My current diet, I do not wish to state. However, I was a vegetarian in some phases of my life. If motivated enough, I could be a vegetarian for life. However, it would be a folly if I were to start believing that everyone can make sacrifices of this kind. For some people, giving up on things they like to eat is very hard. For some, giving up on using their car is hard. People can do different things to help and not everyone needs to do every single thing. An extreme approach is not practical and it's next to impossible to "sell" such an idea.
