Question
What are the benefits of using clean energy sources to control air pollution?
- Cutting down the ozone depletion
- Lesser emission of carbon
- Both A and B
- Increase the quantity of water in the rivers
Hint:
Clean energy sources produce less Green house gases.
The correct answer is: Both A and B
Cutting down the ozone depletion, and Lesser emission of carbon are the benefits of using clean energy sources to control air pollution.
- Our energy sources play a vital role in air quality, from heating, cooling, and powering our homes and businesses to transportation. Burning fossil fuels such as coal, natural gas, gasoline, and diesel create toxic air pollution and release greenhouse gases that cause climate change. Climate change not only directly jeopardizes our health, but it also makes it more difficult to eliminate harmful ozone and particulate pollution.
- Human activities overload our atmosphere with carbon dioxide and other global warming emissions. These gases act like blankets, trapping heat. The result is a web of significant and detrimental impacts, from stronger and more frequent storms to droughts, sea level rise, and extinction.
