Ecotourism refers to a type of tourism that is sustainable and responsible. Although there have been many cases in which people are not responsible and actually cause harm to the environment, usually ecotourism could be extremely beneficial for both nature and the economy.
Ecotourism motivates people to care for nature, to appreciate fauna in the wild - instead of trapped in swimming pools or in a circus, to get to know people from other cultures such as tribes and indigenous groups and their lifestyles. Ecotouristic companies provide thousands of jobs and their tours also contribute significantly to the economy of a country. For instance, responsible whale watching provides millions of dollars yearly to the economy of Mexico. People are able to observe whales in their natural habitat, to listen to their vocalizations, and observe their natural undisturbed behavior.
