Chlorofluorocarbon

"CFC's: These substances are also of concern in connection with the destruction of stratospheric ozone" [Bunce, N. Environmental Chemistry (Winnipeg: Wuerz, 1994, p. 19)] b. For longer quotes it is appropriate to indent the entire passage: Chlorofluorocarbons, CFCs: These substances are also of concern in connection with the destruction of stratospheric ozone (Chapter 2). Like N2O, they have no tropospheric sinks, but are infrared absorbers. Up to 1984, the tropospheric concentrations of three of

New Character- “Grandpa Joe” My character, “Grandpa Joe,” is 98 years old, and he loves to share stories about what life used to be like in the “good old days.” Humanist Approach Mother: “Memorization of poetry is really important; you never, when it will come up again.” Grandpa Joe: “You know, kids, your mom is right. You never know when you might need to use any of this valuable knowledge you are learning in school. Make sure you pay lots of attention and absorb as much as you can. Now, that

planet that does not support living things. Today, this manifests in climate change. It is easy for many to confuse these two issues, although they are connected in various ways. Loss of the ozone layer is caused by greenhouse gases such as chlorofluorocarbons or CFCs (compounds with chlorine and/or fluorine attached to carbon), as well as , halons (similar compounds with bromine or iodine) (Jain 2015). These chemicals can stay in the atmosphere for up to 100 years causing damage(What is Ozone Layer

Ozone Depletion and Industrial Output For years, we have heard about the ozone crisis: that because of industrialization and the lack of pollution-consciousness by our industries, governments, and academia, we have put so many environmentally harmful products into the atmosphere that our ozone – the good kind, the kind that protects us from harmful UV radiation – is becoming dangerously damaged. It is becoming thinner and developing holes, like the large hole over Antarctica. Predictions

in employment areas away from the middlemen to the two working ends of the process, resulting in increased productivity and efficiency in many fields in society. Chemical Knowledge: Chlorofluorocarbons Growth of the hole in the Ozone Layer Growth of the hole in the Ozone Layer In the 1930s chlorofluorocarbons (CFCs) became an industrial staple due to their

The Ozone Threat: Managing with Uncertainty The ozone layer serves as protection of the Earth from the sun’s harmful ultraviolet rays. Over a span of decades it has been found out and continuously theorized that the said layer is thinning or depleting. This depletion is speculated by scientific experts to have negative effects to human beings and most importantly to the environment. Studies have been done regarding the possible negative effects of the depletion of the ozone layer. First, it

Montreal Protocol is a classic case of a domestic debate being internationalised at the world stage. The initial controversy started in the United States in the 1970s with the advent of scientific research on the link between a chemical called Chlorofluorocarbon (also known as CFC) popularly used in the aerosols, air conditioning and refrigeration, solvents, foams and fire retardants sectors, and ozone depletion. This scientific discovery generated health concerns among the population as the thinning

Global warming Global warming is a gradual process of heating of earth’s surface and whole environment including oceans, ice caps, etc. The global rise in atmospheric temperature has been clearly noticed in the recent years. According to the Environmental Protection Agency, in the past century there is increase in the earth’s surface average temperature by around 1.4-degree Fahrenheit. It has also been estimated that global temperature may increase by another 2 to 11.5 degrees F in the next century

Environment - how can you help protect it? Our planet is in trouble! Almost every day we seem to hear of yet another problem affecting the environment - and what a list of problems! - pollution, acid rain, climate change, the destruction of rainforests and other wild habitats, the decline and extinction of thousands of species of animals and plants....and so on. Nowadays, most of us know that these threats exist and that humans have caused them. Many of us are very worried about the future of our
