Think about a world without insects. It might sound nice at first. There would be no flies in your room. 16
The number of insects is becoming less and less, according to the British biologist Dave Goulson. “In the 27 years from 1989 to 2016, the number of insects fell by 75 percent,” Goulson wrote. 17 They are bad for the places that insects live in.
What would happen without insects? 18 But the results would be far-reaching（深远的）. We need insects to pollinate crops（庄稼）. They also break down dead plants and animals and turn them into new useful things. We need them to keep the soil（土壤）healthy and do much more. 19 They would go hungry and die. The ecosystem would be off balance.
“The first step to stop this is to let more people understand the value（价值）of the natural world,” Goulson said. “ 20 We should encourage them to protect the environment（环境）from an early age.”
A. It's really difficult to give an answer.
B. But in fact, this could be really bad news.
C. The best place to start is with our children.
D. Without insects, many animals would have nothing to eat.
E. Everyone should play a part in protecting the environment.
F. Scientists say the main reason for this is the use of pesticides（农药）.
