There is a lot of information available about sustainability and the environment, with more and more of it all pointing towards the same facts. These are that a vegan plant-based system is achievable worldwide, uses less resources, cause less GHG (Green House Gases), use less land, has a lighter impact on the oceans and a whole host of other more beneficial reasons than using a system that invloves animal products.
Sustainability is very complex because there are so many variables and so many different ways to produce foods and different land uses. So someone who only eats road kill or found dead animals will create a low impact on the environment and a vegan forager would also create a low impact. But these are rare outliers and are not realistic for a world population of around 7.6 Billion humans.
