If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

I can't imagine anything more important than air, water, soil, energy and biodiversity. These are the things that keep us alive.

Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater, as well as accidental spills, can contaminate drinking water and harm human health.

It's not unexpected that shooting massive amounts of water, sand, and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren't the worst problem with fracking.

Think about a seed. Once it lands, it's stuck. It can't move to find better soil, moisture or sunlight. It's able to create every part of itself to grow and reproduce with the help of air, water and sun.

I think we can save reefs in the Caribbean and the Pacific. But we need proper water treatment systems throughout the world and large enough networks of marine reserves.
