    Study Notes

    Sustainability

    • Refers to meeting the needs of the present without compromising the ability of future generations.
    • Involves environmental stewardship, social responsibility, and economic viability.

    Two-Centered Viewpoints on People and the Environment

    • Anthropocentric: Views humans as the central concern, prioritizing human needs and benefits.
    • Ecocentric: Emphasizes the intrinsic value of all living beings and ecosystems, advocating for their protection regardless of human benefit.

    Importance of the Natural Environment

    • Provides essential resources such as air, water, and food.
    • Supports biodiversity, which is crucial for ecosystem stability and resilience.
    • Offers recreational, cultural, and spiritual benefits to communities.

    Four Ecological Services

    • Provisioning Services: Supply of resources like food, water, and raw materials.
    • Regulating Services: Control of climate, disease, and water quality through natural processes.
    • Supporting Services: Necessary processes for ecosystem functioning, such as soil formation and nutrient cycling.
    • Cultural Services: Non-material benefits such as aesthetic enjoyment and cultural identity.

    Human Impact on Ecological Services

    • Deforestation reduces provisioning and regulating services.
    • Pollution affects water quality and biodiversity, disrupting supporting services.
    • Urbanization fragments habitats, leading to the loss of cultural and ecological connections.

    Effects of Human Influence on the Environment

    • Social Effects: Displacement of communities due to environmental degradation.
    • Economic Effects: Loss of livelihoods in sectors reliant on healthy ecosystems, such as fishing and agriculture.
    • Environmental Effects: Increased pollution and loss of biodiversity, leading to ecosystem collapse.

    Ecological Footprint

    • Measurement of human demand on Earth's ecosystems, expressed in land and water area needed for resource consumption and waste absorption.
    • Calculation involves assessing resource consumption and waste production against the planet's capacity to regenerate.

    Causes of Climate Change

    • Human Causes: Fossil fuel combustion, deforestation, industrial processes, and agricultural practices increase greenhouse gas emissions.
    • Natural Causes: Volcanic eruptions and solar variations that influence Earth's climate system.

    Greenhouse Effect

    • Natural process where certain gases (GHGs) trap heat in the atmosphere, allowing Earth to maintain a suitable temperature for life.
    • Enhanced greenhouse effect occurs due to increased GHG emissions from human activities.

    Production of GHGs

    • Transportation, energy production, and industrial activities release carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
    • Agriculture, particularly livestock and rice production, significantly contributes methane emissions.

    Enhancement of the Greenhouse Effect

    • Increased fossil fuel usage in transportation and industry leads to higher CO2 levels.
    • Deforestation decreases CO2 absorption, exacerbating climate change effects.

    Evidence of Recent Global Warming

    • Rising global temperatures and increased frequency of extreme weather events.
    • Melting polar ice caps and rising sea levels indicate climatic shifts.

    Effects of Global Warming

    • Altered weather patterns threaten agricultural productivity and food security.
    • Increased flooding and droughts displace populations and disrupt ecosystems.
    • Loss of biodiversity as species struggle to adapt to rapid environmental changes.

    Strategies to Mitigate Climate Change

    • Transitioning to renewable energy sources, improving energy efficiency, and promoting sustainable land use.
    • Reforestation efforts and enhancing carbon sequestration methods.
    • International cooperation and policy frameworks to reduce GHG emissions.

    Great Pacific Garbage Patch (GPGP)

    • A large area in the North Pacific Ocean with high concentrations of plastic debris, posing a threat to marine life and ecosystems.

    Plastic Accumulation in Oceans

    • Plastics enter oceans through rivers, direct disposal, and coastal waste, leading to significant pollution.
    • Ocean currents facilitate the transport and accumulation of plastic debris in certain gyres.

    Positives and Negatives of Plastic

    • Positives: Versatile, lightweight, and durable, making it useful across various industries.
    • Negatives: Non-biodegradable, leading to long-term pollution and potential harm to wildlife.

    Impact of Plastic on Wildlife

    • Ingestion and entanglement pose serious threats to marine species, leading to injury and death.
    • Chemicals leached from plastics can disrupt hormonal functions in marine animals.

    Importance of Tourism to Developing Nations

    • Provides essential income and employment opportunities, strengthening local economies.
    • Encourages the preservation of natural environments and cultural heritage.

    Case Studies Using the W's (Who, What, Where, When, Why)

    • Analyze specific instances of environmental challenges or success stories to illustrate broader concepts.

    Strategies to Reduce Ocean Plastic

    • Promoting recycling and waste management programs in coastal communities.
    • Implementing policies to reduce single-use plastics and foster sustainable alternatives.
    • Engaging the public through education and awareness campaigns on plastic pollution.
