Why dont we just exterminate all bears?

Because that would be really hard. Think about all the logistical issues you'd run into.

First off, you'd have to find them all, which would be an absolute bitch all on its own.

Secondly, you gotta kill them all, which would involve lots of guns and dodging the veritable legions of animal rights activists that would no doubt get in the line of fire, and then you've got collateral damage so you have to come up with a really good excuse for mowing down 130 PETA members with an assault rifle.

And I mean a really good excuse. As in, it had better stand up in court or you're not going to get any bear execution volunteers. No volunteers means you have to pay people and thats a whole other can of worms.

Then you have to dispose of all the bodies. Bear corpses are heavy. And lots of them would necessitate the use of trucks. Many trucks. Now you gotta buy fuel. More money again. No one is going to volunteer for this costly expedition.

Dont forget, you have to bury all of those animal rights activists you massacred. Thats a hitch.

Anyways, to answer your question, theres just too many problems associated with it and we really just cant be bothered. Its much easier to just leave them alone. Really, they very rarely harm anyone.
