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.
