What sort of pollution is responsible for global warming?

A) water
B) light
C) groundwater
D) air

Global warming is primarily caused by the increasing amount of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. These gases trap heat from the sun and prevent it from escaping into space, leading to an increase in the Earth's overall temperature. These greenhouse gases are primarily produced by human activities, such as burning fossil fuels for energy and transportation. Therefore, air pollution is the main source of pollution responsible for global warming.
