We should not drive our cars so much. Driving pollutes the air. Instead you could ride your bike. Air pollution causes Global Warming. As we pollute our atmosphere, we trap heat from the sun. This is making our Earth get warmer and warmer. It is causing polar bears to die because the ice where they live is melting and they cannot swim that long. We also shouldn't smoke. Factories also pollute the air. Smoke stacks add pollution to the air. We should plant more trees! They suck in the bad air and make oxygen! We also need to cut down less trees. We will talk to you soon.
