Once plentiful around the world, the number of peregrine falcons (游隼) began to fall after World War II with the introduction of pesticides like dieldrin, aldrin and DDT. Dieldrin and aldrin killed the birds directly, while DDT weakened chicks eggshells, lowering their chances of survival. In the US, the falcons’ number reached a low point of 324 pairs in 1974 - a sharp decline from more than 3,800 pairs before the mid-20th century.
Peregrine falcons were placed on the endangered species list in 1970. The US Environmental Protection Agency banned (禁止) the use of DDT in 1972. Two years later, the agency banned most use of aldrin and dieldrin, with an exception for white ant control.
Before long, the bans worked. Four climbers made a surprising discovery while climbing Yosemite’s EI Capitan in 1978: an active peregrine falcon nest, which had not been seen in the area for decades. They reported their find to the Santa Cruz Predatory Bird Research Group, who quickly took action. They came up with an ambitious plan and asked the climbers if they wanted to help. At their request, the climbers once again climbed EI Capitan, but this time, they collected samples of eggs from the nest and brought them back down for testing. The eggs were delicate and thin, so researchers decided to incubate (孵化) them in a lab, and then rock climbers risked their lives returning the chicks to the nest.
Peregrine falcons were removed from the endangered species list in 1999. As many as 40,000 individuals may now be flying freely in North America. Without the cooperation of climbers, peregrine falcons might still be struggling to gain a foothold in Yosemite. Instead, the birds’ recovery is a rare success story where humans prioritized the needs of other species above their own.
28．What caused the drop in the number of peregrine falcons
A．World War II. B．The chemicals. C．City development. D．Air pollution.
29．How did the climbers help the Bird Research Group
