show you more about ozone depletion and how it relates to indoor air pollution. According to our text ozone "is a naturally produced‚ essential component in the stratosphere‚ which encircles our planet some 10 to 45 km (6 to 28 mi) above the surface." (Berg‚ Hager‚ & Hassenzahl. 2011). Ozone in the stratosphere is a good thing‚ when in this layer it absorbs much of the suns ultraviolet rays and protects us from harm. In the troposphere however‚ it is a different story. Ozone there is a combination

MONTREAL PROTOCOL: The Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect theozone layer by phasing out the production of numerous substances believed to be responsible forozone depletion. The treaty was opened for signature on September 16‚ 1987‚ and entered into force on January 1‚ 1989‚ followed by a first meeting in Helsinki‚ May 1989. Since then‚ it has undergone

Environmental Science Essay Air Pollution Pollution and How It Affects Elements within an Environment Harry Bond III Everest University The Earth is entirely surrounded by a blanket of air which is called the earth’s atmosphere. The atmosphere allows human‚ plants‚ and all the earth’s creatures big and small to exist. The atmosphere protects the earth and without it the heat from the sun would burn all that is exposed to its rays

in a forest with nobody present‚ does it make a noise? Does the moon exist when there’s no-one to look at it? And is the hallway behind me still an ominous jumble of ornate casements and baleful oil paintings‚ or has it turned into something else? Layers of Fear makes space for plenty of gristle and gore during its five hour playtime‚ but the game’s greatest weapon is simply the dread of objects misbehaving when left unobserved. This is an anxiety games in general are well-placed to exploit - game

This year’s ozone hole over the South Pole is one of the worst‚ despite scientists only a year ago saying it had shrunk to its smallest size. By September 12 the hole above Antarctica was 26 million square kilometres‚ Nasa and the National Oceanic and Atmospheric Administration said. The hole – which grows each spring and then shrinks again each year – was among the 10 worst since records began 26 years ago. Colder-than-average temperatures in the stratosphere had caused the larger-than-average

Chemistry Ozone Depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as theozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polartropospheric ozone depletion events. The

A lot of people in our community cant afford the treatment to cure this type of cancer‚ and some sever cases of skin cancer could cause death. So why not prevent this from happening and wear your sunscreen? A lot of scientists now days are focused on how the chemical reaction of ultraviolet rays are causing our ozone layer to brake down. So on top of humans

This environmental issue has brought us a lot of effects like greenhouse effect‚ acid rain and ozone layer depletion. One of the effects of air pollution is greenhouse effect. Greenhouse effect means the phenomenon whereby carbon dioxide traps solar radiation in the earth’s atmosphere. As the heat is trapped in the atmosphere‚ the temperature is rising

The major sources of uncertainty include research and development‚ and market analysis. “Will the substitute product work and would it be working the same?” “Is the ozone problem really directly related to Chlorofluorocarbons‚ or a normal cycle has actually caused these observed recent changes?” Finally‚ “could Du Pont’s efforts really have an effect‚ and how much?” “Is this effect going to bring any profit for the
