If penguins could fly then they could get away from predators faster but then there would be an over population of penguins and at the zoo you would have to keep them in a cage and clean it. Also if penguins could fly the world could get over taken by penguins and we wouldn't be able to drive without seeing a sign that says: "beware of the penguins!" how would you feel if you saw that sign? I know that I would be terrified.
