    That makes no sense just because one thing is taller and weighs more but can only lift 200kg vs a another living thing that is shorter and weighs less but can lift 300kg does it make the taller heavier living thing wrong max amount of weight they can lift makes one of them stronger than the other get what I said is it clear this is for whoever wrote that gorilla versus grizzly bear or vice versa strength against against each other that made no sense the bite force stronger stronger Just because big Grizzly is heavier and taller does not make it stronger I’m a marine biologist I don’t even study land animals and I know that much

  2. IT seems that when a bear charges a human, they kill the human quickly.wikipedia has a listing of maybe a hundred fatal attacks on humans . Can going for a walk in the woods be like russian roulette. Cyclists, hikers, hunters,fishermenonrivers,campers,,outdoor hobbyists all need better answers.

  3. most bear articles, say bear are omnivores, at the same time they say bears travel hundreds of miles to find food,referring to black bears, living mostly in boreal forests,Why travel far for food if theyare predominantly omnivores, there is grass everywhere..if we post comments there is now way to follow up. It seems emails are not acknowledged.
