Step 1
Step 2
Explain how one of the areas you have identified has a negative impact.
Answer
Burning fossil fuels has a significant negative impact on the environment. This activity leads to the release of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere, which contribute to global warming and climate change. The combustion of fossil fuels can also lead to acid rain, which damages ecosystems, forests, and water sources.
Step 3
Step 4
Explain how one of the areas you have identified has a positive impact.
