Dan is camping in the woods with some friends. They wake up early the next morning to go on a hike to see the sunrise on a mountain peak. They have food out from breakfast and don't want to take the time to put it away because they are running late. Dan decides to just take all of the food and put it in Paul's tent, without sealing it up in anyway. He tells everyone he will seal it up when they get back.

Dan does not realize that Paul is still in the tent sleeping in his sleeping bag. Dan thinks Paul is with them on the hike.

A bear smells the food, bursts into Paul's tent, and badly mauls Paul while eating the food.

Assume that the standard practice for hikers and food is to keep it in sealed containers and store it away from the campsite.

Did Dan breach a duty of care to Paul? Why or why not?
