Answer 2

Stratospheric ozone, otherwise known as the ozone layer, is a layer of gas (O3) that partially shields the earth from the sun’s ultraviolet (UV) radiation. In the latter-half of the 20th century, use of chlorofluorocarbons (CFCs) punched a hole in the ozone layer up to 11.4 million square miles in size and thinned it elsewhere. The increased UV rays have lead to higher rates of skin cancer and eye problems. The good news is that bans on CFCs have significantly slowed the growth of the ozone hole.[1] By avoiding products and practices that damage the ozone layer and by lobbying for more action from government and industries, you can help to close the hole by the end of this century.
