President Donald Trump has announced that the United States will no longer participate in the 2015 Paris climate agreement, the landmark United Nations treaty that many of us worked so hard to achieve.

Trump claims that he will try to renegotiate the deal reached in Paris, or craft a new one.

It affects every element of life on this planet — from ecosystems and food production to cities and industrial supply chains. Viewing climate change as strictly an "environmental" problem misses the point entirely.
