    Rain forests are complex ecosystems that are essentially self-sufficient when healthy. However, they are not easily regenerated once removed from an area. A healthy rain forest will, for instance, thrive by recycling most of the nutrients needed for plant growth between living plants, animals and decaying organic matter without outside intervention; however, it needs a large variety of organisms to do this. Once a parcel is deforested, it is unlikely that it will regrow to resemble its past condition without massive human intervention (which rarely occurs). In its place will likely grow a low-species- diversity assemblage of organisms that will eventually deplete the landscape of nutrients and therefore not be truly sustainable. Thus, rainforest loss is typically permanent.http://www.soest.hawaii.edu/GG/ASK/rainforest.html
