Preet Chahl - Block 4 =__**What changes can society make in order to deal with the problems associated with climate change?**__= = = =The main cause of climate change is human activity. Humans need automobiles, automobiles need fossil fuels, and fossil fuels burn in cars and go into the atmosphere. The atmosphere was naturally made so the right amount of the sun’s radiation can be absorbed or reflected. As you can see in the pie chart below, over half of the pollution in the atmosphere is from carbon dioxide. Also the graph on the right shows the concentration of carbon dioxide gases in the atmosphere over many decades.= = = =Society needs to become less reliant on fossil fuels because eventually either the fossil fuels will run out, or everyone will die on the Earth because of excessive heat from the Sun’s trapped radiation. Your carbon footprint is the amount of impact you have on the environment. The smaller your footprint, the less impact you have. Another way to reduce our carbon footprint, is to change the way we consume energy. A good place to start is to change your old light bulbs to compact fluorescent light bulbs. It is a good start, but if you really want to help the environment, you can install solar panels on your house. There are many problems associated with climate change, such as high temperatures, and there are little things we can do like changing our light bulbs which can have a big impact.=
