How can Omar’s class help?
Omar’s class at school learned about taking care of our planet. Children in his class worked hard at collecting newspapers, cans, and bottles. Their teacher took what they collected to a company where the things would be recycled（回收）and used again. Omar hoped that doing his would make progress toward cleaning up our Earth. Omar wished that they could do more. Then Omar’s teacher gave the class this form.
