    Policy Implications from the Montreal Protocol Executive Summary In the mid 1980s, the international community decided to address the issue of ozone depletion. In 1987, the Montreal Protocol was signed, setting out abatement schedules for major ozone depleting substances. Due to several unique factors surrounding the issue of ozone depletion, the Montreal Protocol was, and continues to be, a great success. That being said, there are a number of problems that parties to the agreement have

    content they are even more destructive to ozone than CFCs, and an amendment to the Montreal Protocol banned their use by 1994. Hydrochlorofluorocarbons (HCFCs) are organic compounds that are similar to CFCs but less destructive to ozone. HCFCs consist of carbon, hydrogen, chlorine and fluorine. They are used as replacements for CFCs, but are to be phased out by the year 2020, as specified by the Montreal Protocol as amended, when they are expected to be replaced by hydrofluorocarbons (HFCs)

    to simulate what other variants affect the ozone layer, not just the ones we know are harmful. As new products and chemicals are discovered or made, they need to be tested to gauge what, if any impact they will have on the ozone layer. The Montreal Protocol needs to be an ever evolving agreement. I would suggest an annual meeting with all its participants to re-address the list of banned substances and add new ones as they are discovered. With this knowledge we will be able to ensure that are species

    pollution can lead to the deteriorating of the ozone layer, the ozone layer is a layer of ozone (O3 gas) in the atmosphere that reflects most of the Sun’s UV-B radiation (radiation that is harmful to humans and all living things). Additionally, the Montreal Protocol, is an international agreement to protect the ozone layer from deteriorating chemicals, it has been signed by 197 countries to protect the ozone layer. There are also many Canadian initiatives that are in effect to protect the ozone layer. These

    Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The

    Global Warming and Chlorofluorocarbons (CFCs) Chlorofluorocarbons are non-toxic, non-flammable chemicals that are mainly used in the manufacturing of aerosols, blowing agents for foams and packing materials, as solvents, and as refrigerants. They are classified as Halocarbons, a class of compounds that contain carbon and halogen atoms, and are amongst a group of substances called “greenhouse gases”. They eat away at our ozone and raise the temperature of our planet significantly, causing detrimental

    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 made

Well read the following and decide. If you're not motivated to do so, consider that if ozone weren't part of the Earth, neither would we be, and, more immediately, if ozone levels aren't kept within certain narrow ranges in the future, the biosphere will suffer greatly. What is ozone? Ozone is the gas in
