Solve greed and you'll have solved the most serious blight on the face of the earth. Everyone becoming vegan is like putting a nice big Disney plaster on the problem but it won't solve the underlying issues. Get everyone meditating 30mins a day and you'll naturally see some pretty radical shifts towards positive sustainable human lifestyles. Veganism is a noble cause but its the underlying mind shift that would be motivating that choice which is actually needed. Horse before the cart. Vastly less meat consumption would be a good solution, limiting the farming of farm animals to only those that can be treated in a humane manner would be sufficient to bring the whole industry down to sustainable and decent levels. Ie ban feedlots, caged animals in tiny coops, factory farming etc.
