Should We All Be Vegan?: A primer for the 21st century (The Big Idea)

As concern grows over the environmental costs and ethical implications of intensive factory farming, an increasing number of us are embracing diets and lifestyles free from animal products. Has the time now arrived for us all to reject the exploitation of animals completely and become vegan? Would adopting a wholly plant-based diet be beneficial for our health? How would a majority vegan population affect the global economy and the planet? Does it make any sense to go flexitarian or vegetarian? Molly Watson explores the history, rationale and impact of veganism on an individual, social and global level, and assesses the effects of a mass change in diet on our environment, the economy and our health.
