Global warming is an issue taken up since the late eighties. Chlorofluorocarbons (or CFC’s) from industrial smoke and exhaust fumes from running vehicles on the streets seems to be the cause of the problem by depleting the ozone layer much higher up in the sky, letting in UV rays of the sun to reach us, which is dangerous for us, by warming up the global temperature so that after a specific time, a situation will arise when we will find it difficult to breathe.
This is the scenario given to us since the late eighties and covers a lot on the media. One day the natural resources on this earth will run out and we will face problems, leading us to a slow death. This is also the scenario the media wants to present to us.
