The ovals aren't really necessary, they are just highlighting the tan areas compared to green.
A common veganism ideal is the belief that you can't feed the world's growing population with animals. It's like they think meat eaters eat nothing but meat. A large percent of the land on Earth cannot be used to grow crops, but can be used to graze animals. Do we just let that land sit empty? Now consider the fact that grazing animals have a positive effect on soil health and help return carbon to soils (neutralizing or reversing climate change). Watch this TED talk with Allan Savory for more on reversing climate change with grazing animals:

If we establish that a large % of the land is only suited for animal production, and those animals can have a positive impact on the environment if managed properly, then we are left with a moral question of whether its okay to kill and eat animals. I would argue that those grazing animals live a better life than they would find in the wild. They have food to eat, are largely protected from predators, are cared for when sick or injured, and are dealt an instantaneous/painless death. Compare that with their wild counterparts. Food can be in short supply, they might starve to death. If they get sick they will probably die, If they break a leg, they will die. And how will they die? They will get eaten alive. Animals don't just die peacefully from old age like vegans seem to think. The only downside from an agriculturally raised pastured animal and their wild counterpart, is the agriculturally raised animal is likely to live a shorter life.
This is why the vegan narrative is bogus. They should be directing their passion and resources to ending the abomination that animal feedlots are.
