Because the wind may carry the pollution from elsewhere

The UK has problems with acid rain and pollution in big cities. Climate change will cause most of London to flood. There is also water pollution problems.
For the air, pollution can cause acid rain and hazes that cause medical problems. For animals, trash and oil can kill or strangle them. For us, we should stop pollution and save our planet. Stop Pollution. Save the Earth.
acid rain is an example of what air pollution
"Acid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition. Is it made by atmospheric pollution rich in sulfur dioxide and nitrogen oxides.
Air pollution is generally acidic in nature, involving nitrogen and sulfur compounds that produce acid when dissolved in water, so when they wash out of the air in the rain, the result is known as acid rain. When acid rain gets into rivers, they acidify. This is harmful to fish.
acid rain is the result of air pollution
I don't think there is a chemical in a cloud because it is a droplets water (H2O) however when pollution mixes with the rain it produce an acid rain containing Sulfuric Acid (HSO4)
Pollution. More specifically, "Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids."
acid rain; SO2, i.e. sulfur dioxide, reacts with water to produce H2SO3, or sulfurous acid, which then reacts with oxygen to form sulphuric acid (H2SO4), and dissolves in rain to fall as acid rain
