If you do have veg diet, you will have to eat more meals (this is from personal experience, I go veggie twice a month for religeous reasons). You feel hungrier faster, therefore, making you eat more. And people who don't have time can't have more meals. I only think people should become vegetarians only because they don't enjoy meat. I think it's a stupid idea to become vegetarian if you don't enjoy it, talk about throwing your life away. Humans are omnivores, it isn't that simple for us to just eat plant or to just eat animals. We need a balanced diet and therefore both plants and animals. Wolfiera, fish are animals too. They feel pain as well. Whatcha gonna say 'bout that?
Please treat seafood as an animal. This in my opinion, is contradicting your precious peta. Like monty hall said, people only want to rescue cute things. Clams, prawns and fish are all animals. What make you think you're vegetarian when you're taking their lives away?
Oh yeah, are you a vegetarian?
By the way, they are not killed slowly. Livestock get a quick and humane death, it's convinient that way. They can't get shot in the head because it will cause lead poisoning in the meat.
