Numbers of monkeys living at an area of middle Africa dramatically fall. That is caused by hunting them, because eat their meat is totally common there. Basically, eat them stems from an old tradition and many people still believe, that Monkeys' meat has miraculous effects. Another fact for hunting monkeys is, that it is much easier than grow own crops on a field. Anyway, only sometimes. One monkey has defied to aboriginal poachers and began protecting yourself. And it evidently upset the poachers. They do not fear sacrifice own lives for getting piece of the monkey's delicious meat. They are so focused on it, that they forgot collect some other food. And some already say, that if they do not get the monkey until 15 days, they will die of hunger. Can you help the monkey with the protection for the time of 15 days? Have fun.
