What negative impact did chemistry have on society through the production and use of chlorofluorocarbons (cfcs)?

The CFCs leads to lower levels of ozone in the stratosphere, which had permitted more ultraviolet radiation to reach the surface of the Earth.

Explanation:

The CFCs or chlorofluorocarbons refers to an array of compounds that comprise the elements fluorine, chlorine, and carbon. The CFCs does not have any direct influence on the environment in the instantaneous vicinity of their discharge. However, on a global scale, the discharging of CFCs exhibits some serious environmental outcomes.  

Their presence in the atmosphere signifies that some reach to the stratosphere and destroy the layer of ozone, thus minimizing the safeguarding it provides the Earth from the harmful UV rays of the Sun. It also contributes to Global Warming.
