“Dad, how can you call yourself an environmentalist, and still sell meat?”. First one daughter, then the other, then even my previously carnivorous sons joined in. Their epiphany was brought on by the documentary Cowspiracy; it is smug, irritating and outrageously one-sided in its selection of evidence and ends with an unjustified and ill-considered swipe at Greenpeace. However, despite my irritation, I would agree (uncomfortably for someone selling meat) that no thinking person can reasonably claim to be an environmentalist, or even a humanist, while continuing to eat more than very small amounts of animal protein; most forms of animal agriculture are simply wrecking our planet.
Climate change-wise the arguments are complex, involving ruminant methane emissions, deforestation for grazing and soya production, methane and nitrous oxide emitting manure heaps and soil, intensive versus extensive farming methods and more. As our planet is so diverse in soils, topography, ecology, diet and agricultural methods, it’s unwise to be dogmatic anyway. However, after weeks scouring scientific papers, we have reached the following initial conclusions:
- Livestock agriculture contributes 10-12% of manmade climate change; arguably as much as every car, plane, truck and ship on the planet.
- Livestock agriculture is grossly inefficient and requires 5-10 times more land to feed ourselves than a vegan diet; there just isn’t enough land to go round. OK it’s not that simple; there may well be a credible argument for animals grazing permanent pastures on land unsuited for growing crops for humans, to produce high quality, high welfare meat and dairy, as with most organic farming, but we will have to eat much less of it.
Alongside this are all the health, animal welfare, pollution and antibiotic resistance arguments against eating meat; hard to quantify, but very real. There will be exceptions, but the general conclusion is inescapable; for the good of us and our planet, we must collectively eat much less animal protein. Over the coming weeks we’ll be exploring the issue and suggesting ways to nudge any committed carnivores away from some of their meat. I hope you’ll feel compelled to join us.
It’s hard to argue against this Guy. As a family we are eating less meat but better quality and discovering a love for lentils!
