Earth's energy is limited. Rivers are usually dirty, smelly and full of garbage, so we won't have enough to drink in the future. Trees are used to made timbers to be built into houses and furniture. When the trees have disappeared and CO2 will make the temperuture high. Then the rice in the north and south will melt quickly. The ocean will rise higher and higher, so many low-lying places will be flooded and some animals won't be able to live in this kind of environment. Looking at this problem, the Earth's environment will have a lot ofchange if we keep using the energy and don't conserve. When the environmenaven't find any prout changes, super earthquakes or hurricanes could happen. Without these gussing, earth could be hit by huge rocks, but the scientists haven't find any proof yet. Although we can't stop it, I think we should do our best to slow it down.
