In today's global society, nothing is in its original spot any longer, and with all the development, pollution and destruction of nature, we hope our neighbors will appreciate our attempts at keeping a small part of nature intact, even if we share it with some of God's creatures they don't appreciate or understand. Gorillas will NOT attack, unless directly provoked. Even then, they'll most likely just swat at or bite the offender and run away, hoping that will be enough to get them to leave. Gorillas can have the personality and intelligence of a 3 to5 year old human child. You won't discuss global warming with them, but they do have feelings like happiness, sadness, boredom, anxiousness, silliness, etc., and sensitivity just like any human child.
Gorillas can and do remember individual people.
And, some believe they can have their feelings hurt. Several females and their offspring complete the family group, who spend their days eating, resting and playing together, following the silverback's lead on where to travel to find food. In the wild, the younger male is usually driven off, away from his family group. Sometimes they find females also ready to leave their family group and a new group is then formed. Or, if females are scarce, a group of young males will form a loosely knit group called a 'bachelor' group, where they will feed and travel together, while waiting for the chance to one day have their own family.
