    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 ...
