Answers

Answer 1

Answer:

Answer:

antarctica

Explanation

Since the Industrial Revolution period, humans have contributed to the destruction of the Ozone Layer. The release of carbon dioxide, nitric and nitrous oxides, and chlorofluorocarbons in the atmosphere make it impossible to renew ozone, allowing ultraviolet rays to penetrate the planet's surface with greater intensity.

In 1987, researchers first observed the existence of a large hole in the Ozone Layer in the Antarctic area. From then on, several surveys concluded that the ozone level has been decreasing in other parts of the planet.

Answer 2
