Air Pollution to Property
Air pollution isn't just bad for people, plants, and animals. It's even bad for buildings and other big structures you see outside, like statues and monuments. The chemicals in air pollution eat away at the stone the buildings are made out of and can cause cracks in them. It can also make them look dirty. When it rains, air pollution in the rain can ruin the paint on houses.
It costs a lot to fix a building once air pollution has harmed it, especially if it's a very old building. Luckily, there is a place called the National Center for Preservation Technology & Training that is studying the problem and trying to fix buildings that have been damaged by air pollution.
