Who says the proposed law has anything to do with farting?

The wording refers to something which " vitiates the atmosphere in any place so as to make it noxious to the public to the health [sic] of persons..."

There is no evidence that farting, while embarrassing, was ever bad for anybody's health. But the new law would prohibit harmful things like dumping chemicals, abandoning garbage, burning trash, etc.

It sounds to me like something we 'civilized' people expect without giving it a thought.
