It's the only planet we've got - and a small one to boot - which still manages to provide everything we need to survive.
What does the earth provide that makes it so well-quipped for human habitation? It includes an oxygen-rich atmosphere, a weather system that provides rain to grow crops, as well as fathoms of ocean to fish.
It makes it very easy to take it all for granted. Yet there's a price to pay for all this abundance, and that is the sure knowledge that all these rich resources are finite.
Right now, the air and water need for our existence are under threat everyday by pollution. Garbage that we throw away fills dumps with toxic residues that poison the environment.

Unless we start to take better care of the earth, it will not be able to continue to sustain us. But is it already too late?
It's been only a half century or so since the movement was spawned to raise awareness about exhausting the planet's riches, but after decades the push for environmental awareness remains an uphill battle.
