact they are not carbon neutral because it needs energy to grow the crops and then convert them into fuel. Fuel is used to power machinery and to transport crops and this does have a impact on the overall benefits of bio fuels, However they still are more environmentally friendly than fossil fuels and other alternatives. There needs to be more money invested into making bio fuel cars. The problems are that it has to be built in remote locations where no one lives because bad smells are given off. This will affect the countryside as they may be built here and it will affect people who live near to it.

I think that the data in the tables is valid because it gives us approximate and accurate data which relates to that specific part. The first two tables are at a constant rate and are comparing temperature variation as the years go by and the decreasing thickness of ice. The first graph has steady 20 year gaps which makes the data more to the point and keeps it consistent this is the same as well in the third graph. I think that the data in the tables is valid because it is correct that the thickness of ice will decrease as surface air temperature increases because of the increasing concentration of carbon dioxide in the atmosphere.

On the third table it shows us that the thickness of ice has decreased this is valid because from table one I can see that the surface temperature has raised meaning that the thickness of ice will decrease because of the higher temperature. This is valid because the data is from different locations and they all show the same trend, the thickness of ice has decreased in all of the locations within the arctic sea at the same years and not at different years. It is valid as you can make a conclusion from the given data, as global concentration of carbon dioxide increases the surface air temperature rises and the thickness of ice decreases because of this. This is evidence that the earth is becoming warmer.

I think that the data in the tables is reliable because it tells you precise amounts and gives you figures from different time periods. The figures cannot be biased as they are data and not an opinion. The figures seam to be realistic and are likely to be true as the source is the BBC which is a known organisation which doesn’t take sides and is there just to inform. They are a reliable organisation and they are professional so they put valid and reliable information on their website. They are not biased as they just inform and provide proof that the planet is getting warmer and how this has happened. They provide the whole story and not just one part of it, for example they don’t just provide information about the bad effects and why it has happened.

They show how global warming has come about from increasing amounts of carbon dioxide in the atmosphere an then increasing surface air temperature which decreases the thickness of ice. They provide people with the correct information so they can do something about it and don’t support letting global warming carry on, they want something done so they have given exact information and provided proof of why it is happening and how much has already happened. This is shown by given ice thickness in two time periods to show that it is actually happening and how much ice has already melted.

Personally I believe that in the UK we should have more wind farms to help reduce the carbon emissions produced to make electricity through burning fossil fuels etc. In my opinion I think that wind power is the easiest and most reliable to help the UK in reducing the amount of greenhouse gasses they release into the air. I believe this because here in the UK it is always very windy so we might as well use the wind to help us. It is a free source and is good for the environment as it helps produce electricity using a renewable source. The land used by the wind turbines will not be wasted as farmers can use the surrounding area for growing crops etc, they have no damaging affect to our environment, and they just ruin the view of the countryside.

This source of energy is better than solar power in the UK as it isn’t sunny that much and hardly any electricity will be produced whereas it is always windy and wind turbines will work most of the time throughout the year. Solar power would be least reliable in the UK but in other locations such as Africa it is always sunny and people don’t always have access to electricity so they can use solar panels to make their own electricity. Wave power is complicated as a station has to be built in the sea which is expensive and really hard to build. This is much too complicated and instead we can use wind power which is very reliable and is easy to start and isn’t too expensive and doesn’t require maintenance. I know that wind turbines take a lot of space but they can be made on unused land near the motorways and it is already very noisy there so it won’t really affect anyone as hardly any people live near motorways.

They can be built in the country side where no one lives so no one will be affected by it being there. It is the easiest and quickest way of producing electricity if they are built on hills as it is always windy there. They will be efficient and will provide power without damaging the environment and won’t release any pollution into the air or atmosphere what so ever. They have no damaging effects on the environment and they are being developed to be quieter as technology is moving on by making them aerodynamic. By doing this they can be made in city areas as they won’t produce too much noise pollution. They don’t damage the views that much and many tourists think they are a work of art built into the countryside. If people do think it ruins the view it is better than global warming.
