We need to eat less meat - and the G8 should say so

Instead of feeding starving humans, we funnel huge amounts of crops through the animals we use for food. G8 leaders must call for change at next week's summit.

In Davos this April, David Cameron outlined his priorities for the UK's presidency of the G8 this year. He talked about advancing trade, ensuring tax compliance and promoting greater transparency, all with the goal of creating "lasting global prosperity". It's a noble goal – lifting people out of poverty and making corporations accountable for their actions. It's reassuring to see these issues receive international attention.

But there is one obvious issue that is not being talked about, which should be at the top of the G8 agenda: animal agriculture and its contribution to world hunger, environmental degradation and skyrocketing healthcare costs, all of which affect the global economy.

There is more than enough food being grown around the world to feed the entire human population. So why are more than a billion people going hungry? Because instead of feeding starving humans, we funnel huge amounts of crops through the animals we use for food. It takes up to 16 pounds of grain to produce just 1 pound of meat. And an astounding 97 per cent of the world's soya crop goes to farmed animals rather than to hungry people.

We could eliminate the worst cases of world hunger with about 40 million tonnes of food. And it would be easy enough to find: nearly 20 times that amount of grain, 760 million tonnes, is fed to animals on factory farms every single year. Compare this to biofuels, which account for only 100 million tonnes. Tens of thousands of people marched in London on Saturday in support of Enough Food IF, a laudable campaign which highlights biofuels as one of the "bad guys" in the fight to end global hunger – and yet, inexplicably, it doesn't have animal agriculture as one of its key themes.

By cutting our meat consumption and slowing the rate at which animals are bred, we could redirect the crops that they would have consumed to the people who need them most. That's why the prestigious Worldwatch Institute maintains that "[m]eat consumption is an inefficient use of grain – the grain is used more efficiently when consumed directly by humans. Continued growth in meat output is dependent on feeding grain to animals, creating competition for grain between affluent meat-eaters and the world's poor". Therefore, raising animals for meat creates a disturbing social-justice issue.

And as meat-based diets spread to developing countries, subsistence farmers are being driven off their land. Efficient, plant-based agricultural models are being replaced by intensive animal agriculture, which also pollutes the air and water and leads to desertification that renders the once-fertile land barren.

The United Nations reports that the meat industry is "one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global". And it's easy to see why. Carbon dioxide, methane and nitrous oxide are the principal agents of climate change – and raising animals for food is one of the largest sources of carbon dioxide and the largest source of both methane and nitrous-oxide emissions. When you add up all the energy-intensive stages of raising animals for food, slaughtering them and processing and storing their flesh, it's clear why producing 1 calorie of animal protein requires more than 11 times as much fossil fuel as producing 1 calorie of plant protein. In addition, Greenpeace estimates that in a single crop season, more than 2.9 million acres of the Amazon rain forest in Brazil are destroyed to make more room to grow crops to feed farmed animals.

The water footprint of the livestock sector is also huge. It takes more than 2,400 gallons of water to produce 1 pound of meat, while growing 1 pound of wheat requires only 25 gallons. You save more water by not eating a pound of meat than you do by not showering for six months!

Not surprisingly, the United Nations Environment Programme concluded  that "[a] substantial reduction of impacts would only be possible with a substantial worldwide diet change, away from animal products".

Environmental issues, in turn, have a serious impact on our economy. Heat waves, droughts, rising sea levels and other problems caused by climate change can ruin crops and result in increased food prices. Major storms, a developing trend that scientists have also linked to environmental destruction, often do billions of pounds in damage. Sir Nicholas Stern, author of the government-commissioned review on climate change, which has been the reference work for politicians and journalists throughout the last 10 years, warns that if we do not reduce greenhouse-gas emissions, it will take less than 40 years for climate change to cause up to a 20 per cent drop in the world's gross domestic product. He fears that it could be "market failure on the greatest scale the world has seen".

Then there are the skyrocketing healthcare costs that are attributable in large part to the increase in human consumption of meat, eggs and dairy products. Loaded with artery-clogging cholesterol and saturated fat, these products have been linked to cancer, heart attacks, strokes, diabetes and obesity. These top killers burden the National Health Service and necessitate that billions of pounds be spent searching for cures and medications to relieve disease symptoms. They also claim a huge number of lives.

Aside from their environmental and health impacts, the meat, dairy and egg industries cause immense suffering to more than a billion animals every year in the UK alone, most of whom spend their entire lives crammed inside dark, filthy sheds. They don't get to breathe fresh air until they are on their way to the abattoir, where many have their throats slit while they are still conscious.

"Lasting global prosperity" can be attained only through sustainable growth – otherwise, we will simply compound current environmental and economic problems. World leaders at the G8 Summit must take into account the devastating impact of animal agriculture in order to encourage global food changes that will be the catalyst for such growth.

Theresa May’s stage-managed election campaign keeps the public at bay

Jeremy Corbyn’s approach may be chaotic, but at least it’s more authentic.

The worst part about running an election campaign for a politician? Having to meet the general public. Those ordinary folk can be a tricky lot, with their lack of regard for being on-message, and their pesky real-life concerns.

But it looks like Theresa May has decided to avoid this inconvenience altogether during this snap general election campaign, as it turns out her visit to Leeds last night was so stage-managed that she barely had to face the public.

Accusations have been whizzing around online that at a campaign event at the Shine building in Leeds, the Prime Minister spoke to a room full of guests invited by the party, rather than local people or people who work in the building’s office space.

The Telegraph’s Chris Hope tweeted a picture of the room in which May was addressing her audience yesterday evening a little before 7pm. He pointed out that, being in Leeds, she was in “Labour territory”:

But a few locals who spied this picture online claimed that the audience did not look like who you’d expect to see congregated at Shine – a grade II-listed Victorian school that has been renovated into a community project housing office space and meeting rooms.

“Ask why she didn’t meet any of the people at the business who work in that beautiful building. Everyone there was an invite-only Tory,” tweeted Rik Kendell, a Leeds-based developer and designer who says he works in the Shine building. “She didn’t arrive until we’d all left for the day. Everyone in the building past 6pm was invite-only . . . They seemed to seek out the most clinical corner for their PR photos. Such a beautiful building to work in.”

Other tweeters also found the snapshot jarring:

Shine’s founders have pointed out that they didn’t host or invite Theresa May – rather the party hired out the space for a private event: “All visitors pay for meeting space in Shine and we do not seek out, bid for, or otherwise host any political parties,” wrote managing director Dawn O'Keefe. The guestlist was not down to Shine, but to the Tory party.

The audience consisted of journalists and around 150 Tory activists, according to the Guardian. This was instead of employees from the 16 offices housed in the building. I have asked the Conservative Party for clarification of who was in the audience and whether it was invite-only and am awaiting its response.

Jeremy Corbyn accused May of “hiding from the public”, and local Labour MP Richard Burgon commented that, “like a medieval monarch, she simply briefly relocated her travelling court of admirers to town and then moved on without so much as a nod to the people she considers to be her lowly subjects”.

But it doesn’t look like the Tories’ painstaking stage-management is a fool-proof plan. Having uniform audiences of the party faithful on the campaign trail seems to be confusing the Prime Minister somewhat. During a visit to a (rather sparsely populated) factory in Clay Cross, Derbyshire, yesterday, she appeared to forget where exactly on the campaign trail she was:

The management of Corbyn’s campaign has also resulted in gaffes – but for opposite reasons. A slightly more chaotic approach has led to him facing the wrong way, with his back to the cameras.

Corbyn’s blunder is born out of his instinct to address the crowd rather than the cameras – May’s problem is the other way round. Both, however, seem far more comfortable talking to the party faithful, even if they are venturing out of safe seat territory.
