Most people know something about the greenhouse effect. Factories send gasses such as carbon dioxide, or CO2, into the atmosphere, the air around the earth. In the past, this wasn't a problem because trees absorbed the CO2. But now people in many countries are cutting down billions of trees all around the world. At the same time, factories are sending more CO2 into the atmosphere. It's difficult to believe, but factories put billions of tons of CO2 into the atmosphere every year. One ton is over 2000 pounds, so it is a lot of pollution. There is too much CO2 and there aren't enough trees, so the world is getting warmer. In other words, we have a greenhouse effect. This is terrible for the environment.
What can we do about this? Firsts we can stop using so much coal and oil. We can learn to use different kinds of energy: the sun, wind, steam from volcanoes, and heat from inside the earth. Second, instead of cutting down trees, we should plant more trees. One tree can absorb ten pounds of carbon dioxide every year.
The trees are good for the earth's atmosphere and for Guatemala (拉丁美洲国家危地马拉).In small towns and villages in Guatemala, most women are poor and have hard lives. Trees help them in three ways. First, the Connecticut factories pay them to plant the trees. Their pay is com, not money. The com is good for their children. Second, these women know a lot about their environment. They know where to plant when to plant, and what kinds of trees to plant. For example, they plant many fruit trees. The fruit gives them vitamins for their families' diets. Other trees are good for firewood. In a few years, the women won't spend so much time looking for firewood. Third, all these trees are good for the soil. Now rain can't wash the soil down from the mountains so easily.
This plan isn't enough to stop the greenhouse effect. However, it's a start. The woman of Guatemala are helping themselves and helping their environment.
