Cars that have pollution are not good for the earth because it makes the earth sick, and litter too! People could make cars without pollution and try to make less garbage. Walk to school instead of drive, or go on a bike. Anything that doesn't make pollution is good.
Kids who don't have toys you should give your toys to them so it's no money for them. Share your toys even with kids you don't know. Then you're being a good friend. I call it bucket filling.
