You have been asked to prepare a presentation for the annual convention of Citizens for a Greener Planet, a national environmental group, on the idea of sustainable development.
Explain the following:
1. Define sustainability.
2. Describe the cycling and recycling of carbon, phosphorus, and nitrogen through both the living (biotic) and nonliving (abiotic) components of ecosystems.
3. Explain sustainability and stewardship when pertaining to the factors that brought about the collapse of the Easter Island civilization.
Sustainability can be thought of living in such as way that we do not degrade environmental resources. Thus, future generations are left with the same conditions as we have now. The use of resources is sustainable if nature can replenish all of the resources we use.
Carbon is cycled though the atmosphere as carbon dioxide. It is produced by respiration and by the destruction of tissue and vegetation. Once in the atmosphere, it can be taken in by plants and the cycle is continued. Carbon dioxide can also be absorbed by the oceans and ultimately by limestone, beginning the cycle anew. Another source of carbon is volcanoes. This part of the cycle is ...
This solution discusses the recycling of elements in the ecosystem, with a definition of sustainability and the collapse of Easter Island's civilization in 400 words with one reference.
Revolutionary changes in human culture; sustainability, stewardship, and sound science.
1. Revolutionary changes in human culture have greatly changed the relationship between humans and the environment. How have the Neolithic and Industrial Revolution impacted the natural environment, and what is meant by the Environmental Revolution?
The recycling of elements is another vital functional process occurring in all ecosystems. Describe the biogeochemical cycles for carbon, phosphorous, and nitrogen. How have humans impacted these three cycles?
The goods and services performed by natural ecosystems are essential to human survival. What is their overall value, and of what significance is it to measure this value.
2. Discuss fundamental concepts of Environmental Science: sustainability, stewardship, and sound science.
? Describe abiotic and biotic factors and their relationship to an ecosystem.
? Apply critical thinking skills to the content of the course.
