Final answer:
One possible effect of air pollution is global climate change, which can cause changes in weather patterns and affect agricultural outputs and energy needs.
Step-by-step explanation:
One possible effect of air pollution is global climate change. Gases such as carbon dioxide released into the atmosphere from burning fossil fuels contribute to the greenhouse effect and raise the temperature of the Earth's surface. Increased carbon dioxide and greenhouse gases can cause changes in weather patterns, precipitation patterns, and alter weather conditions, which in turn can impact agricultural outputs and influence energy needs.
