I don't have a link off hand, but I remember from university a professor showed us how many vegetables you would need to eat to get an equivalent amount of protein from a serving of meat (chicken breast or small steak). You literally need a mountain of veggies to equal the protein provided by meat. The thought was that if we wanted to replace meat protein with veggie protein, then we'd need to cover the earth in soy, edamame, and lentils.
