Your either a producer or consumer, the carbon cycle has a slow geochemical process and a large biological one. Most of the carbon dioxide in atmosphere is fixed by producers and so more consumer biomass more is sequestered in complex diverse ecosystems. We’ve been losing biomass for thousands of years , and domesticated most plants and animals so many wild type extinct- apparently cannabis has been domesticated so long it’s wild type lost. Plants alone don’t cut it - meat is not the enemy - though I agree too much of plant or animal can be problematic. It’s eating a balanced diet of veggie, fruits, nuts and animal protein. All animal protein contains all essential amino acid da needed for protein synthesis , whereas most plants, except busckwhest and quinoa I think are incomplete lacking certain amino acids. Generally it’s easier for humans digestion to absorb proteins , minerals and vitamins from animal sources ( although there is genetic variation in certain populations) . B vitamins especially rich in animal. So you have to really know your plant protein limitation to reach dietary needs eating the varieties needed. I’m sure it’s like lactose intolerance so adaptations to diets promote some genetic differences. I lose weight reducing carbs while my wife loses weight reducing her fat content. Just like genetic disposition to where you gain weight. I think people need to listen to their bodies.I remember one study in children where they gave them a table of options from junk to healthy. Initially they went for junk but over time they ended up eating a fairly balanced diet. There just isn’t one size fits all that just doesn’t fly with genetic diversity and polymorphisms. Really like the US jobbed off much of their carbon footprint to overseas industry we eliminated and limited wild life such the biomass replaced by domesticated ones. We need biomass to sequester more carbon with normal gigaton budgets in our food chains.
