Answer 2

ozone layer protects us from UV-B and UV-C

in 1985, scientist found a hole-thought ozone layer would be gone by 2050, it was over Antarctica

Scientists used chlorofluorocarbons to see how the whole formed.

CFC’s were harmful due to long life span and made carbon monoxide, and other molecules bumped into them to release them to destroy other molecules

Dobson units are used for ozone depletion

Montreal protocol said:

• emit none of CFC

-reduce ozone depleting substances and give aid to developing countries for use of alternative technology/products.
