Answer:
Ozone depletion means that more of the sun's rays can reach earth. One particular troublesome ray is UVB radiation. It has many harmful effects on humans which include:
- DNA damage
- Melanoma
- Other skin cancers.
- Cataracts
- Immune system problems.
Even when humans are not affected directly, we are indirectly affected by the planet being affected. For instance, ozone damage leads to less agricultural productivity as well as adverse effects on aquatic life. Humans rely on both of these for food so ozone depletion is targeting our food sources as well.
