Unit 26: Biodiversity and conservation

About this unit

From penguins to palm trees to bacteria, our planet is host to an awe-inspiring diversity of organisms. Dive deep into Earth's breathtaking biodiversity, learn why this biodiversity is in peril today, and discover what you can do to protect the species and ecosystems that support human life on Earth. This content is provided by the California Academy of Sciences.

Discover why a high diversity of species sustains ecosystems, which in turn provide important services to humans. This content is provided by the California Academy of Sciences.
Explore how life is found almost everywhere on Earth, but is not distributed evenly. And learn why the clumped distributions of species are the result of a wide variety of both natural and human-driven factors. This content is provided by the California Academy of Sciences.
Examine the local and global threats to biodiversity that are caused by human activities. Many of the negative impacts start as regional, but easily add up to affect the entire planet. This content is provided by the California Academy of Sciences.
Research, education, individual action, and public policy all have important roles to play in protecting biodiversity. That means there's a lot you, personally, can do to preserve species and ecosystems - whoever you may be, and wherever you may live! This content is provided by the California Academy of Sciences.
Learn how to recognize the genetic, ecosystem, and evolutionary levels of biodiversity. Along with species richness, these levels play crucial roles in conservation. Content provided by the California Academy of Sciences.
