A Drop in the Ocean

Trócaire have made a documentary about climate change and how it will affect Ireland called "A Drop in the Ocean"
The name, drop in the Ocean is a great way to explain global warming. One person only puts one drop of carbon dioxide into the atmosphere a year. In proportion to the amount of carbon dioxide in the atmosphere it's only a little, but with all 5 billion people creating one drop, we end up with a large ocean, increasing each year. If everyone decreased their carbon emissions it's another ocean of carbon dioxide stopped from entering the atmosphere
