How Are Rats Helpful to Humans?
WouterRats are useful in many ways. For instance, they eat plants, especially seeds, and transport them back to their nests. Sometimes they transport seeds many miles. This way, they can help plants grow. However, most people do not give rats credit for having a mind. They also carry a wide variety of diseases that are harmful to humans.
Rats have been shown to be highly empathic. In a recent study, they even helped fellow rats tread water, which is a sign that they can sense other rats’ pain and are willing to help. They are also known to recognize people by their names and respond to their calls. In addition, they like a wide variety of foods, and they defend their nests vigorously.
Moreover, rats are responsible for the transmission of more than 60 human diseases. As a result, the burden of rat-borne diseases on the health systems of developing countries is significant. Furthermore, these diseases often go undiagnosed, because the symptoms of rat-borne diseases are not easily distinguishable from those of other diseases. Therefore, the true burden of rat-borne diseases on human health is probably far higher than that currently accepted by researchers and clinicians.
Another way rats can help humans is by detecting mines. Their excellent sense of smell and memory make them excellent detectors. They also know where to go, and can memorize landmarks. Even if they have poor eyesight, they never forget where they are. As a result, they can help police officers locate mines.
