Which type of pollution includes CFCs and smog?

A. Air

B. Land

C. Water

D. Volcanic

Answer: A. Air

The correct answer is air pollution since it is the realistic term that incorporates CFCs (chlorofluorocarbons) and smog. Based on the given document, air pollution consists of a range of different things and substances – for example, CFC and smog. CFCs are man-made materials that are mainly employed in aerosol beings, air conditioner parts, and fridges. CFCs work towards the reduction of the ozone layer when expelled into the atmosphere and this layer is very essential in shielding the earth from risky UV. Smog, then again, is another variety of air pollution which occurs when gases such as volatile organic compounds and nitrogen oxides undergo a photochemical reaction with sunlight to produce a chemical fog in the air. Since CFCs harm the ozone layer and smog badly affects people’s health, both are dangerous for the environment and people. For example, CFCs cause the depletion of the ozone layer so the UV radiation on the earth’s surface will be increased, which will lead to skin cancer and other related diseases. These are mainly respiratory ailments, redness of the eyes and act to worsen ailments such as asthma. Thus, emissions of such pollutants affect climate change and harm ecosystems originating from these sources. It is important to be aware that CFCs and smog are part of air pollution that threatens the environment and human well-being; the knowledge of these aspects should be sufficient for the creation of proper countermeasures.
