However, Uncle Sid says that some things will get worse in the next century．If more people use cars, there will be more pollution．Also, if there are fewer trees, the air will become dirtier．If pollution gets really bad, maybe people will have to go and live on Mars．Uncle Sid says we’ll be very sorry if pollution becomes worse．
