Why some grizzly bears look like giant black bears?

For example. Dogs that look for drugs the police in Spain use pigs to look for drugs the navy use dolphins as aquatic soldiers to place mines even kill and wild dolphins are known to have helped and rescued many people from drowning or from sharks . In Asia they use pack rats to harvest wild rice by building a storage with a door so after the rats have filled up the underground store .

The human raid it through the door from above . Dogs help ,blind ,and deaf people ,also for hunting ,protection,guarding ,searching ,pulling ,carrying ,rescuing ,eating etc. then there are ,donkeys ,elephants(help logging and travel and pack),horses ,mules ,lamas ,bufalos,oxen ,camels that carry and pull a great variety of things ,from water wheels to dessert travel eagles or falcons are used to hunt so have cheetahs , ostridges as guards or for riding and pulling we use snakes to control rat populations wasps to kill caterpillars chickens ,iguanas ,chooks ,partridge Guinea fowl to kill garden pest as a biological pestcontrol,on the ground and flying birds to eat caterpillers on the fruit vines pigs to clean up orchards or to plow difficult land by having a moveble coral and the pig churns up the ground ,where there is difficult terrain with snakes and rocks or deep rooted grass ,this is a pig tractor a chicken tractor is used for easier ground ,to get rid of the weeds here on the walls in the tropics we use click clacks (small lizards ,)to eat the mosquitos people use mongoose to root out snakes cats to keep the mice down Carier pigions to relay messages the list is endless and so are the uses.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
