Kangaroos have long been a nuisance to many Australian farmers.Keeping these kinds of animals away from their crops and water supplies has become a continuous fight.A traditional way has been a series of the huge screaming(尖叫) from loudspeakers.Researchers found that kangaroos often become used to these manmade sounds and take little notice of them.
Australian farmers could be about to get an unusual new weapon(武器) to protect their crops from kangaroos.Researchers in Melbourne found that kangaroos can be frightened away by the loud sound of their own large feet.It appears to be quite a breakthrough.This is the noise these animals make when they feel danger before running away quickly.Using the animals' own alarm system could be what angry farmers have been looking for.
Animal rights protectors are happy about this new finding.When people complain that the number of kangaroos has risen quickly，they say that a large number of kangaroos have been killed or injured on Australian roads by cars and trucks.Also，they don't want several million to be shot dead every year by human beings.Researchers，who are hoping to develop their footstep sound technology，believe it could also be used to lead kangaroos away from busy highways.The protectors are in favor of this solution which can prevent kangaroos from being harmed and also please the farmers.
