Answer and Explanation:
The environmental problems caused by human exploitation of the environment have caused many problems that will harm life on earth as a whole, including human beings that will be strongly affected. Deforestation, pollution, the frequent use of fossil fuels, the release of polluting gases, among other situations, have caused an environmental change, in addition to weakening the earth's protective ozone layer, leaving the planet unprotected from the sun's rays. This, in addition to causing dermatological problems, has stimulated the existence of global warming and extreme climate changes that have strongly harmed the environment. This increases the extinction of animals and plants and impairs food production, making life on earth increasingly difficult.
