Answer 2

Answer:

By burning fossil fuels, humans contribute significantly to air pollution.

Explanation:

• The vapors released when gasoline evaporates, as well as the chemicals formed when gasoline is burned, contribute to air pollution (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons).  
• When gasoline is burned, carbon dioxide is created, which is a greenhouse gas.
• Nitrogen oxides are released into the atmosphere when fossil fuels are burned, contributing to smog and acid rain.
• The most common nitrogen-related compounds released into the air as a result of human activity are nitrogen oxides.
• More than any other energy source, coal pollutes the environment the most.
• Although coal generates only  44% of US electricity, it is responsible for 80% of carbon emissions from power plants. Coal combustion is responsible for soot, smog, acid rain, global warming, and carbon emissions.
• Global carbon emissions from fossil fuels have risen significantly since 1900. Since 1970, CO2 emissions have climbed by more than 90%, with fossil fuel combustion and industrial operations accounting for over 78 percent of the total increase in greenhouse gas emissions between 1970 and 2011.
