The human being will become extinct one day

There's something wrong with the world today,
I dont know what it is,
Somethings wrong with our eyes,
We're seeing things in a different way,
God knows it ain't His,
Its surely no surprise,
Yeah, we're livin on the edge.

Steve Tyler wrote these words sometime when he saw the world crumbling to bits. It sure is crumbling to bits, isn't it? We humans are eating it all up. And we want more. More of the world to plunder and pillage. We don't want to stop. I had a passionate discussion with a friend of mine sometime back about this. She wanted data on Global Warming and climate change. Words tossed around too oft these days. What I don't understand is why do people actually lie to themselves in seeming interested in saving the Earth, per se, to look fashionable, perhaps?
The same people who "want" to do something are the same people who do not take a bus instead of an auto-rickshaw, the same people who go to the market and bring home polythene bags instead of carrying their own cloth bags with them, the same people who do not turn off their monitors before going home, the same people who waste half a dozen tissue papers each time they wash their hands. Those are the same people who buy a car with their hiked salaries and commute alone, leaving behind a gargantuan carbon footprint. And these people claim to be interested in saving Mother Earth?
We humans are the only species that I'm aware of that's capable of slaughtering it's own brethren. And finding better ways to do away with more and more of them. We clear out rainforests everyday, and yet we cringe when someone brings up the topic of Climate Change in a conversation. I have actually been in situations where people have turned around and walked off claiming to have "work" to do when this topic came up. So this friend of mine, she asks me, why don't people do anything about things they only talk about? I had just one answer for it. It's not like we can't change. It's more like we don't WANT to change. We dont want to make changes to the choices we make everyday. We don't want to change ourselves. We would rather make fun of someone making an honest effort rather than look within ourselves and think about whether what we're doing is right or not.
And at the end of it all, when we all would have died, and death and disease has claimed every one of us the very last human being will think, "Did we do this to ourselves?" but he would already know the answer.
It's true that the human being will become extinct one day. God knows, we deserve it.
