Eww. That's gross. Your willing to touch that? Such thoughts seem to be common in our society, limiting what we do for sanity or other reasons that might or might not exist. A fear of the disgusting probably is not a bad thing unless it impacts life negatively and causes people to do acts that are destructive either to the individual or our environment.

People should not be afraid of their environment. They should be aware of the dangers that nature poses to ourselves, but it should be a realistic fear. We are indeed creatures of nature, painted by the same hand of god as our animal and plant friends. Gross things should not be something parodied or played up like the Discovery Channel does with their Dirty Jobs show, but instead should be what the realism of life is about.

Let's consider two areas: blood and guts (rotting or alive), manure.

Animals and people die. That's a natural part of life, and death should not be glorified or dismissed. It instead should be about a dignified process. The death of animal is different from a human, and sometimes animals have to be put down. There certainly is sanitary concerns with dead animals and the pathogens they can transmit to humans but if we follow basic procedures then we have less to worry about.

Manure and other kinds of shit. Farmers put rotted cow manure on their fields to restore the nitrogen balance to the fields. It's been going on for many years. Yet, we have controls over what the animals are fed and the process of decomposition kills most if not all of the toxins in the manure.

You shouldn't fear or be too disgusted to see natural processes taking place. We have to be wary of sanitary dangers, but at the same time we should not be fearful or disgusted by jobs that seem dirty or otherwise disgusting. Shows like the Discovery Channel's Dirty Jobs only work to reinforce stereotypes rather then make people more honest about the realities of sanitary conditions.
