There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Kale, lentils, and other vegan sources such as soy have plenty of protein themselves, but these are mainly what humans eat. I would assume most herbivores eat protein-depleted vegetation, and also as an example, carnivorous bears absorb more protein and size than one that don't eat as much meat, primarily due to most of their vegetation being protein-depleted.
