I was surfing around the other day and came across a guy citing the existence of the Guinea Worm as a sign that God really doesnt care about us.
The guinea worm is a parasitic organism that is eaten by water fleas.
They in turn, are consumed by human beings from contaminated water
The stomach acids kill the water flea and the parasite is released into the human intestine.
The parasite grows and within a year it potrudes out of the skin so it can release eggs. (at this point it can get up to 3 feet in length).
The parasite is extremely difficult to remove and the only effective method is to wrap the potruding portions around a stick and pull it out an inch at a time for several weeks. This process is long and painful.
I think the worse/most interesting thing about this parasites is that it ONLY effects humans.
It was as if it was specifically designed to hurt humans (or if you dont believe in god, specifically evolved to use humans).
