Children Campaign Against Waste
Children are paying attention to the packaging (包装) of the things they buy. Packaging includes all the things
you throw away when you unwrap anything new. One third of all rubbish is packaging. Mrs. Perez"s 4th grade
class decides to make their school and neighborhood know the waste in packaging. They want people to think
before they buy. They also want to let people who make the products know that they want less waste in
packaging. So they start a campaign to help people change how they shop.
| Class Project: Campaign Against Waste ·Find out the facts. Use the websites to find out how much waste comes from packaging. ·Go on a trip to the shops. Take notes about how products, such as CDs, are packaged. Report on how much will be throw away. ·Say no to bags. If we don"t need one, we don"t use one. ·Make posters to tell others what they can do. ·Talk to our families and friends about what we learn. ·Write class letters to the people who produce our favorite products. Ask them to reduce packaging. | ||||||||||||||||||||||||||||||||||||||||

| Plants and animals, including humans, need food and water to live on. These are from the natural resources (资源) on Earth. To protect these resources, we need to keep the air clean and the water drinkable. We need to keep the soil healthy. How do we do that? * Protect the land The soil that covers fields and farms provides much of the food we eat. Human activities such as plowing (耕) fields, mining (采矿), and building highways can destroy (破坏) the land. Erosion happen when wind and water carry away the soil. Soil erosion can turn rich farmland into a desert wasteland. So does this mean we shouldn"t build a highway or plow a field? Of course not. But it does mean we might think about Earth-friendly ways of doing those things. Today farmers plow their fields in different ways to prevent erosion. They try to use less water for their crops. They keep animals from eating the growing grass in just one area. Farmers also plant trees to prevent erosion from happening. * Save the Trees Another human activity that damages the land is deforestation (采伐森林). People take away a large number of trees from a forest. Millions of square kilometers of forest disappear each year. When this happens, many plants and animals lose their places to live. They may die out, or become very few. Scientists haven"t even discovered all the living things in the forest. We may be losing some without even knowing they are there. Trees absorb (吸收) and use carbon dioxide (二氧化碳) when they make food. Environmentalists encourage careful management of the forests. They ask people to replant trees after they cut down the forest. * Recycle, Reuse, Reduce People throw a piece of paper into the wastebasket after using it. The paper becomes trash. Where does the trash go next? Much of our trash ends up in landfills (垃圾填埋地). They take up valuable land and sometimes pollute the water, air, and land around them. More than a third of the trash in landfills is paper. Recycling, reusing, and reducing what you throw away can cut down on the need for more landfills. In fact, we can recycle about eighty percent of household trash. | ||||||||||||||||||||||||||||||||||||||||

| Have you ever planted a few trees on Tree Planting Day? Each year, millions of people, both 1 , plant a lot of trees. But this may not be the best way to make your home a 2 place. Last week we visited a park in Hebei. We were 3 to find most of the trees had been burned. The workers told us that the trees 4 soon after they were planted because they weren"t watered well enough. 5 workers burned them and cleaned the place for 6 trees to be planted this year. 7 a card found in one of the dead trees, a student wrote:"I hope this tree will grow up with me to 8 the backbone (栋梁) of our country." The workers said that the survival (存活) of the trees was really more important than 9 trees were planted. Some people in Beijing now have a new idea that they can donate (损赠) some money and let professionals (专业人士) plant and 10 the trees. | ||||||||||||||||||||||||||||||||||||||||
