Close up of lion cubs in cage\u003cbr/\u003eMany animal and plant species around the world are endangered and face extinction. \u003cbr/\u003eBut, at the same time,  zoos and animal safaris around the world are also struggling with overpopulation problems of some species.\u003cbr/\u003eAs Horizons recently reported one zoo in Ethiopia has resorted to poisoning some of its lion population because they can no longer afford to look after them.\u003cbr/\u003eIn a more humane move a zoo in Israel has decided to use human contraceptives to solve a baby boom in their chimpanzee group. \u003cbr/\u003eThe Zoological Centre Tel Aviv - Ramat Gan is controlling the fertility of two of its female chimpanzees (chimps) using IUDs (intrauterine devices).\u003cbr/\u003eThe zoo says for the time being they want to make sure that no more babies are born into the chimp group. \u003cbr/\u003eThey currently have a community of ten female and two male chimpanzees, which zoo spokesman Mori Erzenstein says is more than enough for the enclosure.\u003cbr/\u003eAuthorities say they have chosen to use an IUD because the process is reversible.\u003cbr/\u003eMethods such as neutering and spaying are not so popular because they're irreversible and often permanently change the animals' behaviour.\u003cbr/\u003eBirth control in zoos and safaris wasn't as relevant years ago when animals were kept in cages and the genders could be separated.\u003cbr/\u003eBut zoos now prefer naturalistic enclosures, allowing animals to display behaviours typical of those the wild. \u003cbr/\u003eZoos around the world are now getting better and better at animal birth control, and many have introduced human-style birth control, including the pill, hormone implants and birth-control vaccines. \u003cbr/\u003eZoo keepers in Ethiopia have recently resorted to more drastic measures to control their rare Abyssinian lion population.\u003cbr/\u003eIn a controversial move zoo officials have been poisoning many cubs and fertile adults to prevent the zoos lion population from getting any bigger.\u003cbr/\u003eKeyword-animals- conservation
