The perfect world ! Well, not really perfect, only without pollution. Imagine what the world would be like if we never polluted, I'm talking about from the beginning of time, never! Well, if we never burned our garbage, the ozone wouldn't be destroyed and the sun wouldn't be so harmful to our skin. The bad thing is there would be no automobiles because they pollute, nor trains, planes, or even rocket ships. maybe they would have thought of a clean way to create engines.

Just beautiful green grass and healthy trees. Clear lakes and oceans, happy little fish, and clean beaches and riverbeds, due to no toxic waste dumping or garbage hiding.

 
There might have been solar cars! Think of a highway full of speedy little, humming, clean solar cars! Wouldn't it be great to go to the park and not see a single piece of garbage?
