Biodiversity is the number of diffeent species in a particular area.
Biodiversity is important because it leads to stable ecosystems. Ecosystems help to regulate the amosphere, regulate water supply, regulate nutrient cycles and provide fertile soil. This means biodiversity is important for food, industrial materials, medicines and human well being.
Biodiversity is at risk because more and more species are becoming extinct due to habitat loss. Habitats are being destroyed due to building, quarrying, dumping rubbish and agriculture. In the last 50 years the population of animal has dropped by 60%.
Biodiversity is being protected by:
CITES (agreement to prevent trade in endagered species)
SSSI (protecting sites of special scientific intrest)
Captive breeding programs and seed banks
National parks and local biodiversity conservation schemes
