We’ve all heard the saying “Go Green”, but is it important? Can one person really make any difference? These may all be questions you’re asking yourself. Our main source of energy, at the moment, is fossil fuels. We’ve been using fossil fuels for decades now, so why stop? You see, fossil fuels are created over time by the earth, and can only be replaced over time by the earth, but we were using them faster than the earth could produce them. On top of stripping(剥夺)the earth of her natural resources, we’re also damaging the atmosphere by burning things like coal, oil, and natural gases. That’s the greenhouse effect, which occurs when the burning of these fossil fuels help trap the sun’s energy inside the earth’s atmosphere, causing the temperature to rise over time. With all the people in the world, how could you possibly make a difference? Well, here are a few things to think about. How many lights do you use in your house? How many miles do you drive to work? How many electronics do you use, which you don’t need? If you were to stop and think about it, you’re able to make a bigger difference than you might realize. So many times you’ll hear people say, “So what? I won’t be around for it when things go bad.” But bad times are coming quicker than you might like to believe. It’ll be you children, or maybe even your grandchildren. With the temperature ever-rising, the polar ice caps are melting and water begins taking over land, so many people will crowd into so little space. As you can see, this is no laughing matter. It’s time to take action. Don’t let your children or grandchildren live in a world without hope. One person at a time, we can begin to save this earth. 60. The passage is mainly to _______.
