In 1990, Congress amended the Clean Air Act with Title VI, with provisions for protecting the ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.
Effects of stratospheric ozone depletion, and the subsequent increased UV-B radiation, on the useful lifetimes of plastics will be more severe in locations that experience high ambient temperatures. Understanding the role of temperature, together with UV-B irradiation, is scientifically and economically important.
Ozone Layer was agreed in 1985, by governments determined to protect human health and the environment against adverse effects resulting from the depletion of the Earth's protective ozone layer. The Parties that agreed the Convention were aware that measures to protect the ozone layer from modifications due to human activities required
Other kinds of eye damage include pterygium (i.e., tissue growth that can block vision), skin cancer around the eyes, and degeneration of the macula (i.e., the part of the retina where visual perception is most acute).All of these problems can be lessened with proper eye protection from UV radiation. Immune Suppression. Scientists have found that overexposure to UV radiation …

Health and Environmental Effects of Ozone Layer Depletion. There are three types of UV light: UVA, UVB, and UVC. Reductions in stratospheric ozone levels will lead to higher levels of UVB reaching the Earth's surface. The sun's output of UVB does not change; rather, less ozone means less protection, and hence more UVB reaches the Earth.
