Ok so here’s the deal: in 30 years the world will be eating a mostly vegan diet.
Before you say I’m crazy, let’s just look at the facts:
Animal agriculture contributes 51% of total global greenhouse gas emissions. It’s responsible for 91% of Amazon deforestation, and 1-2 new acres are cleared every second. One third of all freshwater globally is used by the meat and dairy industry. A vegan can be fed on just 1/16th of an acre of land for a year while a meat eater needs 18 times that much land, and waste and pollution from animal farms are an environmental catastrophe, leading to ocean dead zones.
If we accept those fact then we can say this with certainty: animal agriculture is unsustainable.
