  • Biodiversity refers to the variety of all different species of organisms on Earth or within an ecosystem.
  • The term "biodiversity" combines "bio" (living) and "diversity" (variety or difference).
  • Examples of biodiversity can be observed in coastal ocean areas, including species like fish, turtles, whales, and swordfish.
  • Biodiversity is crucial because organisms depend on each other for food, shelter, and environmental maintenance, a concept known as interdependence.
  • High biodiversity contributes to more stable ecosystems by reducing the dependence of one species on another.
  • Human activities such as deforestation, mining, resource extraction, waste production, and building are reducing biodiversity.
  • The reduction in biodiversity poses significant risks to human survival as it impacts the stability and sustainability of ecosystems.
  • Efforts to halt biodiversity loss have only recently begun, indicating the need for continued and increased action to preserve biodiversity.
