Bio meaning life and diversity mean variety; biodiversity is the variety of life at every trophic level from microorganisms to the largest species of plants and animals. Biodiversity is a critical factor in a healthy environment, a part of the biosphere system. When parts of the system are not functioning well, the system starts to struggle, working inefficiently, or having the potential to break down completely.

An assessment of the best-known groups of U.S. plants and animals indicates that as many as one-third of America’s species are vulnerable, one in five is in danger and at high risk of extinction. It is critically important we provide children numerous opportunities to appreciate the natural world and teach them the skills required to be stewards of the land and its inhabitants.
