The definition of extinction is the end of an organism or group of organisms. The implications are staggering and one of great finality.

The ultimate moment of extinction means that that creature will never again be seen on the Earth. Scientists believe we've gone through a number of these events throughout our history, and five are recognized as being major, planet-changing cataclysms.

Many believe that we are currently experiencing a sixth mass extinction, one of which the responsibility lies solely in the hands of man.

In this " 2 The Outdoors " special presentation, we'll take a look at what's happening across the globe and in our own back yard, and we'll suggest ways we can all take part in healing the wounds we've inflicted.
