This is the single most important problem we face. We seem to have the power to wreak the environment. Possibly to the extent of rendering the world uninhabitable by humans, certainly to the extent of killing off 90% of the human race (through global warming causing rising ocean levels that flood 90% of the world's arable land). Right now, and for the next 100 years, we have nowhere else to go. If we manage to destroy important parts of the Earth's ecosystem, we put at risk human civilization and possibly even human life. It is hard to be too concerned with this prospect. We don't have any fall back options. We can't live on any other planet or moon in our solar system.

The Earth is not as fragile as mainstream hysteria would have you believe.
Think of the earth as a very complicated pendulum. A real pendulum is one dimensional, it moves left or right. In this analogy, the Earth is a multi-dimensional pendulum. There are many variables (e.g. temperature, distance from sun, solar energy, carbon content in atmosphere) that describe the state of Earth's climate. The Earth's climate oscillates in these multiple dimensions (like a pendulum oscillates). This system is very complex and not understood, but we can conduct a simple mind experiment to prove its resilience.
What would it take to destroy a pendulum or push it to a state where it will not return to stable oscillation? Except for destroying the pendulum with a powerful force (like a bullet) or throwing the pendulum bob hard enough to break the string or hinge, the pendulum will always return to a stable state.
Like the pendulum, we'd have to assert a powerful force on the earth to irrevocably knock it out of a stable oscillation.
We will also have to assume that the Earth has never experienced such a force because it currently exists in a stable oscillation. Here's where this mind experiment becomes a matter of judgment. Is man's influence on the Earth more powerful than any previous event in earth's history. For example:
1. Earth's moon is theorized to be the result of a collision between the earth and another large mars size object.
2. Earth has experienced countless comet and asteroid collisions, some large enough to blacken the sky and cause mass extinction.
3. Earth regularly experiences catastrophic volcanic activity such as Mount Vesuvius
Earth has withstood 4.57 billion years of these catastrophic events and still remains in its stable state. Since these events did not destabilize Earth, why should we expect human activity to destabilize Earth? We would have to exert a force greater than anything in Earth's history to even explore the possibility of destabilizing earth. Do you believe we are that powerful? I don't, not yet anyway.

she will have a sex change and become father earth, she'll get a house somewhere in silicon valley and become a waitress while trying to break into the world of acting.
seriously though,
not too much. is there a problem with pollution? yes. however, its not nearly as bad as some of these EPA radicals would make you think. there are enough people in the world who do their part, or even more than their part to make sure the world doesnt die on us in the next fifty years, five hundred years, may be another story. as far as global warming, is the world getting warmer? yes, will it continue to the point where we all boil to death? no. the climate changes, thats what it does, thats what its been doing for the last 6 million years or however long the earth has been around. relax, dont be afriad of change.

Rich countries will be poorer. Poor countries will have seen a lot of death.
Flooding "90% of arable land" is a wild exaggeration. But flooding 10% will do in some poor countries. The US can cope, but it will cost a lot of money and lower our standard of living.
Exaggerating the catastrophic nature of global warming makes some people disbelieve the whole thing. The truth is bad enough, if not so spectacular to people who watch disaster movies. It won't be like that.

Mother earth will be just fine.
The population of humans on the planet will have to drop by about three billion. Since most people will not be willing to just stand by and starve to death we will have world war three.
Humans won't like it much but the planet will shake it off and be just fine.

Mother earth will still be here but it won't b the same as today. Later approximately in 1000 years, this great mother earth will no more exist and what will happen next, no one know!

Mother earh will probably die like the rest of us, unfulfilled, bitter and with a deep sense of regret. The planet Earth however appears to be doomed………

Mother Earth will still be here. I don't know what will happen to the inhabitants, though.

We could have the tech..to protect our earth.or we could die because of climate change but i my self think that earth will be destroyed.Stephen Hawking was right our main concern right now is not terrorism but the climate change.
