Ok but a “plants only” diet is not a sustainable or natural diet for humans. Humans are not currently enmasse eating a carnivore diet either.
So you are putting forward the argument and problem - that we are currently omnivores and we should not be eating meat , due to environmental concerns and because it lowers the quantity of food we can produce overall.
You are saying it would be better if we all became vegans, so that higher quantities of food could be produced.
You think this is the solution.
The problem with going to an extreme position like you have done is that people will overall get sick from this unnatural diet.
We see thousands of people on Reddit have cured their “incurable auto immune” diseases by going carnivore and not ingesting any plants. After they previously ate too much plants and damaging their intestinal lining resulting in natural plant toxins created by plants to stop insects eating them , pesticides , fungicides, herbicides , glysophate etc leaking from the gut into their blood causing the cykotine response by the immune system and a build up of these toxins around the body (joints mostly with specifically it being the knees for rheumatoid arthritis and such).
Meat is clean of toxins as like in our own body , the animals bodies keep the blood clean of it , any toxins in the blood would cause the animal itself to get sick.
This is not the case at all regarding plants which are full of an assortment of toxins.
We have proof from thousands of individual case reports and published medical papers now that plants are making people sick. The medical establishment simply has not yet put all the findings together or discussed it properly.
Have some common sense. Vegans are sickly, weak and over time they turn into cucks (our personality
Is just a manifestation of our physical state). Carnivores are strong, fit predators.
You’re talking about marketing problems , that’s a real marketing problem for you. Try selling this vegan and bugs diet to the masses. These are secondary problems (marketing) that don’t really have a place in our discussion.
