Coal-burning factories and increased automobile usage has caused the most significant increase in which of these?(1 point) Responses

There are several possible responses to this question, and the most accurate answer may depend on the specific context. However, some potential responses could be:

- Air pollution: Coal-burning factories and increased automobile usage can release pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, leading to increased air pollution.
- Greenhouse gas emissions: Both coal-burning factories and increased automobile usage contribute to the release of carbon dioxide and other greenhouse gases, which are driving climate change.
- Respiratory diseases: The pollutants emitted from coal-burning factories and cars can contribute to the development or exacerbation of respiratory diseases such as asthma and chronic obstructive pulmonary disease.
- Acid rain: Coal-burning factories can release sulfur dioxide and nitrogen oxides, which can react with water vapor in the atmosphere to form acidic compounds. These compounds can then fall to the ground as acid rain, potentially harming ecosystems and infrastructure.
- Traffic congestion: Increased automobile usage can lead to more traffic congestion, which can have negative impacts on productivity, travel times, and overall quality of life in urban areas.
