    Study Notes

    Human Activities and Extinction

    • Habitat loss is widely considered the most significant factor contributing to animal extinction. This includes activities like deforestation, mining, and urbanization.
    • Pollution poses a serious threat to wildlife by contaminating ecosystems through industrial discharge, agricultural runoff, and plastic waste.
    • Climate change accelerates the extinction rate of species by altering habitats, increasing the frequency of extreme weather events, and disrupting food chains.
    • Overexploitation of wildlife can lead to population declines and extinction, particularly through activities like hunting, fishing, and trading of endangered species.
    • Invasive species can outcompete native species for resources, introduce diseases, and alter habitats, contributing to population declines and extinction.
    • Habitat fragmentation can isolate wildlife populations, reduce genetic diversity, and make them more vulnerable to extinction.
    • Illegal wildlife trade threatens numerous species with extinction due to the demand for exotic pets, traditional medicines, and luxury goods.
    • Pollution poses a significant threat to many species by altering habitats and exacerbating existing threats.

    Solutions and Mitigation

    • Reducing greenhouse gas emissions and implementing adaptation strategies is crucial for safeguarding wildlife against the threats of climate change.
    • Protecting natural habitats can help prevent habitat loss and fragmentation, which are crucial for safeguarding wild species from extinction.
