According to the uploader, this guy is going to be charged with harassing wildlife, which I guess is fair enough:

Obviously not a cool thing to do but I’d be lying if I said part of me didn’t think that was an awesome little stunt. The moose just shrugged him off into the ocean after a short while — no real harm done right?

I wouldn’t say it’s as brave (or stupid) as the kid who did the same thing to a rhino though.
