Q

Why is biodiversity important?

A
  1. All organisms in ecosystems depend on one another, it allows large-scale ecosystems to function and self-regulate. If biodiversity is reduce in one area, the natural balance may be destroyed elsewhere!
  2. Biodiversity allows genetic variation which we use to develop crops, livestock etc. It also allows improvement in cross-breeding and genetic engineering. This will help us cope with problems due to climate change and disease.
  3. Plant biodiversity provides potential chemicals to be produced which are important in many areas of human life, including new medicines.
