The release of CFCs or chlorofluorocarbons into the atmosphere through human activities has caused a massive hole in the ozone layer right above Antarctica and if unchecked, melting icecaps may inundate several regions of the earth in the future.
What CFCs are and how they react with the Earth’s atmosphere.
Greenhouse gases are trapped and build up in the atmosphere near the earth’s surface. This makes the earth warmer than normal. The warning effect of the trapped greenhouse gases causes changes in the weather patterns on a global scale. Rainfall pattern changes, sea level rises and droughts prevail.
