Answers
Answer:
What are the main disadvantages of fossil fuels?
Fossil fuels have been used for centuries to generate power, but there are many disadvantages associated with their use:
Fossil fuels pollute the environment
Fossil fuels are non-renewable and unsustainable
Drilling for fossil fuels is a dangerous process
What is a fossil fuel?
The term “fossil fuel” refers to a natural fuel source that was formed in the geological past from the remains of living organisms. Fossil fuels like coal, oil, and natural gas come from the remains of ancient plants and animals that were buried for millions of years.
The conditions that the remains were under over time (such as pressure and temperature) play a part in the fossil fuel they became. For example, coal is primarily formed from the remains of land plants that have been compressed and heated.
Humans access fossil fuels today by drilling and mining into the earth to extract them from rocks and geologic formations.
Fossil fuels have several drawbacks
Although we have relied on fossil fuels to power our society for a long time, there are several disadvantages to the continued use of these types of outdated energy sources.
Fossil fuels pollute
If you have ever driven by a factory or power plant and seen smoke coming out of the top, you’re seeing fossil fuel pollution first-hand. Fossil fuels need to be burned to release the energy stored in them, which leads to smoke and gases being pumped into the air. Unfortunately, burning fossil fuels releases harmful particles and greenhouse gases into the atmosphere, resulting in adverse effects for humans and the earth as a whole.
Burning coal, for example, releases toxic particles like sulfur dioxide and heavy metals into the atmosphere. These compounds lead to many serious side effects, such as acid rain and respiratory damage in humans. Pollutants from the burning of fossil fuels have been linked to diseases like cancer and asthma in several scientific studies.
The particles released from burning fossil fuels also have negative effects for our planet as a whole. You’ve probably heard that fossil fuels contribute to climate change, and that contribution comes directly from the particles that are put into the atmosphere when they are burned. Compounds like carbon dioxide and methane enter our atmosphere and trap heat from the sun, which has lead to a continuous rise in average global temperatures since the early 1900s. Rising temperatures can lead to everything from natural habitat destruction to sea level rise.
