Answer:
You have changed your environment.
Explanation:
You can't resist not buying a pop whenever you pass in front of a vending machine. You know it's unhealthy to consume a pop this often, but you can't avoid the vending machine that's on your way. One way to avoid this is to change your environment, that is, to avoid walking the path that has vending machines, but instead taking a different path, a different environment that does not have vending machines that influence you to buy a pop.
