1. If UV intensity levels doubled, mutations in animal cells, skin cancers, and cataracts would increase.
“The intensity of UV radiation reaching the Earth’s surface doubled—levels that would increase DNA mutations in human and animal cells, suppress our immune systems, and increase the incidence of cataracts and skin cancer.”

2. If the atmospheric ozone layer disappeared, plants would be unaffected.
“It was dead in a day.”

3. Chlorofluorocarbons (CFCs) are nontoxic compounds developed to be used in refrigeration systems.
“...chlorofluorocarbons (CFCs), nontoxic compounds that improved refrigeration.”

4. Most of the Earth’s ozone layer is at an altitude of about 25 miles above Earth’s surface.
“While ozone can be found through the entire atmosphere, it is mostly concentrated at an altitude of about 15 miles.”

A
5. The ozone layer filters out UV-B and UV-C light, preventing it from reaching Earth’s surface.
“... filtering two harmful forms of ultraviolet light called UV-B and UV-C.”

6. UV light causes CFCs to become more reactive.
“...CFCs break into chlorine atoms …show more content…
Cut back on chemicals that deplete it
Cut back on pollutants
Ozone was being removed from the atmosphere
Ozone-destroying chemicals were added to the atmosphere
Two-thirds of the Earth’s ozone layer disappeared by 2065 during the simulation
Chlorine is the chemical element in CFCs identified in the article as the element involved in destroying the ozone layer
Three atoms of oxygen make up a molecule of ozone
Gordon Dobson first measured the wavelengths of UV light reaching the Earth’s surface
The Montreal Protocol on Substances that Deplete the Ozone is the name of the international agreement that limits the production of CFCs
Part B
Cl + O3 ➞ ClO + O2 and ClO + O3 ➞ Cl + 2O2
The first reaction is a single replacement reaction, and the second is a decomposition
