We are living in the age of humans, a time referred to by many as the Anthropocene. Our species has caused huge changes on our planet, including global warming, ocean acidification, and habitat destruction.
Earth's ecology is in a critical state. But we have the tools to understand what is happening, and what needs to be done.
The issues explained
How have humans changed the planet? And why does it matter? Let Museum scientists take you through the facts.
Biodiversity is the incredible variety and volume of life on Earth, and the habitats and ecosystems the support it. It allows us all to live healthy lives.
What nature does for us
Photos from the Wildlife Photographer of the Year competition will remind you of what an extraordinarily beautiful world we're fighting to protect.
Why we're losing biodiversity
Humans have been around for a very short period of time - but we have still managed to cause a lot of damage. Our actions have disrupted the balance of life on Earth, through:
