Reduce. Reduce the amount of new stuff you buy. To reduce waste, buy things that have less packaging.
Reuse. Try to borrow or rent things you'll only need for a short amount of time, and reuse the things you already have. When you have things you no longer need, give them to others who can use them. Use reusable bags when you go shopping.
Recycle. Remember to recycle whatever materials you can, like bottles, cans, and paper, so they can be collected and remade into new products.
Buy recycled. Choose products made from recycled materials whenever you can.
Teach your school the three R's. Schools can save energy, preserve natural resources, and prevent greenhouse gas emissions by reducing, reusing, and recycling.
