    Study Notes

    Biodiversity Overview

    • Biodiversity is a critical component of Earth's ecosystems, impacting various aspects of human life and well-being
    • Extensive loss of biodiversity is considered a major environmental concern, exceeding an environmental emergency
    • The loss of biodiversity is driven by human activities
    • Human society is under urgent threat due to declining biodiversity and Earth's natural life
    • The variety of life on Earth is vast and includes species such as fungi, bacteria, plants, animals, and protists
    • Biodiversity forms a crucial foundation for essential ecosystem services, contributing to human well-being

    Defining Biodiversity

    • Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems.
    • This diversity encompasses ecological complexes and variations within species and across different ecosystems

    Impacts of Biodiversity

    • Biodiversity is crucial for human nutrition, ensuring the sustainable productivity of soils, and providing genetic resources of agricultural crops, livestock, and marine species
    • Sufficient access to nutritious foods is essential for health
    • Food variety is vital for micronutrient availability in the diet
    • Natural systems like wetlands help maintain water quality, filtering contaminants

    Threats to Biodiversity

    • The major causes are habitat loss/destruction and alterations within ecosystems
    • Overexploitation of resources
    • Pollution and contamination
    • Global climate change
    • Major threats arise from human activities involving land use conversions and economic benefits.

    Benefits of Biodiversity

    • Soil quality
    • Water quality
    • Waste removal
    • Pollination and seed dispersal
    • Medicine
    • Ecotourism

    Biodiversity in Specific Locations

    • In Asia, grasslands have been degraded by overuse, converting them for other land uses.
    • 25% of the region's endemic species are threatened.
    • Protected areas are increasing in some areas
    • The Philippines is a mega-biodiverse country, with high levels of plant and animal species endemism.
    • 70-80% of the world's plant and animal species are located in the location.
    • The country plays a major role in global biodiversity.
    • There are concerns and efforts toward conservation.
