Recently, the release of chlorofluorocarbons, or CFCs, has caused an increase in the depletion of the ozone which in turn causes an excessive amount of ultraviolet, or UV, radiation to reach the earth. According to “Health and Environmental,” “A 10% reduction in ozone could lead to as much as a 15-20% increase in UV exposure depending on the biological process being considered.” This creates a lot of problems because an increase in UV radiation creates biological effects, or health effects, in a lot of organisms. The biological effects of excessive UV radiation due to ozone depletion effects the health of humans, plants, and animals. There are many human health problems due to an increased amount of UV radiation reaching the earth. For example, higher levels of UV radiation can cause eye diseases like cataracts since our eyes are usually left exposed to the sun. Sunglasses can protect our eyes to a certain extent, but with excessive radiation, sunglasses will no longer be able to protect our eyes (“Some Effects”). In fact, it has been shown in the United States that people who live in areas with more sun, like in the south, are two times more likely to develop cataracts than those who live in less sunny places, like in the north. Furthermore, “the prevalence of cataract after age 30 approximately doubling each decade” is due to an increase in more harmful forms of UV radiation reaching earth’s surface (“Health Effects”). Another biological effect is that an excessive…
