Biodiversity is essential to the resiliency of ecosystems, yet part of the human impact on the planet has been a drastic reduction in biodiversity. The change is taking place all over the world; yet the most rapid changes are taking place in developing countries. In this Discussion, you will address the importance of biodiversity, the causes of biodiversity loss, and what is being done about it.
