Arnold is known by his great physics and bodybuilding career, therefore, many people look up to him and try to copy his way of living when they are working on their lifestyle. That is why it is such great news that he has decided to stop eating meat. Actually, he encourages everyone to do the same and he has, finally, realised that you do not need meat to get your protein and build muscles.
Hopefully, more people out there trying to build muscle or get in shape get affected by his decision and minimizes their intake of meat. The meat industry is indeed the biggest threat to our planet, so it is about time that people start opening their eyes and do something about it, rather than just having their own needs in focus.
