A note from Ian
I grew up in a reasonably big city. I love cities. I like their vibrancy, the people, the history, the architecture and the energy. Having said this, I also love the countryside. I was lucky enough to spend a good chunk of my childhood in a small (and I mean very small) village called Gunthorpe.
My grandparents, Charlie and Winnie, owned and ran a small arable farm there. I have many fond memories of that farm. The memories mostly revolve around my grandma’s wonderful cooking, but also exploring the old farm buildings and riding around in my grandad’s tractor as he ploughed fields, planted seeds and harvested crops.
I look back now, and realise that my grandfather worked bloody hard. All farmers do. When I say ‘worked bloody hard’ I don’t mean, ‘I got to the office at 9am, hammered out some emails then had lunch, had a meeting, smashed out a couple of spreadsheets and was home for 6.30pm.’ I mean, ‘I woke up at 4.30am, headed to one of my huge fields, smashed out some back-breaking labour until it got too dark to carry on, got home for 10pm, went to bed and hit repeat the next day. Every day.’
I understand how hard farmers work and I’ve got nothing but the utmost respect for their tremendous work ethic. However, having said that, I wholeheartedly believe that some of the practices used in farming need to be re-evaluated and reformed. As the UK edges ever closer towards a more vegan way of life, and demand for vegan products grows and demand for non-vegan products declines, it’s absolutely essential we give our farmers the tools, education and incentives they need to adapt and thrive. We need to work with farmers to harness their unquestionable and inspiring work ethic and experience, and include them as a big, important part of the inevitable switch to plant-based living.
We’ve been talking a lot about meat, but we shouldn’t ignore our sea-dwelling friends either.
Half of all marine life has been lost in the last 40 years[51] and 87% of fish populations are fully or over-exploited.[52]
We’ve already killed 90% of big ocean predatory fish,[53]and it’s been predicted that our world will run out of saltwater fish by 2048.[54]
Increasing sea temperatures have destroyed coral reefs and all coral reefs are projected to be lost by 2050.[55]
Fishing is also a grossly inefficient way of eating; for every 1lb of fish caught, up to 5lb of unintended marine species are caught and discarded as by-kill.[56]
FEEDING A GROWING POPULATION
There’s another thing to consider when thinking about the sustainability of our current diets. Our nutritional needs are going to evolve over the next few decades with the human population expected to reach more than 9 billion by 2050 – a third higher than it is today.[57]
So what’s the answer? Meat? No. Increasing annual meat production is a bad idea, however we do it. All approaches will use more land, create more deforestation, more climate change, more loss of biodiversity.[58] Feeding grain to livestock increases demand for grain and drives up prices, making it harder for the world’s poor to 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
