Biodiversity is the variety of all life on Earth. It provides us with everything that makes life on Earth possible—clean air and water, fertile soil, medicines, fuels, materials, shelter, places for recreation, and a stable climate. This important part of our ecosystems is currently being threatened though, with reports showing that we have lost 60% of the global biodiversity in the last 40 years. In this new tour, we'll explore the rich biodiversity at the Gardens, learn about its value, and discover how you can help protect it in your communities.
