“The whole world is singing – from the Arctic to the deep jungles,” states a wistful beginning to the Discovery Channel's documentary film “Racing Extinction.” Scientists share whale song and bird calls that are disappearing forever. The program teaches what most conservationists already know: that we have entered a sixth period of mass extinction in Earth’s 4.6 billion-year history. The Anthropocene – the time of humans – marks as great an extinction occurrence as the mass extinction that killed off the dinosaurs 65 million years ago by an asteroid strike. This time, the documentary says, “humans are the asteroid.” Scientists predict we could lose half the species on the planet in 100 years.
If you’re paying attention at all, you know this already. But you may not know how close we are to a point of no return. The vast ocean’s chemistry is changing. When carbon dioxide is absorbed by the ocean, it becomes carbonic acid. On contact, shells dissolve. The ocean is becoming uninhabitable.
The microscopic images of plankton are beautiful, neon-lit wonders. I had never seen these images nor did I know that we get half of the oxygen on the planet, the very air we breathe, from plankton. Forty percent of the plankton will disappear in 50 years due to climate change.
Habitat loss, over-fishing, and an inefficient human diet that requires 1.6 billion methane-belching cows to supply our meat-based diet all add to our planetary problem. But more alarming than all this is the exponential rate at which our planet will heat up if we melt the protective layer over the tundra that stores methane. Once the ice melts and methane is unleashed, there’s no putting it back. Change will happen exponentially and wondrous life will die, never to return. Then people will be the endangered species. Our air, our food, our water are all at risk.
Profits, a short attention span, or towing the party line results in most people being unconcerned, even when the tenants of their proclaimed faith include being a good steward of the Earth.
The documentary shares individual conservation success stories. So if you watched until the heart-breaking end, I hope that is the takeaway. Jane Goodall quots the Chinese proverb that it is better to light one candle than to curse the darkness. Watch it and weep. But then decide to act.
Be the light. Elect people who are trying to solve environmental problems. Fight for good climate change policy and clean energy. Give up meat for some of your meals. Invest in solar. Reduce your impact. Support land conservation.
E. O. Wilson, famous Pulitzer Prize-winning Harvard entomologist says that the solution to saving life on the planet is to create large reserves. If the world will act to stop climate change, then in Tennessee, let’s be ready to provide woods, waters, and wildlife habitat so that Tennessee and the Earth will still sing.

Conservation, viewed in its entirety, is the slow and laborious unfolding of a new relationship between people and land.
There is in fact no distinction between the fate of the land and the fate of the people. When one is abused, the other suffers.
From the President
SCP President Chuck Roe looked at land conservation along the route of John Muir's "Southern Trek."
