Why is biodiversity important?
-New medicines may be discovered
- Preserve food chains and keep ecosystems stable
Maintain interdependence
Maintain the right physical environment for each other
Economic, produce food material for example
Ethical, all species have a right to survive
Aesthetic
Why the reduction in biodiversity?
Monoculture
Deforestation
Human pollution (air, water, soil)
Land use
Protecting biodiversity
Breeding programmes for endangered species
Protection and regeneration of rare habitats.
Reintroduction of field margins and hedgerows.
Reduction of deforestation and carbon dioxide emissions.
Recycling resources.
