Hands-On Natural Science Education

In 1972, when awareness of threats to the San Francisco Bay ecosystem began to grow, a group of women concerned about preserving the estuary for future generations created a small, hands-on program for local children, including a field trip to the Bay so they could experience it, know it, enjoy it, and grow to take care of it. This was the birth of the Environmental Volunteers. Since then, more than 300,000 children and adults have explored local ecosystems with the Environmental Volunteers.

Environmental Volunteers believes all children deserve to learn about the natural world through personal exploration, so they can become responsible stewards of the Earth. At the Environmental Volunteers we believe that what children appreciate and love, they will protect.
