The Ozone Layer

On Tuesday, the European Space Agency (ESA) reported that the hole in the Ozone Layer above Antarctica, which protects the life on Earth from UV rays, has grown to 27 million square kilometers. This has occurred partly because of extreme cold at high altitudes and also some man-made gases, such as chlorine. I think this report is definitely bad news, especially since this hole has grown bigger since last year. Although chlorofluorocarbons (CFCs), which produced gases that harmed the ozone layer, have already been banned from use, the ozone layer is still shrinking. I think that we should do more to protect it. Or else, not only might the ultraviolet rays cause the marine animals harm, but possibly give us skin cancer and cataracts as well.
