If you want to keep wildlife truly wild you should do your part to minimize the impact you have on their habitats and behaviors.
Who says this is changing their behavioural patterns? Maybe native people in north america have been randomly feeding grey squirrels for thens of thousands of years.
Maybe for longer in Eurasia?
In fact if it weren't in the animals behavioural repertoire to recognise the opportunity of taking food from people, then we wouldn't even be able to get them to understand.
Can you guarantee 100% that is isn't? No, of course not. Then just leave them alone. What is it with people feeling they can just constantly interfere with animals lives. These are not your pets, not your playthings to do as you wish.
