  and they release oxygen back into the air! If
  trees didnt do this, we would run out of air!

  furniture, boats, and toys!

  scientists are working on ways to make coal
  cleaner.

• We use natural gas to heat our homes and we cook
  with it!
• Natural Gas does not smell at all and we cant
  see it! In order to make it safe for our houses,
  an odor is added to it before it is pumped to us
  so we can smell the gas if there is a leak.
