Why don't people care about what they are doing to the Earth! I mean come on they are living in it!!!?

The reason is because they don't like to admit to doing wrong and even if something is right in front of us until it has been proven in all ways possible some people will not listen. People cannot directly see all the effects of things they do right away and thus feel they have done no wrong.

Because no one cares about anything anymore, unless it involves some ditzy blonde starlet. When was the last time you saw a war protest? Yet they line up in droves to protest Paris Hilton going to jail.

What cracks me up (in a sad sort of way) is people (usually Republican politicians) who talk about "those tree-hugging environmentalists" or other derogatory terms. And I always wonder the same thing....how can you NOT be an environmentalist? Don't you live on the same planet as I do? Or is it that, if there is money to be made in the short term, nothing else matters! It is amazing but happens all the time. There are a lot of people, that as long as they "get theirs" anything else that happens to the planet is someone else's problem. There is a wonderful little essay written about this called the "Tragedy of the Commons" by Garret Hardin, a thoughtful ecologist (now deceased) from U.C. Santa Barbara (see link).

not an answer, but a tiny comment to the question, and those who answered...When referring to people, and if you are one yourself a person, please use WE, and not THEY. -That is if you're not trying to disown yourself from the human race. thank u.

I know. a few years back the air wasn't as bad as it is today. You can just see the yellow smog in this town now. Don't they all know their adding to it. and the litter on the streets, don't they realize it has to end up somewhere. and the wasteful food. Gees. the third world countries are probably much better than us in terms of reuse and recycle.

As soon as they will realise that, it will be too late.

The issue has become far too political, so people feel obligated to draw a line in the sand and stand firm, rather than witness what is actually happening. Also, far too much emphasis is on saving the planet rather than improving our local environment like smog and polluted rivers. If people focused on the damage we're doing to our own living space, the health of our own air, etc. people would take it much more seriously.

Good answers all of them ,except of course Johnny B !!

I agree
