    Study Notes

    Environmental Science Final Assessment

    • The assessment covers various environmental science topics, including human population, carbon dioxide levels, acid rain, biodiversity, and more.

    Human Population and Carbon Dioxide Levels

    • The human population and carbon dioxide levels in the atmosphere are increasing.

    Acid Rain

    • Acid rain has severe effects in the northeastern United States, including New York State.
    • Decreasing fossil fuel use can help reduce acid rain.

    Global Warming

    • Average yearly temperatures for Earth have been increasing since 1880.
    • This change is likely due to increased burning of fossil fuels and increased carbon dioxide in the atmosphere.

    Reducing Carbon Dioxide in the Atmosphere

    • Decreasing the burning of fossil fuels can help reduce carbon dioxide in the atmosphere.

    Electricity Usage

    • The usage of electricity in the United States has increased dramatically over the past 10 years.
    • Most of this electricity is currently produced by burning fossil fuels.

    Energy Sources in the United States

    • Petroleum and natural gas together provide more than 50% of the energy needs of the United States.

    Groundwater Pollution

    • Human activities can affect groundwater, and drinking water can become polluted from unsuspected sources.

    Erosion

    • Erosion is most likely when the soil is bare and exposed to wind and rain.

    Industrial Revolution

    • The Industrial Revolution did not directly result in the overhunting of large mammals.

    Toxins in the Food Pyramid

    • Toxins such as mercury can accumulate in the tissues of organisms as we go up the food pyramid.

    Ecosystem Energy

    • The energy in most ecosystems originally comes from green plants.

    Point-Source Pollution

    • Pollution that comes from a specific site is called point-source pollution.

    Health Problems and Air Pollution

    • Asthma is a health problem directly connected to air pollution.

    Non-Renewable Energy Sources

    • Oil, coal, and gas are non-renewable energy sources.

    Tragedy of the Commons

    • The tragedy of the commons refers to when humans overuse resources in an area.

    Sustainability

    • Sustainability is a condition in which human needs are met in such a way that a population can survive indefinitely.

    Natural Resources

    • Natural resources are living and nonliving things found on Earth that people need.

    Manatees

    • Manatees are mammals that live in the warm, clear water environment of Florida's shallow rivers.
    • Human activities, such as habitat destruction and boat collisions, may lead to the extinction of manatees.

    Biodiversity

    • The loss of biodiversity is a source of concern.
    • Threats to biodiversity include habitat destruction, pollution, and climate change.
    • Supporting and reclaiming biodiversity can be achieved through conservation efforts and sustainable practices.
