It's an important point, and every little bit helps not least because those who make those kinds of changes are more likely to make their voices heard as citizens. But the ultimate solutions are going to come through policies.

The climate crisis is the greatest challenge humanity has ever faced. From not only the warming of the earth with higher global temperatures, but also from strengthening storms and expanding droughts to melting ice and rising seas, the costs of carbon pollution are already being felt by governments, corporations, taxpayers and families around the world. The climate crisis will affect everything that we love and alter the course of our future. Now, more than ever, we must come together to solve this global crisis. We must act decisively, rise to the occasion and solve this monumental challenge.

The global environment crisis is, as we say in Tennessee, real as rain, and I cannot stand the thought of leaving my children with a degraded earth and a diminished future.

Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago.
