What is at the top of the world’s food chain? People are! 3 We could not run faster than cheetahs (猎豹), but we invented cars. Now we can move the fastest. We could not fight better than lions, but we invented guns. Now we can hunt the best.
People’s inventions are clever, but they can be dangerous too. For example, people invented plastics, and now they make the air and rivers dirty. 4 Dirty rivers kill fish. The bears have no fish to eat and they die. If we kill one part of the food chain, other parts may also die.
