The population of white-tailed deer(白尾鹿) is growing rapidly in many parts of the United States. As the population grows, food becomes a problem. Many deer die of hunger. Others grow up to be small and unhealthy. To search for food, hungry deer move closer to where humans live. They eat crops, vegetables and even trees. Besides, there is a large number of deer near roads. It can cause traffic accidents. People admire the grace and fast speed of deer. Most people don't want these animals to be hungry or ill. Should people take action to control the growing population of deer?
Should People Take Direct Action?
Many people think that hunting is the best way to control the population of the deer. Wildlife managers will see if there's enough food in an area and decide its carrying capacity(容量). Then hunters with licenses are sent to help control(控制) the number of deer. Hunting is usually not allowed in cities or the suburbs(郊区). However, some people have the idea of catching the deer and moving them to other places. But this method is expensive and requires finding another place that can accept the deer without breaking the balance of the ecosystem(生态系统). Scientists are also working to develop chemicals(化学制品) to control the birth rate(率) of the population of the deer. But this plan works for only one year at a time.
Should People Take Indirect Action?
Some suggest bringing in natural enemies(敌人) of deer, such as wolves, lions and bears, to areas with too many deer. But these animals could also hurt dogs, cats, and even humans. Other communities have built tall fences(篱笆) to keep out deer. However, this is impossible for farmers.

Some people are against any kind of action. They support(支持) leaving the deer alone. Animal populations in an area naturally go up and down over time. Doing nothing means that some deer will die of hunger or illness. But finally, the population will reach a size within the carrying capacity of the environment.
So, let nature go its own way.
