Not exactly...the thread is about the broader environment and Mankind's place and role in that environment. Farming in deforested areas is being used as a salient in that discussion.
However, Amazonian rainforests are now being cut down at an alarming rate--alarming to people who care about the environment and the amount of clean air a rainforest provides the world.
Implicit in your statement is that people who are not "alarmed" by such cutting do not care about the environment or the putative amount of clean air a rainforest provides to the world. That is little more than an attempt to falsely claim the moral highground for your side of the discussion and to cast the opposition as somehow immoral or degenerate. In point of fact, some of us are not overwrought about the forest clearing because we know that the environment changes, forests come and go and come again....People need to eat as well, Liz, and farming in former forested areas is one way to provide that food. As it happens, I think we ought to take a go slow approach to such clearing because I think there exists a strong likelihood that valuable plant and animal resources are being lost before they can be properly exploited. As for the clean air argument...its a false one, Liz. Grasslands are far more effective than rain forest at serving as the "lungs of the planet." In point of fact, the oceans are infinitely more effective that rain forest or grasslands. The entire "lungs of the planet" issue is a fabricated one intended to instil fear for the purpose of modifying behavior. I thought you were opposed to such fear mongering?
