Biological diversity refers to the variety of life that exists in our world. Every organism, big or small, plays a role — yet our world and region are becoming less diverse. Partly due to human activities, the rate of extinction is accelerating rapidly and thousands of species of animals are already classified as “threatened” or “endangered.” What we do now, and how we choose to do it, matters a lot to other creatures — and to ourselves. Construction of homes and buildings; the strain on natural resources for food, clothing, fuel and all the stuff we consume; and the waste we produce — contribute to the main cause of animal species loss.
