Answer:
C. include global warming, which is greatly enhanced by society's production of greenhouse gas
Explanation:
Human activities such as burning of fossil fuel, industrial waste has lead to the emission of greenhouses such as carbondioxide, carbon monoxide, methane, chlorofloro carbon accumulation of which in the atmosphere leads to global warming as a result of the depletion of the ozone layer and the direct impact of sun on the earth.
The depleted ozone layer has lead to the constant and high temperature
that is affecting the earth.
