Thc Greenhouse Effcct and the
Women of Guatemala

Most people know something about the greenhouse effect. Factories send gases 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, or drank in, CO2. But now people are cutting down billions of trees in many countries. At the same time, factories are sending more CO2 into the atmosphere. lt’s difficult to believe, but factories put billions of tons of CO2 ¡nto the atmosphere evry year! One ton is 2,000 pounds, so this 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? First, we can stop using so much coal and oil. We can learn to use different kinds of energy: the sun, wind, and heat from volcanoes and 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.

ln the past, the mountains of Guatemala, in Central America, were green and thick with beautiful trees. But people cut down trees for houses. Also, many women cook over wood fires. They walk hours every day to look for firewood. There are fewer and fewer trees, and this is bad for the land. Rain washes good soil down the mountains.
Far away from Guatemala, in the state of Connecticut, there is a new factory. The factory uses coal. It will send 400,000 tons of CO2 into the atmosphere every year. Many people are angry about this. But the factory owners are doing something about it. They are giving two million dollars to the women of Guatemala. The Guatemalans will plant trees in their country. These trees in Central America wiII absorb the carbon dioxide from the factory in Connecticut.
Why Guatemala? Why don’t people in Connecticut plant the trees in Connecticut? The answer is easy. Trees grow much faster in Central
America than in the northern part of the United States.
The trees are good for the earth’s atmosphere. They’re good for Guatemala too. In small towns and villages in Guatemala, most women are poor and have hard lives. Trees help them in three ways. First, the Connecticut factory pays them to plant the trees. Their pay is corn, not money. The corn is food 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 ttiem vitamins in their families’ diets. Other trees are good for firewood. In a few years, the women won’t spend so much time walking for wood. Third, all these trees are good for the soil. Now rain can’t wash the soil down the mountains so easily.
This plan isn’t enough to stop the grenhouse effect. But it’s a beginning. The women of Guatemala are helping themselves and helping their environment. As one woman says, “We’re planting for our famihies, for our children.”

My Change of Mind
When I finished high school back home in Brazil, I took computer
programming classes. I thought, “I can get a good job.” But I wasn’t realiy happy. I wanted to do something very different. I was eighteen years old, but I still needed to grow up. So I came to the United States, to California. My idea was to go to college. I wanted to study computer science. I didn’t speak much English, so I had to go to an adult school to Iearn the language. l’m finishing my second year now. In these two years, my whole life changed.
In California, I wanted to practice listening in English, so I watched a lot of TV programs. I especially liked programs about the environment. My listening got better, but I began to worry about the land, air, water, and animals. I saw dead animals in oil in Alaska. I saw air pollution in many cities. And I learned a lot about my own country. In Brazil, people are cutting down the ram forests. Most of my friends don’t think about the enviroriment. Back home, I never thought about it either.
I began to read more about the environment. I wrote letters to environmental organizations such as Greenpeace and the Sierra Club. They sent me lots of information! Then, on National Beach Cleanup Day, I volunteered to help. They made me the leader of a team of volunteers on Santa Monica Beach. It was hot, dirty, difficult work, but it was exciting. I met some nice people, and that night I was on the TV news!
Next September I’lI start college. I have to do this in English. It won’t be easy, but now English is so much a part of me! I’m making a big change. I’m going to study environmental science. My special area wiII be marine mammals—dolphins, whales, and sea Iions.
When I came to this country, I felt lonely. I cried a lot. Now l’m happy and excited. There I am in the photo next to the seals. l’m going to Start my new life!
