Where do greenhouse gas emissions come from?
What happens is that places like factories emit green house gas emissions, and then they clog up the atmosphere, and not all the emissions escape into outer space. These create holes in our ozone layer. The ozone layer protects us from the harm of the sun, but with holes in the ozone layer, more of the suns rays come through, and thus heating up the planet. If you wish to know more I highly reccomend reading ‘An inconvenient truth’, By Ex- Vice- President of the United States; Al Gore, that book will explain everything.
