, очень C _ _ _ _ _ d _ _ _ _ _ _ is a gas produced by traffic, industry and domestic heating and is one of the g _ _ _ _ _ _ _ _ _ g _ _ _ _ that are heating up the planet. We don’t know how much g _ _ _ _ _ w _ _ _ _ _ _ there will be this century but some scientists think the temperature will rise by five degrees.

Everyone can reduce their c _ _ _ _ _ f _ _ _ _ _ _ _ _ . For example, by driving h _ _ _ _ _ c _ _ _, r _ _ _ _ _ _ _ _ paper and glass and buying e _ _ _ _ _ s _ _ _ _ _ light bulbs. These are all e _ _ -f _ _ _ _ _ _ _ ways to help save our planet.
