The program introduces the basic concepts of biodiversity, and takes a close-up look at salmon, rainforests, and marine ecosystems as examples.

Amongst those interviewed are Harvard's Edward O. Wilson, known as the "father of biodiversity"; Dr. Robert Paine, who coined the phrase "keystone species"; and forester Dr. Jerry Franklin.

Many programs call for us all to consume less in order to leave enough room for other species, on whom ultimately our survival depends. Few do it so effectively and positively.

Note: To make this program more user-friendly in the classroom, we have created a 5-part series:

The five programs in the series are:

Introduction to Biodiversity - The concept of biological diversity and its importance to humans.

The Significance of Salmon - Salmon and people both need clean water to survive. Can we make the connection?

Keystone Species - The principle of keystone species proves the interconnectedness of the living world.

Forests, Biodiversity and You - Can forests retain their productivity and biodiversity? Consuming less ourselves is key.

Biodiversity vs. Extinction - Mass extinction of species can be stopped if we understand the importance of biodiversity.

Reviews
"Astonishingly beautiful documentary...With gorgeous photography, straightforward writing and enthusiastic participation by scientists who don't come off as pedants...a wake-up call that is riveting and startling, but, more important, congenial, considerate and convincing."
