Based on your observation, what can you conclude from the graph?
The 1987 Clean Air Act led to a dramatic reduction in total global greenhouse
emissions.
Use of CFCS contributed to an increase in emissions of ozone-depleting chemicals
from both anthropogenic and natural sources.
Forbidding the production of ozone-depleting chemicals, such as CFCS, worked
quickly to completely eliminate their use.
Actions taken to comply with the Montreal Protocol greatly reduced the use of CFCS
and other ozone-depleting substances.
