Imagine that you have been asked opinion for an environmental magazine about the success of global initiatives in solving environmental concerns, using the Montreal Protocol and ozone depletion as a focus. You can use some of the information in this lesson to help you get started, but you will have to do some additional research on the Internet. Use at least two sources, and list them in a properly formatted bibliography. In your opinion piece, clearly indicate whether you feel the Montreal Protocol has been a success or failure. Provide three detailed explanations to support your opinion. Check your spelling, grammar, and punctuation, and make sure you use scientific terms and symbols correctly
