According to the Environmental Protection Agency, ozone depletion is mostly due to the corrosive actions of certain chemical compounds, such as refrigerants. Halting ozone depletion hinges on banning the use of these substances or preventing their release into the atmosphere. Because many of these compounds are extremely long-lived, molecules that escape into the atmosphere can cause ozone damage for decades.Continue Reading
Ozone molecules consist of three oxygen molecules, and are an important protective part of Earth's atmosphere. Certain catalysts, such as hydroxyls, nitric oxide, chlorine and bromine atoms, have the ability to break the bonds of ozone molecules, effectively destroying them by converting the oxygen into other compounds. Compounds called chlorofluorocarbons, or CFCs, contain many of these catalysts, and are particularly dangerous to the ozone layer. The Montreal Protocol banned their use in 1989, although they are not the only source of potentially ozone-destroying compounds.
As of 2014, any chemical that contains catalysts that could be dangerous to ozone is heavily regulated. Many of these substances are vital for manufacturing and chemical engineering, and are used in tightly-controlled conditions to prevent their escape into the atmosphere. The reduction in ozone-depleting chemicals is expected to allow the ozone layer to recover to pre-1980 levels by the year 2075.Learn more about Environmental Science
According to the Foundation for Sustainable Development, India's high population, coupled with its comparatively small geographic size, has resulted in major environmental degradation, including the loss of forests and the depletion of water and other natural resources. Air pollution, water pollution and an abundance of solid waste are major problems on the Indian subcontinent.Full Answer >
Effects of environmental destruction include global warming, climate change, ozone layer depletion, land degradation and human disease. Environmental destruction occurs when events deplete the earth's natural resources. Its main causes are technological, institutional and socio-economic activities.Full Answer >
The Environmental Protection Agency explains that the ozone layer of the atmosphere, Earth's protective layer, is being damaged by human activities, particularly the production of greenhouse gases. These gases are known to erode the surface of the ozone layer, meaning that its protective properties are consistently being diminished over time.Full Answer >
Without the ozone layer, the sun's ultraviolet radiation would negatively affect life on land and in the water, leading to mass extinction. The ozone layer is a protective area of the Earth's stratosphere that absorbs between 97 and 99 percent of the sun's UV radiation, allowing life to exist.Full Answer >
