Answer 1

Two major environmental issues facing the world today are Global warming and ozone depletion.

Explanation:

Global warming and ozone depletion are two key environmental concerns that the globe faces today.

The phenomena of sustained increases in global temperature caused by pollution and deforestation are referred to as global warming. Greenhouse gas emissions, especially carbon dioxide, are to blame. Carbon dioxide levels rise, raising the earth's surface temperature and hastening the melting of polar ice. As a result, sea levels are rising. As a result of the disrupted ecological balance, natural disasters are becoming more frequent, posing a risk to human life.

Ozone serves as a protective layer over the earth's surface, which is critical for life to exist. It shields the earth's surface from damaging ultraviolet radiation. However, of days, its depletion is a global problem. This is caused to an overabundance of the substance.
