Are you ready to take action to protect Planet Earth? You may think it impossible，but you can begin by taking some small，but important，first steps．Many children and their classes in the USA are taking action．

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 neighbourhood 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 comps 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 thrown 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 favourite products．Ask them to reduce packaging．

Children Save Water

    Another class decides to help save water．Here’s how they got started．

Miguel Salazar lives in Meridien, Texas．Every day he walks home from school and passes Carrollton Creek(小溪)．The creek is filled with rubbish．But the creek was not always this way．Miguel’s grandfather remembers flowers and plants grew along it．Many people fished there．So Miguel’s class decides to clean up the creek．They make a plan．

Class Project: Clean Up ●     Write a letter to the mayor(市长) asking her to let us have a clean-up day at Carrollton Creek．Ask her for garbage cans to keep rubbish． ●     Make posters inviting others to help． ●     Ask parents to come along and help on Clean-up Day． ●     Choose a day for the big Clean Up!

    If one person can make a difference, think how much more can get done if people work together to care for Planet Earth．
