The Good and the Bad of the Rat The rat is a creature with a poor reputation. This is due to the fact that rats are common opportunistic species that frequently live along side humans and cause problems, like eating food supplies and transmitting diseases like the plague. But rats have their good sides as well, and there are a number of ways that rats benefit humanity. In parts of India and Polynesia rats are commonly eaten. They are even cultivated in some places like chickens and considered a delicacy. In places where they have proliferate and people lack other food, eating rats might actually be a life saving food source for some groups of people. Due to its short life span and rapid reproduction, rats make a good subject for all kinds of scientific research. Some species have even been breed over many generations to have certain characteristics, like a susceptibility to a certain disease, that makes them ideal models for important medical studies. For every disease caused by this rodent, there are probably many more that have been cured by using them as subjects in scientific research. Rats also have an extraordinarily good sense of smell. This, along with their high intelligence, has made it possible to train them for sniffing out explosives used in land mines and even for diagnosing diseases like tuberculosis. Rats also make good pets, for those who enjoy them, and when kept as pets they are no more likely to cause disease than a dog or a cat. While we love to hate them, and their very name is sometimes used as a curse, rats have a more complicated relationship to humanity that we might like to admit. It could even be said that without rats, human life would not be what it is, for both the bad and the good.
