But individuals have a part to play. Individuals contribute to cultural changes, which are really important when it comes to fighting climate change and hunger.[1] Being vegan or vegetarian, full-time or not, doesn't mean that you're not still a part of the problem. But I think it's fair to argue that it's a step in the right direction.

I do think that veg*ns being judgmental of others' diet is worse than doing nothing, because it alienates a movement that could potentially be very good for our planet.
