PLN 6: Global Warming

In the video Global Warming 101 from National Geographic, saving energy and reducing the use of fossil fuels matters to the earth. This video talked about how global warming has evolved over time, and how/what we can do to slow the processes of the greenhouse effects. Global warming started during the Industrial Revolution, and that was a time of huge industrialization, and lots of CO2 and methane were being produced, which eventually made its way to the atmosphere, and got trapped. This causes heat to be trapped under the atmosphere, and the earth just basically bakes, and examples of that, would be, all of the ice around the world that’s melting, and more droughts in hotter places, like deserts, and Africa. Global warming is a problem that we can do something about. How can you do your part to help our home?
