Question

Briefly explain depletion of ozone layer and its effects.

Answer 1

Explanation:

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole.

Effects of the ozone hole to the environment and health

For humans, direct exposure to UV rays can lead to: Skin cancer such as melanoma, basal cells or squamous cell carcinomas. Premature aging and other skin damage. Eye damage such as cataract problems, photokeratitis or snow blindness.
