The mass poisoning of humanity: an exploration of human stupidity

As human beings, we're the only species stupid enough to actually poison ourselves. As part of modern living, we create a wide variety of chemical toxins that go into the ecosystem through rivers and streams, the air, the soil and so on. Not only that, we actually synthesize toxic chemicals and then inject them directly into the food supply -- knowing full well that they are poisonous and are major contributors to the epidemic rates of chronic disease we are experiencing today.
