Step-by-step explanation:

2 answer

a) The thinning is most pronounced in the polar regions, especially over Antarctica. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth's surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.

b) Seek the shade, especially between 10 AM and 4 PM.

Don't get sunburned.

Avoid tanning, and never use UV tanning beds.

Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses.

Use a broad-spectrum (UVA/UVB) sunscreen with an SPF of 15 or higher every day.
