Going vegetarian is not "easy". It requires ingredients that are not as highly available, and vegetarian meals that satisfy a person's nutrition requirements typically take longer to make. It also cuts down on the variety in the food you can eat, and in most cases, takes a lot of willpower. Of course it would have a huge impact - you're radically changing the diets of a majority of the population of the planet.
