The primary concern of using coal energy is that burning coal contributes to acid rain and global warming. Here's why:
1. When coal is burned to produce energy, it releases pollutants such as sulfur dioxide and nitrogen oxides into the atmosphere.
2. These pollutants can react with water vapor in the air to form acid rain, which can damage forests, lakes, and buildings.
3. Additionally, burning coal releases carbon dioxide, a greenhouse gas that contributes to global warming and climate change.
4. Therefore, the main environmental impact of using coal energy is the negative effects it has on the environment through acid rain and its contribution to global warming.
