As a captain for American Airlines, I have a great opportunity to see the effects of mankind on our planet. Unfortunately, some of these are not good. At 40,000 feet I see the pollution that permeates the horizon and I can only assume that this has a negative effect on all of us.

We all want clean air, clean water, and clean food. As the richest nation on Earth there is no reason why we should have anything less.

It is of great concern to me that in 2016 we still have some individuals and companies that are intentionally polluting our environment. We all understand an unintentional act but when it is intentional and blatant, enforcement and penalty must be swift and harsh.

As the global leader, our country has a unique position in the world. At times, leaders make decisions that may not be popular but serve the best interests of its people and the planet.

It is our duty to ensure our planet is safe, secure and sustainable for generations to come; otherwise we will have failed humanity.
