▲閱讀下文，回答第 46−50 題In 2018, the Formosan rock monkey was removed from the “ rare and valuable ” speciesgroup to the “ ordinary wildlife ” species group on the list of protected wildlife. Also known asTaiwan mi hou (臺灣獼猴), this native species unique to the island is now a common cause forcomplaint.The Formosan rock monkey was endangered by overhunting before it came underprotection in 1989. However, by 2009, its population numbered about 250,000, and rockmonkeys began causing much damage to farmers’ crops. To drive them away, farmers havebeen trying various means that include building electric fences and capturing them. Even so,few farmers have actually harmed these animals. Some farmers do not mind sharing their cropswith the monkeys, but most of them are upset by how the monkeys ruin the crops. The monkeyshabitually throw away a fruit after several bites and then help themselves to another piece;sometimes, they pluck fruits which are not ripe yet.With the removal of the rock monkey from the rare species category, farmers may nowseek government approval to destroy troublesome monkeys. However, this will not preventfuture conflicts between farmers and monkeys, which involve a bigger issue. To begin with,humans move into the living environment of rock monkeys and plant crops. As time goes by,these animals get used to humans, and may sometimes attack humans if threatened. Undoubtedly,monkeys cause damage to farmers, but humans disturb the life of the monkeys as well. After all,the issue of balancing human needs and wildlife is never an easy one.
