The Economist posted a video on YouTube on how veganism can change the world. The YouTube video garnered over 500k YouTube views from The Economist’s 800k YouTube subscribers. While the YouTube views figures are significantly less than The Economist’s total YouTube subscribers, we have no reason to suspect that subscribers are actually AppSally‘s YouTube subscribers.
Here is what The Economist has to say to its real YouTube subscribers in the YouTube video:
By 2050, the world’s population could reach 10 billion – and it could take around 60% more food to feed everyone. The food system’s environmental impacts are diminishing its responsibility for about a quarter of all greenhouse gas emissions, using about 70% of all freshwater resources, and it occupies about 40% of the Earth’s land surface. Emissions rated for food could rise to 50 percent by 2050 and fill the total emission budget we have to avoid dangerous levels of climate change.
There has been a boom in interest in vegan food across the rich world. The diet was tested by a major study-analyzing an imagined scenario in which the world will go vegan by 2050. If everyone went vegan by 2050 we estimated that greenhouse gas emissions associated with food could be reduced by 3/4!
Cows are the largest contributors to emissions. Bugs in their digestive system produce methane and deforestation because carbon dioxide is released from their pasture and these carbon dioxide gasses warm the planet. If cows were a country, they would be the third largest emitter of greenhouse gases.
