BOSH! How to Live Vegan. Henry Firth

feed themselves. If all grain were fed to humans, we could feed an extra 3.5 billion people.[59]

      As Oxford University’s Joseph Poore explains, fossil fuels represent about 61% of today’s emissions.

      Some estimates say as much as 40% of historic global warming is caused by forest clearance that was undertaken to make way for animal agriculture.

      Currently, 25,000 species are threatened with extinction because of agriculture. Freeing up the land given over to animal farming will take some of this pressure off the global biodiversity crisis.

      It will also reduce our nitrogen and phosphorus pollution, and will reduce acid rain by about a third.

      A plant-based diet will reduce the amount of water we need to produce our food by 25%.[60]

      Yes, there are exciting developments in lab-grown meats and these could herald cheaper, less cruel forms of meat production. Many people are also big advocates of insect protein, although the morality of farming and killing gazillions of insects is still not in line with our moral standpoint. And both are still mildly processed, lab-made foodstuffs.

      What about soy then? Soy is a great source of protein for those on a plant-based diet, although it is also the main cause of rainforest deforestation, which is being torn down to provide land to support it. This is an argument often used by anti-vegans, but let’s remember that while around 70% of the world’s soy is fed directly to livestock, only 6% is turned into human food.[61] (See over the page for more on soy.)

      In short, moving to a more plant-based diet is better for the planet and will reduce emissions. It will free up more land, which can then be rewilded and start to draw down carbon and solve our biodiversity crisis. And all the grain and soy which is currently fed to animals can be used to help feed the poorest nations. And the water which is not used for rearing those animals can be used for irrigating crops.

      Of course, we appreciate that it is all far more complicated than that. There are good farms and bad farms. And conditions and practices differ all across the world. We all know people who keep chickens as egg-laying pets, and we can’t really compare them with a 1,000-strong battery farm where chickens never see the light of day.

      There are bad ways to farm vegetables too, and we’re not advocating a move to more monocrops.

      However, ultimately, wherever your meat, fish or dairy is coming from, it is a less environmentally friendly choice than any plant-based food.

      A plant-based meal is more sustainable than one containing animal products. And so, the more plants you eat, the better.

       SOY

       IS IT BAD FOR ME, AND IS IT BAD FOR THE PLANET?

      Depending on who you are, you might see soy as either a wonderful health food or a risky ingredient to be avoided. And as far as the planet is concerned, there are differing opinions about how soy for humans is affecting the health of the planet. Some see it as the cure-all for our planet’s woes, and some see it as the cause of rainforest deforestation. Let’s delve into them both.

       Soy is, on balance, a health food.

      Some people, as part of some research from the 90s, formed the opinion that soy could be bad for your hormonal health. They drew inferences from the fact that soy contains oestrogen-like compounds and speculated that it could mess with the hormonal balance of both women and men in different ways. These studies have largely been disproven now, and recent research shows that moderate consumption of soy foods can actually have some benefits.[62] Even a correlational relationship is not maintained, so largely we know this is not the case.

      On the other hand, soy is a very powerful and healthy plant-based protein. It’s a complete protein, containing all the nine essential amino acids we need in our diets (see here for more on these). And it’s a good source of omega-3 fats, iron, zinc and calcium.

       Soy fields are a cause of rainforest deforestation, but this soy is grown for animal feed.

      Significant amounts of the Amazonian rainforest are being destroyed every day, and these trees are crucial to our planet’s survival. They are the lungs of our planet, and their loss is a significant factor in contributing to climate change.

      A large amount of the rainforest deforestation occurs to make way for large, monocrop soy fields. This has been used regularly to illustrate that vegans’ choice of soy milk is poor. But that’s not the full story!

      Eighty per cent of the soy that is grown in the Amazon (the soy for which the rainforests are being destroyed) is fed to animals, [63] and indeed up to 90% of the rainforest’s total deforestation is for animal agriculture.[64] But as we’ve seen, only 6% of the soy produced globally is consumed by humans.[65] So, while it is true that the megafields of soy are causing mass destruction of the rainforest, it’s the animal agriculture industry that is causing it and utilising the soy.

      Also, when comparing the environmental impact that soy has on the planet versus an animal-based protein like beef, you should take into consideration all the soy the animal has consumed as part of its lifecycle. When framed like this it seems silly to compare the two. Rearing an animal is a much less efficient way to get protein, with only a fraction of the energy that is fed to the animal as plants being available to humans as meat. (See here).

      So, despite what many people would have you believe, you should feel free to consume soy with a clear conscience, from both a health and environmental perspective. It’s good for your body and is much more environmentally friendly, when you look at all the factors involved, than eating a comparable animal protein. Miso, soy sauce, soy milk, edamame, tofu and tempeh are all wonderful choices for you to include in your diet. We highly recommend getting on board with soy. It doesn’t deserve its bad reputation, and in fact is part of the solution to the planet’s ills, not part of the problem.

       CAN I REALLY MAKE A DIFFERENCE?

      When we told our friend Naushard we’d gone vegan, he exclaimed that he’d found a flaw in our plan. He discovered that the motivation was climate change. And so, with a devilish look in his eye, he told us jokingly (or not jokingly) that for every steak we didn’t eat, he was going to eat two steaks!

      Great banter. Naushard is a funny guy. But let’s delve into his threat for a moment. Not only did he not buy into our logic about cutting out meat having a positive impact. He didn’t think that our not eating meat was going to make any difference at all. But he was also threatening to ensure that our change didn’t make any tangible difference anyway, by upping his meat intake to counter our meat decrease. Funny. And kind of evil.

      The last time we saw Naushard, we were shocked to hear that he had given up meat. ‘I don’t eat steak anymore. I’m still eating fish, but no more steaks.’

      To hear him backtrack was a genuine shock. He is the last person you would expect to go back on his word. He would prefer to keep the joke going at the expense of the truth if it made it funnier. And here he was admitting that he had not only broken his promise, but had done a total about-turn and joined us in the beef-free camp!

      We see this all the time. We love it and it’s one of the best things about our job. Talk to any vegan, and they’ll have a story like this one. And it goes to show that you really do make a difference to those around you. We all affect
