Humans consume increasing amounts of the biosphere http://apocadocs.com/s.pl?1292518577
NASA satellite images have revealed that the biosphere is being placed under increasing strain as rising population on a global scale is accompanied by increased consumption of crops and animals per capita. If population and consumption continue to grow at present rates then by 2050 more than half of the new plant material generated on Earth each year will be required for humans. These findings were presented on Tuesday by NASA scientists at the American Geophysical Union (AGU) Fall Meeting in San Francisco.... "These images tell us very dramatically that we do need to look at what kind of impact human consumption rates have on the ability of the biosphere to generate the supply," said Imhoff. He believes that the need for more plant products will have big implications for land management. As more land is required for agriculture, planning authorities will be faced with difficult decisions as they try to protect important ecosystems, such as boreal forest.

Don't worry -- the natural law of "supply and demand" means that the biosphere will just produce more widgets.
