Can vegans save the world?

What if vegans were the last hope for mankind? Would you stop tucking into your rib-eye steak? Or would you fire up the BBQ? We hit the streets of London to find out!


According to the United Nations, world population has now reached 7.4 billion people. To give you some comparison, in 1959 there were 3 billion of us. Meaning we've more than doubled our population in less than 60 years.

And it doesn’t look like we’re going to stop growing any time soon.

In fact, according to United Nations World Population, the current world population is growing by approximately 74 million people per year. In other words, combine the entire population of Portugal, Spain, Belgium and Ireland and that’s by how many people we’re growing each year.

Problem is, today one in nine people in the world do not have enough to eat (ref: The Hunger Project).

In case you're asking yourself what has population growth got to do with eating animal products or not, well, according to current projections the world population of humans will reach an estimated 9billion in 2040 while some predict it will be as high as 11billion by 2050.

And as the meat and dairy industry use 1/3 of earth's fresh water supply (ref: PNAS) while according to the International Livestock Research Institute, livestock covers 45% of the earth's total land, needless to say that we’re currently facing a pretty big problem: More humans on earth means we need more land to grow more food as we have more mouths to feed.

Problem is, we don't have more land.

And if you look at the numbers, it doesn’t matter if you’re vegan or an avid carnivore, you can’t ignore the fact that we’re heading for a global food crisis, as our current agriculture production will not scale to feed 9+ billion people.

Question is then, what can we do? Or, who can help us save the day? One option could be, vegans...

That’s why in today’s video we hit the streets of London to find out if people are aware that the hope of humanity may actually lie in the hands of vegans.
