    Study Notes

    Environmental Concepts and Principles

    • "Environment" originates from the French word "environ," meaning "surrounding."
    • Surroundings encompass biotic (living) and abiotic (non-living) factors in an ecosystem.
    • Biotic factors include producers (e.g., plants), consumers (e.g., animals), and decomposers (e.g., beetles, worms, bacteria).
    • Decomposers recycle waste from producers and consumers.
    • Abiotic factors consist of chemical elements (e.g., water, soil, rocks) and physical conditions (e.g., temperature, weather) that influence ecosystems.

    Major Components of the Environment

    • Hydrosphere: All water bodies, including lakes, rivers, and oceans; operates through the hydrological cycle.
    • Lithosphere: Comprises the Earth's crust and its layers—crust, mantle, core; includes soil, rocks, and mountains.
    • Atmosphere: A gaseous layer protecting Earth; contains oxygen and carbon dioxide; consists of five layers: troposphere, stratosphere, mesosphere, thermosphere, exosphere.
    • Biosphere: The life layer encompassing all organisms and their interactions with air and water.

    Seven Environmental Principles

    • Nature Knows Best: Humans must align with natural processes for sustainable resource supply.
    • All Forms of Life Are Important: Each organism has a unique role; all are essential for ecosystem balance.
    • Everything Is Connected: Ecosystem components are interdependent; disturbances can cause imbalances.
    • Everything Changes: Change is constant; environmental conditions evolve over time; human activities can exacerbate these changes.
    • Everything Must Go Somewhere Else: Waste and emissions remain in the environment and can affect ecosystems in various ways.
    • Ours Is a Finite Earth: Resources are limited; renewable resources can be depleted if mismanaged, unlike non-renewable resources that cannot be replenished.
    • Nature Is Beautiful; We Are Stewards: Humans are responsible for caring for the environment, as destruction threatens survival.

    Environmental Law

    • Encompasses treaties, statutes, and regulations addressing human impact on the environment.
    • Serves as a foundation for sustainability amid increasing environmental challenges.

    Major Environmental Laws in the Philippines

    • Environmental Impact Statement (EIS) of 1978: Introduced by Presidential Decree 1586 to balance socio-economic development with environmental protection.
    • Toxic Substances, Hazardous and Nuclear Waste Control Act of 1990: Regulates hazardous chemicals and prohibits dangerous waste entry into the Philippines.
    • Philippine Clean Air Act of 1999: Aims to maintain clean air and adhere to national air quality standards.
    • Ecological Solid Waste Management Act of 2000: Establishes a comprehensive waste management program to protect public health and the environment.
    • Philippine Clean Water Act of 2004: Protects water bodies from pollution and promotes an integrated pollution prevention strategy.
    • Environmental Awareness and Education Act of 2008: Mandates integration of environmental education into school curriculums across all levels to promote awareness.
