Lions are meant to hunt and kill animals and must do so regularly to survive. They are part of a balanced ecosystem.
Man is meant to eat a variety of foods depending on what is available to him. Omnivores can help maintain an ecosystem if one species is becoming extra prevalent.
Man, however, has greatly disrupted almost every ecosystem worldwide. The ecological impact of raising cattle and other animals, genetically engineering crops and selectively breeding animals is quite profound.
How we define what is ethical in these constraints is largely arbitrary. If you accept that tinkering with the ecosystem in such a way is wrong, then you have much larger concerns than diet to worry about. That being said, there is nothing wrong with feeling good about yourself for making sacrifices to (even slightly) lessen your ecological burden on this world.
