The condition of the environment has no affect on its inhabitants. true or false

The answer is going to be false.

This is false. Conditions of the environment we live in can have a huge affect on us. Imagine if pollution took over your state. It would be hard to breathe, and you would most likely end up evacuating. Of like if all the crops that Farmers tend to just suddenly died because of a sudden weather change? Not only would that affect the Farmer, but also all the companies and people he would have shipped those crops to.
Hope this helps.
