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．

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．

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

Americans can travel almost anywhere they choose. But to protect (保护) its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the travelers might not be safe. These countries are listed in a small book called a passport (护照).
This passport is for the safety of its traveling people. It is also a government’s pledge (保证) that the people will follow the rules of the host country. To receive a passport from the government, a traveler must show that he is an American citizen (公民). An American cannot go abroad without a passport. Only the close countries such as Canada and Mexico do not ask for passports. The traveler’s picture is inside the passport. Children traveling with their parents are also in one parent’s book.
Thousands of people from the United States visit other countries every year. An American traveler might carry plane tickets, money, clothing and many other things. But the most important thing that he carries in another country is his passport.
