Maintaining biodiversity

Key ideas1 of 3

Ways people can help

Breeding programmes can increase numbers of endangered species. Protecting rare habitats and restoring damaged ones preserves the conditions organisms need. Reintroducing field margins and hedgerows provides food and shelter around fields with one crop. Recycling materials reduces the resources extracted and the waste sent to landfill. Some governments also act to reduce deforestation and carbon dioxide emissions. These five approaches tackle different pressures, so several may be needed together.

Conservation through endangered species breeding, habitat protection, field margins and hedgerows, and recycling.
