 There are just three rules for taking wildlife selfies, but breaking them has even worse consequences than you think. Not only can people food be bad for wild animals, but the more comfortable they become with humans, the more aggressive and dangerous they might be. No matter how cute or sweet it seems, wild animals never benefit from being touched by untrained people. They can also carry dangerous diseases that can spread to you. Invading an animal's personal space can lead to everything from emotional stress to lower birth rates. Not to mention the physical damage they can do to you.
