In my opinion, the only advantage is that endangered species will be given thechance to reproduce and their numbers will increase. Apart from that, I disagreewith any animals being caged or kept in even a very large fenced area. However,it doesn't take a genius to realise that there are people (poachers) out therethat will do anything to kill off these precious animals for money, endangered <span>or not. </span>
Negative growth rate is when a population's average number of deaths is greater than its average number of births. Zero growth rate is when the average number of deaths equals the average number of births.
