Everywhere we turn there they are; in the food we eat, the air we breathe and even on our cute pet pugs; no, I am not talking about the cast from High School Musical. I speak of parasites. As long as nature has evolved, parasites have evolved along with it.
So exactly what is a parasite, asks a WikiAnswers user.
A parasite is an organism that benefits from a close, prolonged relationship with another organism – its host – while the host organism is harmed. Examples include tapeworms in the human intestine, mites on a parrot or fungus infesting a maple tree. In all these cases, one species is sucking the life force out of another species.
The answer, my fellow humans, is yes. Scientifically referred to as direct intraspecific kleptoparasitism, this type of parasitism is rare in nature but an all too common phenomenon amongst our own kind. Think about those hardworking parents, waiting with outstretched arms, to embrace their Xbox-playing, beer-chugging, Tila-Tequila-quoting, recent college graduates. These parents are so happy and giving, only to find, five years down the line, that their child has no intention of leaving the house with the couch, free laundry service and magical fridge that autofills each week.
What can we do to remedy this problem?
In nature, the rule is kill or be killed: the host or parasite will eventually die. Luckily, tapeworms are destroyed by one prescribed pill from the doctor, parrots get treated with a lethal-mite shampoo and fungus on a maple tree is attacked by toxins in the leaves.
People parasites are, however, different. There is no shampoo that gets your son a job interview or special toxin that oozes out of the Xbox controller when it’s been handled too long.
