While waiting at an airport, neil campbell once overheard this claim: "it’s paranoid and ignorant to worry about industry or agriculture contaminating the environment with their chemical wastes. after all, this stuff is just made of the same atoms that were already present in our environment." drawing on your knowledge of electron distribution, bonding, and emergent properties (see concept 1.1), write a short essay (100–150 words) countering this argument
