...only life that will suffer? The planet will recover when we're gone.

Why do we say we have to save the planet from global warming when it's really...

Why do you think life will suffer? Lots of species have benefited from the warming.
Just 18,000 years ago, the Earth was gripped in a deadly ice age. Life suffered as ice a thousand feet high pulverized the land, crushed the forests and ground up the rocks into gravel and dust. The permanent glaciers came as far south as New York, Kentucky, London and Turkey.
Then the warming cycle hit. The ice was driven back rapidly, exposing billions of acres of new land for forests, wildlife, human farms and habitat... What we live in now is the result of drastic global warming. How bad is it?
All of that warming, driving the glaciers back by over 2,000 miles, happened with no human help whatsoever. If humans were to vanish tomorrow, it would continue as it has been for thousands of years. Think about that - even if we did not exist at all, the Earth would have warmed drastically - and it already has.
As the Earth warms, it becomes more Green. Carbon Dioxide, the primary fertilizer in our ecosystem, is released. It feeds the plants, which provide food for animals, and which create the oxygen we breathe from CO2 and sunlight. The more CO2 there is, the more water-efficient plants become. Today's plants are starved for CO2, which was depleted from the atmosphere during the last Ice Age.
Life loves a greenhouse, not a glacier.

Because this day and age, politicians, and pretty much nearly everybody only cares about there own life, and they feel that human beings are the greatest thing in the universe and they want to do anything to try and make us last here for as long as possible.
But...from what i have read, they say that when global warming becomes too high, then life will finish, and that includes all forests, seas etc thus making the earth just a baron wasteland that can't support life. And this could last for millions of years, but who knows what would happen after the global warming has subsided, if it actually does.

Indeed it will. If you want an interesting thought experiment into that, read "The World Without Us," by Alan Weisman. Fun read.
Also, the people who say they're worried about global warming are really worried about:
1) the impact of rising temperatures on crop yields
2) the inability to feed booming populations with dwindling yields
3) the rapid depletion of non-replenishable fossil aquifers to irrigate crops
4) soil erosion and desertification
5) the likelihood that (as a result of the above) China will have to turn to the world grain market for food, which will cause a worldwide spike in food prices
6) the fact that entire nations will starve when they can't afford pricier grain, which leads to destabilized governments
Whether Global Warming is real or not, the above are observable, and given our sheer numbers, they are ticking bombs.
