    Study Notes

    Biodiversity

    • Biodiversity is the variety of life on Earth
    • Humans depend on biodiversity for resources like food, raw materials, and medicine
    • All living things in a habitat are interdependent and interact with each other to form an ecosystem

    The Importance of Biodiversity

    • Biodiversity is crucial for maintaining a sustainable ecosystem

    Reduction in Biodiversity

    • Many human activities threaten biodiversity, including:
      • Destruction of habitats
      • Overexploitation
      • Pollution

    Endangered Species

    • Endangered species are at risk of becoming extinct
    • Overexploitation, habitat destruction, and pollution all contribute to species becoming endangered

    Conservation

    • Conservation efforts are essential for protecting the environment and Earth's biodiversity
    • We can help conserve biodiversity by:
      • Protecting wildlife and their habitats
      • Supporting conservation programs
      • Practicing the 3Rs principle (Reduce, Reuse, Recycle)
      • Using resources sustainably

    The 3Rs Principle

    • Reduce: Minimize our consumption
    • Reuse: Find alternative uses for items before discarding
    • Recycle: Repurpose waste materials
