Health has always been an important thing to me. I exercise and try to take care of myself and drink a lot of water! And I push that to my kids so that they can carry on that same energy.

The biggest tab the public picks up for fossil fuels has to do with what economists call 'external costs ' like the health effects of air and water pollution.

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.
