ent Spring I. Text Analysis Question: Why did Carson say the For chemical war is never won? Reference Chemicals kill indiscriminately, reduce biodiversity and contaminate the entire environment. They cannot solve the pest problem, for pests can adapt to the chemicals and evolve into super races immune to chemicals, and they can undergo a"flare-back" The vicious circle will never end until man is killed along with other lives W BTL E To be continued on the next page

ent Spring I. Text Analysis Question: What is the difference between the natural spreading of species and the man-assisted process? And how does this process contribute to the pest problem? The natural spreading of the species involves the restraining hand of natura enemies that keep down its numbers in its native land An alien species is introduced by man into a new territory finds no natural enemies, thus becoming enormously abundant in number.
