Running campgrounds, this is the hardest thing we still have to teach people. Do not feed the wildlife -- you are killing them. Example from Yellowstone:
On Wednesday, Montana biologists euthanized a female grizzly that had taken to eating human food in the West Yellowstone area, frustrating a state bear expert with campers' failure to secure their food, reports The Bozeman Daily Chronicle.
"It is always frustrating to have to make this type of decision and remove a bear for things that could have been basically prevented by people," Montana Fish, Wildlife and Parks bear specialist Kevin Frey said on Thursday.
