Ozone depletion is a global problem: ozone layer is a system of earth. And in 1985, the ozone hole was discovered over Antarctica.
2. In 2000, the international community banned dangerous chemicals known as chlorofluorocarbons (CFCs) that contribute to their deterioration.
3. Atmospheric scientific community:
Environmental social movement (in the US): the US environmental movement had been growing in strength and organisation and solidified the global ozone movement
Companies using CFCs: the ozone layer is slowly recovering
The United States: the United States helped DuPont to developed alternative chemicals. At the same time, the US initiated the ban and led the rest of European countries 
4. is successful. In 1986, DuPont had successfully developed alternative chemicals that were not harmful to the ozone layer, and at this point it was in their interest to support an international ban on CFCS.

Because this is a global problem, a serious environmental problem and its harm are facing to all of humanity.
2. to ban the dangerous chemicals that were responsible for its deterioration – chlorofluorocarbons (CFCs). US-based NGOs shared their inventive campaigning approaches and tactics, which saw similar campaigns – putting pressure on both governments and local businesses – being launched by civil society in countries around the world. 
3 company: Dupont： It began to work on alternatives
Environmental social movement (in the US)： Friends of the Earth-USA launched a “Styro-Wars” campaign
America supported Dupont accepting the ban on CFCs.
4. It is successful. DuPont successfully find alternative chemicals that did not hurt the ozone in 1986.]]> 2022-03-03 13:29:49 UTC https://padlet.com/usictech/xd2ipq5ccy5h5mco/wish/2075786884 group 3 hstang2 https://padlet.com/usictech/xd2ipq5ccy5h5mco/wish/2075787447  What is ozone depletion and why is it a global problem?
 vastly increasing the incidence of skin cancer, cataracts and other harms to humans and wildlife on earth. 
 What was the global solution reached to address this problem?ban the dangerous chemicals that were responsible for its deterioration – chlorofluorocarbons, cut the use of CFCs in half
Based on the information in the article, write a brief description of what was the contribution of each of the following actors involved in the implementation of the global agreement to reduce ozone layer depletion.
Atmospheric scientific community: the reduction of using CFCs in Mc Donald.
Environmental social movement (in the US):the US environmental movement had been growing in strength and organisation. The ozone layer campaign became the first major unifying campaign of organisations like Friends of the Earth and Sierra Club
Companies using CFCs: 80% were consumed 
The United States:the US took the lead in pushing for a ban.
According to the article, has this solution been successful? Why? Yes as DuPont had successfully developed alternative chemicals that did not harm the ozone layer, at which point it became in their interest to support international ban on CFCs.

It is a global problem because of the effects on humans and all life on earth if the ozone layer is destroyed.
2, An international treaty was introduced to halve the use of chlorofluorocarbons. 
     The use of CFCs was completely banned in industrialised countries in 2000 and in developing countries in 2010
3, Scientists have published some important theories
    The environmental social movement organised awareness campaigns to reach a wider audience. and encouraged people to address everyday products that contain CFCs.
    McDonald's has committed to reducing the amount of CFCs from its packaging.
    The US supports the ban.
4, succeeded because on the one hand it was really harmful to the earth's environment and to living things, and on the other hand alternatives to CFCs were developed, and these alternatives were not harmful to the ozone layer.
