August 20, 2013 marks Earth Overshoot Day—the estimated date when we've used up the Earth's annual supply of renewable natural resources and carbon absorbing capacity. After that, we're using more than the planet can sustain. It's a one-day reminder of a year-round problem—we are living too large on a finite planet.
You probably have a general sense of why. Our human population continues to grow. We are consuming more and more resources. And we still have only one planet. To appreciate just how large we are living in relation to our finite planet, let's look more closely at some numbers.
Conservation is in the midst of a fundamental shift that I call "The Pivot." Conservation is pivoting from being backward-looking to forward-looking. This reorientation promises to expand what conservation can achieve by setting the stage for Conservation 3.0.
Despite frequent reference to the interests of future generations, conservation has mostly been a backward-looking endeavor. Hearkening back to "good old days" before extensive human impact on nature, conservation resisted change. It used verbs like "protect," "preserve," and "restore." It benchmarked success in terms of similarity to historical baselines. In short, conservation sought to make the future look as much as possible like the past.
The Arctic is an extraordinary and iconic place where wildlife is still abundant and ecosystems are still intact. Caribou herds migrate across vast tundra. Millions of seabirds nest on remote rocky islands. Walrus, narwhal and other marine mammals swim the seas. And polar bears hunt seals on the ice.
