my main point is that we can't take ourselves outta what we do to the world, we are inevitably going to change it, and therefore we have to adapt (prolly should have used that word instead) to our consequences. it doesnt at all make it right tho.
i think its quite healthy that people are challenging the idea of global warming tho, being mainly attributed to what homo sapiens get up to...
as a zoologist i whole heartedly appreciate the need to try and preserve what we have. but i think its also important to recognise that we are only in the here and now, the planet has gone through many periods of warming and cooling, and this has led to evolutionary changes and differing levels of species diversity.
there have been many more (and greater) mass extinctions that what humans have done, and allthough i dont think we should use that as an excuse, the point is that the building blocks of life still exist beyond what we can possibly do to the planet, and life will go on...
the thing with this earth hour, as raised before, is that anyone can see that its not going to do anything. if one hour of non electrical usage can change the millions of hours of usage, then i think we would have been in a LOT of trouble, a LONG time ago.
the real solution and bottom line is this: GO NUCLEAR. 
radioactivity is what makes the world go round (literally). |
wow. a well-reasoned, well-argued, mature and considerate post by gumble. i think i just fell off my chair we mostly agree then.

who says global warming is a bad thing anyway? would you all prefer to live in an ice age? |
moderate, natural changes in weather isnt a bad thing. but a continual rise in temperature, brought on my artificial means (ie us) is a bad thing. it occurs infinitely faster than natural warming and as such the natural organisms dont have the time to adjust. so they die. there arent too many people that argue the warming in the last 80 or so years is natural.
ultimately, we can't afford to take the view that global warming isn't a bad thing, coz by the time we're really dealing with the fallout, it'll be too late (on many fronts) to do anything about it.
