Chlorofluorocarbons (CFCs) revolutionized personal and industrial life for many years. They were the coolants in refrigerators and propellants in aerosols, pressure packs and fire extinguishers until the EPA developed regulatory programs restricting their use.
Which of the following arguments BEST describes why the EPA began to restrict the use of this substance as part of a solution to reduce the impact on the environment?
A
Chlorofluorocarbons have a negative impact on the environment because they cause ozone depletion
B
Chlorofluorocarbons have a negative impact on the environment because they add carbon to the atmosphere
С
Chlorofluorocarbons have a negative impact on the environment because they cause air pollution
D
Chlorofluorocarbons have a negative impact on the environment because they cause cancer

Answer questions from exploring further

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
