Reuse We should decrease the amount of finite materials that we use.

Recycle We should decide whether we need products before we buy them.

Refuse We should think of another use for a product before we throw it away.

Repair We should decide not to buy products that harm the environment.

Rethink We should make sure that products are converted back to their basic materials and then remade into new products.
