In recent years, there have been a lot of professional surfers who have become more outspoken about adopting a plant-based diet; some have even identified themselves as vegan surfers. If nothing is done, the environmental impact of meat production can only increase. More on Environment. In a week, the average UK citizen chomps through about 1. Grazing cattle accelerate soil erosion, choking off streams and wetlands. In November , 15, world scientists signed a Warning to Humanity calling for, among other things, drastically diminishing our per capita consumption of meat. Animal manures can revitalise the soil and millions of animals live on marginal land that is quite unsuitable for crops. Take the strange case of two vegans in an Italian study who were found to have an environmental impact considerably higher than many meat-eaters. Save water.
I f we really want to reduce the human impact on the environment, the simplest and cheapest thing anyone can do is to eat less meat. Behind most of the joints of beef or chicken on our plates is a phenomenally wasteful, land- and energy-hungry system of farming that devastates forests, pollutes oceans, rivers, seas and air, depends on oil and coal, and is significantly responsible for climate change. The way we breed animals is now recognised by the UN, scientists, economists and politicians as giving rise to many interlinked human and ecological problems, but with 1 billion people already not having enough to eat and 3 billion more mouths to feed within 50 years, the urgency to rethink our relationship with animals is extreme. We humans eat about m tonnes of animals a year, twice as much as we did 30 years ago. We mostly breed four species — chickens, cows, sheep and pigs — all of which need vast amounts of food and water, emit methane and other greenhouse gases and produce mountains of physical waste. But how much stress does our meat-eating put on ecological systems? The answer is a lot but the figures are imprecise and disputed. The authors of the report, called Livestock’s Long Shadow, did not just count the methane from the belching, farting cattle, but the gases released from the manures that they produce, the oil burned taking their carcasses to markets often thousands of miles away, the electricity needed to keep the meat cool, the gas used to cook it, the energy needed to plough and harvest the fields that grow the crops that the animals eat, even pumping the water that the cattle need. Should you include all the knock-on emissions from clearing forests? What about the fertiliser used to grow the crops to feed to the animals, or the emissions from the steel needed to build the boats that transport the cattle; or the “default” emissions — the greenhouse gases that would be released by substitute activities to grow food if we were to give up meat? And is it fair to count animals used for multiple purposes, as they mostly are in developing countries, from providing draught power to shoe leather or transport, and which only become meat once they reach the end of their economic lives?
