What type of indoor pollution should I be concerned about?

Depending on the country you live in; cause some countries still use asbetos and that causes lung cancer, and mesothelioma. In alot of homes Radon Gas can be an issue and they do sell detectors for things like radon and so on. Carbon monoxide detectors are a good thing to have especially if gas is used in the home.

Check your town because they maybe required.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
