I created the "Planet Earth" topic because I just finished reading an article from Wired Planet called "Terraforming Earth: How to Wreck a Planet in 3,000 Years (Part 1)"
Hancock Wildlife Foundation is built upon the work of David Hancock, whom I've known for over 25 years now. We've spent long hours talking about our views on what man is doing to this planet and we come at the topic from two very different backgrounds and initially with two very different points of view.
Without putting words in David's mouth, I think I can characterize him as part of the solution instead of part of the problem - at least as much as possible within the limits of also being able to affect real change in as many people as he can. He might have been like some and gone "off grid" to live in isolation but "environmentally friendly" - but no, he's done other things and helped in other ways.
David early on was close to the birds he's most known for his teaching and researching about. He's watched the demise of species in many areas and participated in the re-introduction of them from stocks he's caught and raised personally. He believes in zero population growth as being fundamental to fixing the most basic problems of our planet - that of man's continued expansion at the peril of the other inhabitants of the planet; the fish, birds, mammals, insects etc. Nothing but the complete halt in population growth will make enough difference in the long term to save our planet from devastating consequences of the things we are doing to it.
I, on the other hand, come from a background of the typical middle-class North American family of the mid to late 20th century: 2.5 children per family (I'm one of 3 brothers and I have 2 sons myself now) and always striving to have bigger and better things to play with. I have a technical bent and read a lot of science fiction. Maybe I've been biased to ignore the planet's plight by my perception that science can either solve the immediate problem or provide a long-term solution in the form of new planets we can expand to as we out-grow this one.
The problem is, no scientific solution is going to happen soon enough.
