Giraffes average an height of aroudn16-18 ft. I think they look taller than that but that’s just me. They consume a whopping 100 pounds of leaves and twigs a day. I for one cant imagine eating that much, let alone it being leaves. Ive tried eating vegetarian for a day and came to a conclusion that 3 meals a day was not enough. Ive heard once before that vegetation has 100% or so energy and as the consumer eats the leaves, energy is lost cause their body is consuming the leaves. Then, when another animal or human eats the animal that ate the leaves, it loses even more. But that being said, I felt way more satisfied and energized after eating a nice piece of steak. 🙂
