Of course, at different stages people have had different ways of thinking. Today if people are not willing to use hunting as a means of controlling animal populations, many alternatives are available. In the past, elephants were shot in South Africa in order to control their numbers. Today, when elephant numbers rise too high, they are given contraception.
當然，人在不同階段有不同想法，若今天人們無法接受以打獵控制物種族群，那節制過度繁殖的方式還有很多，過去南非為控制大象數量，採取射殺方式，今天對象群的控制，則給予避孕。
