1. Natural Pest Extermination
Most bats feed on insects and have been documented eating bugs that attack food crops, such as beans, rice, corn, sugarcane, and coffee. They also eat insects that attack cotton crops. Each bat can eat thousands of insects in a single night, significantly helping to keep the pest population under control. Because of bats, farmers do not have to use as many chemical pesticides on their crops. Savings on pest control due to bats have been estimated between $3.7 billion and $54 billion per year. Less pesticide use also means fewer chemicals polluting the environment, which is good for the planet and every living thing on it.2. Echolocation
Bats' big ears and turned-up noses can be off-putting to some people, but their ugly-cute appearance actually serves a very valuable purpose. Contrary to folklore, bats are not blind, but because they are nocturnal, they rely on their ears more than their eyes to navigate and find food in the dark. Bats use a technique called echolocation, which is sort of like natural sonar. They generate extremely high-pitched noises, most of which are beyond the normal human hearing range. The sound waves bounce off objects and echo back to the bat. Bats' unique facial features help them to perceive the sound waves, and the information they receive gives them the exact location of the food they are trying to catch or the obstacles they are trying to avoid.
