Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms. Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today's oceans at an alarming pace -- so fast that scientists aren't entirely sure how the planet will respond.

To put it bluntly - the Earth doesn't care about us. What ever we do, whatever environmental damage we cause, the Earth will recover and grow new life eventually. The only harm done by not paying attention to what effects we have on our climate is to ourselves. If we don't get a swift handle on the overpopulation, accelerated climate change, pollution, & biological destruction we are causing, WE will be the ones going extinct.
People tend to forget that as long as we are on this rock we are subject to this rocks rules. While we may feel we are the superior beings on this rock mother nature will soon prove us wrong. Global warming is not always man made but man has made it worse.
All true. Modern society has a gimme attitude that doesn't care about the costs involved so we are seeing the results of that now but there is even worst to come.

Leading Antarctic experts offer two possible views of continent's future. The next 10 years will be critical for the future of Antarctica, and choices made will have long-lasting consequences, says an international group of Antarctic research scientists. It lays out two different plausible future scenarios for the continent and its Southern Ocean over the next 50 years. Source 3k.
In my opinion there is no hard argument that the current global warming isn't man made. It's not necessarily a bad thing, it more shows how far we have come to be able to effect a planet at this scale. Right now its more of making the right decisions on what to do next and how to handle what could very well become a future crisis.
In a warming climate, Arctic geese are rushing north. As Arctic temperatures continue to rise, migratory barnacle geese have responded by speeding up their 3,000-kilometer migration in order to reach their destination more quickly with fewer stops along the way, according to new evidence. Unfortunately, the birds' earlier arrival isn't making as much of a difference as one might expect. Source 9o.
