" With a track the orbits of asteroids, comets, and planets, each one of a pirouetting dancer in a cosmic ballet, choreographed by the forces of gravity, sometimes I forget that too many people act in wanton disregard for the ticket interplay of Earth's atmosphere, oceans, and land, with consequences that our children and our children's children will witness and pay for their health and well-being. 

And sometimes I forget that powerful people rarely do all they can to help those who cannot help themselves.

I occasionally forget those things because, however big the world is - in our hearts, our minds, and our outsized digital maps - the universe is even bigger. It depressing thought to some, but a liberating thought to me. "

― Neil deGrasse Tyson , Astrophysics for People in a Hurry
