Uses of Biodiversity

Importance of Biodiversity

• Biodiversity as a Natural Resource

  • Biodiversity provides essential resources like food, medicines, and industrial products.
  • It supports ecological balance by fostering diverse ecosystems.

• Pharmaceutical Contributions

  • Many pharmaceuticals derive from plant substances.
  • Examples:
    • Opium Poppy (Papaver somniferum) : Used for pain relief and sedation.
    • Periwinkle (Catharanthus roseus) : Produces anti-cancer drugs like vinblastine and vincristine.

• Anti-Cancer Drugs

  • Taxol: Major breakthrough in cancer treatment.
  • Vinblastine & Vincristine: Used for Hodgkin's disease and leukemia.

Traditional and Modern Applications

• Ethnomedicines

  • Traditional knowledge of plant-based medicines is crucial for modern drug development.
  • Thousands of species have potential therapeutic uses.

• Botanochemicals

  • Plant-derived chemicals used in various industries beyond pharmaceuticals.
  • Include oils, gums, and resins.

Genetic and Agricultural Value
