Answer:
When fossil fuels are bumed they release toxic gases into the air that cause pollution and increase global warming
Explanation:
Fossil fuels are fuels which were formed from the remains of dead plants and animals buried underground for millions of years ago, which anaerobic bacteria and the high pressure and heat underground transformed into the fuels as we know them today. Fossil fuels are mainly hydrocarbons and they include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
The combustion of fossils fuels today provides the majority of the energy used by man worldwide. Energy from fossil fuels power our homes and industries, cars, trains aeroplanes, etc.
However, the combustion of fossil fuels impacts the environment negatively. Fossil fuels produce carbon dioxide as end-products when burnt which pollutes the airanspd is a major greenhouse gas contributing to global warming.
Combustion of fossil fuels releases acidic gases such as sulfur dioxide, nitrogen dioxide to the environment resulting in acid rains as well as many unpredictable and negative changes in the environment.
