科技高度发达的21世纪,环境问题越来越引起人们的关注,保持大自然的生态平衡已成为大多数人的共识。也许我们读过梅涛的《生物入侵者》,不妨再读读周保春的《有乡土植物才有鸟语虫鸣》,这对了解乡土动植物对大都市的意义是有启迪的。 In the 21st century with highly developed science and technology, environmental issues have drawn increasing attention and maintaining the ecological balance of nature has become the consensus of most people. Maybe we have read Mei Tao's “biological invaders” and may wish to read Zhou Baochun's “native plants have birds and insects”, which is enlightening to understand the significance of native flora and fauna to the metropolis.
