Benefits to Man – Food, Drink and Agriculture

  • Biodiversity is important for agriculture as it provides not only plants and animals for human consumption, but also a source of genetic diversity for plant and animal breeders.
  • Climate change is altering the agricultural practices of many countries and new varieties of plants and even new species will be required for survival in these ever changing conditions.
  • Genetic diversity also provides a source of new variation to cater for changing fashions or an increase in the nutritional value of food e.g. low fat milk and high protein content cereal crops.
  • These genes can also be introduced into organisms by genetic engineering techniques.
