Maintaining biodiversity - Positive human impacts on biodiversity

Areas like tropical rainforests have millions of different species and are very biodiverse. Other areas like the Polar Regions have far fewer species and are less biodiverse.

The increase in the human population and waste it produces, deforestation, peat bog destruction and global warming are all reducing biodiversity. Conservation helps reverse this. Conservation is the preservation of ecosystems and the organisms that live within them.

Scientists and concerned members of the public help maintain biodiversity by:

  • breeding programs to help preserve endangered species, like the panda
  • protection and development of new endangered habitats, often by making National Parks
  • replanting hedgerows because there is higher biodiversity in them than the fields they surround
  • reducing deforestation and the release of greenhouse gases
  • reforestation planting trees to replace those cut down
  • recycling rather than dumping waste in landfill sites

Nicola Hallot from Knowsley Safari Park talks about the endangered animals at Knowsley including Père David's deer, Bactrian camel and scimitar-horned oryx. She also explains how zoos and safari parks across Europe work together to maintain biodiversity
