    Study Notes

    Impacts of Biodiversity Loss

    • Humans benefit greatly from biodiversity, relying on resources like water, food, and medicine.
    • Edward O. Wilson predicted a yearly loss of approximately 27,000 species, primarily due to ecosystem destruction, especially in tropical forests and grasslands.
    • Past mass extinctions were largely caused by catastrophic events, but the current threat is human-caused ecosystem disruption.
    • Population growth, industrialization, agriculture, mining, fishing, deforestation, pollution, and exploitation of biodiversity contribute to habitat destruction.
    • Introduction of exotic species, poaching, and technological advancements also harm biodiversity.
    • Deforestation accelerates biodiversity loss as it removes natural habitats.
    • Technology has both positive and negative effects on biodiversity. Clearing forests for infrastructure, agriculture, and resources releases carbon dioxide and other pollutants.
    • Biodiversity loss can contribute to climate change, pest infestations, and disease outbreaks.
    • Intensive agriculture and mining damage the environment and cause pollution and eutrophication.
    • The 14th World Congress of Public Health highlighted the link between biodiversity and human health.

    Pressures on Biodiversity

    • Habitat destruction: Human activities rapidly alter ecosystems, decreasing species diversity and causing extinctions. Logging and conversion of forests are key examples.
    • Invasive alien species: Non-native species often outcompete native species for resources, impacting diversity.
    • High population density and growth rates: Increased demand for resources leads to habitat loss.
    • Climate change: Climate change is a major driver of biodiversity loss, impacting coral reefs and other ecosystems.
    • Illegal wildlife trade: The hunting of animals for profit reduces biodiversity.
    • Lack of knowledge about biodiversity: Limited public awareness hinders conservation efforts.
    • Inadequate enforcement of environmental laws: Current regulations are not always effectively enforced.
    • Failure to value the environment: The crucial services ecosystems provide (valued at $33 trillion annually) are often outside of market valuation.
