Certain animals can use echolocation to build up pictures of their surroundings. This is called echolocation. How have humans used this knowledge to solve a problem?

In order to advance in science, we must use all of our resources to help, but when does this experimentation become unethical and when does it solve a problem? Animals, including bats, whales, dolphins and some bird species use echolocation to determine the location of objects using reflected sound. This gives them the ability to navigate in pitch darkness. Echolocation experiments can solve a lot of problems within humans, especially those with visual impairments.
