- Effects of Human Activities & Sustainability
- Endangered Species
- Biodiversity
- The variety of species on Earth
- Causes for the decrease in biodiversity and extinction
- Loss of habitat
- E.G. Deforestation
- Over hunting by humans
- Competition from newly introduced species
- E.G. Alien species
- Pollution
- E.G. Oil slicks/ air pollution
- Draining wetlands
- Loss of hedgerows
- Loss of habitat
- Biodiversity
- Conservation of Species
- Conservation = the maintenance of the bio-sphere and the enhance-ment of biodiversity
- Nature Reserves
- SSSI - Sites of Special Scientific Interest
- International co-operation on restricting trade
- Sperm banks
- Seed banks
- Captive breeding programmes
- Re-introduction programmes
- E.G. Red Kites in Wales
- Agricultural Exploitation
- Humans are dependent upon the Earth's resources for survival
- Increasing population size means more food needs to be produced
- In agriculture an increase in land use has led to conflict between production and conservation
- Over-fishing of the oceans has also caused this
- Using pesticides and fetilizers has improved crop yield
- However this has also led to the development of environmental issues
- Endangered Species
