Environmental

Science

Presented by: Abigail Atiwag

Environmental science is an interdisciplinary field that combines elements of biology, chemistry, physics, geology, geography, and other disciplines to study the environment and address environmental issues. It focuses on understanding the interactions between natural systems, human activities, and the environment's health and sustainability. Here are key topics in environmental science:

Environmental Systems

Ecosystems : Study of ecological communities, energy flow, nutrient cycling, trophic levels, biodiversity, ecological succession, and ecosystem services (e.g., pollination, water purification, carbon sequestration).

Environmental Chemistry

Chemical composition of the environment : Air pollutants (e.g., greenhouse gases, particulate matter, ozone), water pollutants (e.g., heavy metals, pesticides, nutrients), soil contaminants, and sources of pollution (e.g., industrial emissions, agricultural runoff, waste disposal).

Environmental Biology

Ecological interactions : Species interactions (e.g., competition, predation, symbiosis), population dynamics, community structure, habitat loss, invasive species, and conservation biology.

Environmental Biology

Conservation genetics : Genetic diversity, genetic adaptation, genetic conservation strategies, endangered species management, and genetic techniques in conservation biology.

Climate and Atmospheric Science

Atmospheric processes : Atmospheric circulation, weather

patterns, atmospheric composition (e.g., gases, aerosols),

air quality, acid rain, ozone depletion, and air pollution

control measures.

Hydrology and Water Resources

Water cycle : Processes of evaporation, condensation, precipitation, infiltration, runoff, and groundwater recharge.

Geology and Earth Science

Geologic processes : Plate tectonics, earthquakes, volcanic activity, erosion, sedimentation, soil formation, and geological hazards (e.g., landslides, tsunamis).

Geology and Earth Science

Geological resources : Mineral resources, fossil fuels, renewable energy sources (e.g., solar, wind, hydroelectric), mining impacts, resource depletion, and sustainable resource management.

Environmental Policy

and Management

Environmental impact assessment (EIA) : Assessment of potential environmental impacts of projects, policies, and developments, mitigation measures, and sustainable development planning.

Environmental Policy

and Management

Environmental management : Waste management, pollution control, conservation strategies, sustainable land use planning, environmental education, and public awareness campaigns.
