Current agricultural practices have reduced the amount of methane in the atmosphere.

Carbon dioxide and methane result from both natural and human sources.

Which of the following is an example of a mobile source of air pollution? Emissions from the manufacturing plant in town are contributing to a number of respiratory diseases. Wildfires burning within 50 mi of a city cause the air quality to worsen 10 times. The pollution from power plants is estimated to kill about 13,000 people in the United States each year. Freight trains release soot into the air, contaminating the surrounding neighborhoods.

Freight trains release soot into the air, contaminating the surrounding neighborhoods.

Which of the following is an effect of smog? Increased rates of skin cancer Trapped solar radiation in the atmosphere Damaged soil and root systems Increased respiratory diseases

Increased respiratory diseases

Select the TRUE statement about the Energy Policy Act of 1992. It required the federal government to list stationary or mobile source pollutants that could endanger public health. It established goals for greenhouse gas reductions and measures for funding research in alternative fuels. It established a reserve of oil in the United States in order to prevent gasoline shortages. It required the federal government to assess the environmental impacts of any government action or project.

It established goals for greenhouse gas reductions and measures for funding research in alternative fuels.

Efforts to address the amount of water used by humans are part of the sustainability movement. Choose the item that is NOT a goal for sustaining water on Earth. Limit the amount of available water Harvest rainwater Find new ways to store water Convert sea water into fresh water

Limit the amount of available water

What did the Clean Air Act of 1970 require the Environmental Protection Agency (EPA) to do? List likely dangerous pollutants emitted from stationary and mobile sources Establish ways to increase public awareness of air pollution Name known pollutants and set up programs to monitor their use Create limits and regulations for indoor pollution sources

List likely dangerous pollutants emitted from stationary and mobile sources

Choose the statement that is NOT true regarding outdoor air pollution sources in the United States. Approximately half of man-made air pollution emissions come from stationary sources. Natural sources of air pollution, such as forest fires and volcanoes, account for the majority of chlorofluorocarbon emissions. Highway vehicles and other mobile sources contribute about 60% of national carbon monoxide emissions. Power plants contribute the majority of the sulfur dioxide in the atmosphere.

Natural sources of air pollution, such as forest fires and volcanoes, account for the majority of chlorofluorocarbon emissions.

Choose the statement about the Kyoto Protocol that is FALSE. The agreement would only slightly reduce climate change impacts, but it was seen as a start. The Kyoto Protocol has been in force in the United States since 2012. In 1997, many U.N. countries agreed to reduce greenhouse gases. To track progress, emphasis was placed on improvement methods and emissions data.

The Kyoto Protocol has been in force in the United States since 2012.

Choose the statement about renewable and nonrenewable energy sources that is NOT true. New technologies promise future increases in the use of renewable energy sources. Renewable energy creates little or no waste and has few negative environmental impacts. Most nonrenewable energy sources can be renewed, but it takes thousands to millions of years for them to form. There has been little to no recent growth in renewable energy use because of a lack of environmental concerns with the use of fossil fuels.
