Water can be a blessing or a curse. Too often we make conservation about saving a whale, a coral reef or a marsh. But we don't make it about saving life. The one thing that every single human being has in common is our need for water.

For those who don't live in a place where water is readily available, it's something you carry on your back for six kilometers, that makes your children sick, that is perhaps the hardest part of your existence.

I believe water will be the defining crisis of our century — from droughts, storms, and floods to degrading water quality. We'll see major conflicts over water and the proliferation of water refugees. We inhabit a water planet, and unless we protect, manage, and restore that resource, the future will be a very different place from the one we imagine today.
