profesor question: does man need protection from himself?

Does man need protection from himself?
In the book Prodigal Summer, it is very clear that man needs protection from himself. Tobacco was the main crop grown in Zebulon County, as we all know tobacco and its products give cancer. The tobacco was not just affecting the people who bought cigarettes, cigar and nicotine gums but also affects the farmers and the people in the community. Tobacco is providing an income for the farmers but is far moor damage than good. If man is not protected from himself he will just be like a donkey following a carrot to his grave.
The Sevin powder used by Garnet Walker to rid his chestnut trees of parasite is believed to has help killed his wife by giving her lungs cancer even though neither she nor he had ever smoked. This was a lose-lose situation in modern farming because the chemical that is used to kill what we call parasites also kill other things in nature, hence, producing more of what man is trying to get rid of. Non- organic farmers are blinded to this fact and must be protected from self-destructing.
The chemicals from these chemo-farming pollute the under ground water system that the same people and many others get their drinking water. They are literally drinking pesticides in a diluted form. The chemicals also left residue on the plants and food they claim to treat, combining with the chemical laced water raked havoc on its consumers. If man is not, at this point, saved from himself, the world will be a miserable place.
The question from now on is not “Does man need protection from himself?” but who can and will protect man from himself?
