In another thread a poster brought up the idea that things like global warming and depletion of the earth's resources are just "urban legends". Even the Bush folks admit the world is getting warmer and the ice caps are melting, they just don't want to say human industry is the cause in order to protect economic interests. So are we endlessly sustainable? In the last 20 years we have lost 114 species of animal and plant life (these are things that have not been seen in 20 years- they are either gone or very good at hiding from scientists http://www.msnbc.msn.com/id/4806272/). Our oceans are in serious trouble (just ask any deep sea fisherman http://www.sciencenews.org/articles/20030726/bob10.asp) - does this seem a problem to anyone? I know many people look to the philosophy of homesteading as a way to live a less materialistic/consumer lifestyle. A benefit of this lifestyle is being able to live closer to the real world of plants and animals and less in the world of plastic and steel. Does the natural world seem to be endlessly sustainable to you? Is collapse possible? Did God create this world for us to demolish like a spoiled children with toys? Many people on this forum worry about economic depression- does anyone worry about environmental shifts that will make it impossible to grow crops. Pollution from Europe is believed to have caused droughts in Africa (can't find my link you will have to Google it yourself)? Could it happen in your part of the world? As humans need more space and resources what are you willing to lose - lady slipper orchids, a few beetles, song birds, whales, polar bears, other people?- where do you draw the line? Sorry to be such a gloom bringer, but it's been on mind and I just wonder what other folks are thinking - if anything.
