July 6,2010 List the four principles of sustainability and discuss. Reliance on Solar Energy: the sun warms the planet and supports photosynthesis used by plants to provide for us and other animals. Biodiversity: a great variety of genes, species, ecosystems, and ecological processes have provided many ways to adapt to changing environmental conditions throughout the 3. 7-billion-year history of life on the earth. Population Control: competition for limited resources among n species places a limit on how much any one population can grow beyond those limits, its size decreases from changes in the birth rates and death rates of its members.
In nature, no population can grow indefinitely. Nutrient Recycling: natural processes recycle all chemicals or nutrients that plants and animals need to stay alive and reproduce. In this recycling process, the wastes or dead bodies of all organisms. There is little waste in nature. What is an environmentally sustainable society? An environmentally sustainable society satisfies the basic needs of its people without depleting or degrading its natural resources and thereby preventing current and future generations of humans and other species from meeting their basic needs.
For humans to live sustainably, the Earth’s resources must be used at a rate at which they can be replenished. There are many ways we can create a sustainable society by running on solar energy, recycling nutrients and wastes and this would prevent and reduce waste and pollution. Controlling population size and resources on the use of species by recognizing natures limits on population size and resource use and learn to live within these limits.
