Explanation:
Most human-made air pollution comes from burning fossil fuels for transportation, electricity, and industry. Common pollutants produced by fossil fuel burning engines are carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates.
If the atmosphere gets more polluted with smoke and dust, it will eventually increase the level of harmful gases such as carbon dioxide in the Earth’s atmosphere. This rise in carbon dioxide would further result in a rise in global temperatures, thus, leading to global warming.
