The current zeitgeist is extremely anti-human and anti-technology. You see this in comments like "we don't need more children, having children is selfish", when much of the developed world is already way below replacement rate, sometimes as low as 1-1.3. What they're saying is of course that _other_ people shouldn't exist but they should be allowed to remain and enjoy the now pristine nature. Global warming (which is very real) is used merely as a tool to further these ideas. They're the new Malthusians.
