Test tube hamburgers, and other stories

Artificial meat: closer than you think? Would you eat meat grown in a test tube? If not (and you eat meat), are you satisfied with your knowledge of how your meat is produced?

Air Con: As the world warms, we'll just crank up the air con, right? Wrong. Since 1987, new air conditioners are no longer a threat to stratospheric ozone, but the replacement for ozone-destroying CFCs have been a range of climate-disrupting alternatives, each far worse than CO₂ molecule for molecule: "The leading scientists in the field have just calculated that if all the equipment entering the world market uses the newest gases currently employed in air-conditioners, up to 27 percent of all global warming will be attributable to those gases by 2050."

Land grab: An area of agricultural land larger than Texas in developing nations (80% in Africa) has been bought up by foreign governments and corporations over the last few years, according to a new study from the Worldwatch Institute. Some of this has been European corporations keen to make a profit from biofuels regulations, some has been from large nations with serious and growing domestic food security issues, such as China and Saudi Arabia.

Flatter highlands: At least in biodiversity terms. Climate change is flattening the biodiversity found in the Scottish highlands.

China: The fastest growing economy in the history of humanity is not making a happy nation.

House sizes: Australians have some of the largest houses per occupant in the world. This is a significant part of the reason why we have the highest per capita carbon footprint in the OECD.* Large houses not only require more energy-intensive building materials (concrete and steel are both associated with very high emissions), but - all other things being equal - have larger energy needs than smaller dwellings. It doesn't help that we have one of the most coal-reliant electricity systems in the world.
*And that's even before we consider our imported manufactured goods or our exported coal. We export more coal than any other nation.

Solved: Four significant ecological issues have been adequately addressed since 1992. Only another eighty-six to go.

Fracking: the real danger. I wholeheartedly agree and am glad to finally see someone in the mainstream press pick up on this. There are all kinds of legitimate questions about the safety of fracking shale for non-conventional gas, but the biggest one is most rarely addressed, namely, tapping into this resource massive expands the available pool of fossil carbon we will be moving from safely underground and into the active carbon cycle where it can mess with ocean pH and the climate.

Endangered species: The International Union for Conservation of Nature's (IUCN) Red List is widely regarded as the most authoritative attempt to account for the level of extinction threat faced by the world's species. Species are categorised according to the degree of severity - Least Concern, Vulnerable, Endangered, Critically Endangered, Extinct - yet of all the world's species, the IUCN estimates it has only assessed 4% so far. Of the dangers faced by the other 96% we have as yet little clear idea.

Not with a bang but with a sustained leak

Real Climate: Why Arctic methane release is bad, not catastrophic. This is a very important post. Many have been deeply worried about the possibility of a so-called "methane gun" in which truly staggering volumes of frozen methane clathrates that sit on and under the ocean floor of the Siberian continental shelf are released in a runaway feedback as the Arctic Ocean warms. Since methane (CH₄) has something like 100 times the warming potential of carbon dioxide over a twenty year period, it has been hypothesized that a rapid release of large volumes of stored methane could cause a sudden and likely catastrophic surge in global temperatures. A variation or accompaniment to this scenario is the rapid release of methane from thawing permafrost in Siberia. In the linked post, a senior climatologist argues that it is far more likely that methane release will be chronic rather than acute, and given methane's relatively short atmospheric residency (about ten years), this will lead to a dangerous (though not immediately catastrophic) rise then stabilisation of methane levels, supplementing but not overwhelming warming from carbon dioxide. However, since atmospheric methane gradually degrades to carbon dioxide in the presence of oxygen, a slow release would not only give a bump to methane levels but would also see carbon dioxide levels continue to rise. Unlike methane, carbon dioxide is basically forever, with about half of any increase in atmospheric concentration we experience likely to remain for centuries and about a quarter likely to remain for at least ten thousand years. So a relief (of sorts) for us. It's a bit like finding that the Nazis don't, as feared, have a nuclear weapon, but they do have twice as many conventional forces as was thought.

ABC Religion and Ethics: The New Evangelicals: How Christians are rethinking Abortion and Gay marriage. Despite being published by the ABC, this piece (an extract from a new book) has its eyes on the US scene. How applicable are the trends it identifies elsewhere amongst evangelicals?

Guardian: More farmers needed. Feeding seven, eight, nine, ten billion without strip-mining the soil, using the atmosphere as a carbon dump, squeezing out biodiversity, depleting finite fuels or overloading rivers, lakes and oceans with nutrients requires more organic poly-cultural farming, which can often be more productive per unit of land overall than present industrial monocultural farming. However, it is less productive per unit of labour, meaning more people employed (again) in growing food, which probably means higher food prices and a greater share of incomes devoted to food. This in turn may help address obesity, though at the risk of increasing malnutrition associated with poverty. Hence, addressing inequality is also critical.

Peter preaches on the parable of the talents (Matthew 25.14-30). This passage is often used as a key plank in a justification of usury. There are elements in the narrative and context that suggest a very different reading. Peter highlights the key theological question lying behind this hermeneutical issue: which kind of God do we serve?

McKibben: On being hopefully naïve about getting corporate money out of US politics and why being cynical is hopeless.

Monbiot: The limits of vegetarianism, in which George changes his mind and shifts to ethical semi-vegetarianism. The Conversation publishes an even more provocative piece against ecological vegetarianism, and a very interesting discussion in the comments ensues.

SMH: Energy and water. In the 20thC, global energy use increased thirteen-fold and water use increased nine-fold. The two are related and any future has to consider our water habits, which might be less about having short showers than having cold ones, since energy production is one of the most water-intensive things we do (though conversely, where water is scarce, desalination is one of the most energy-intensive things we do).

On the brink

Mark Zuckerberg, founder of Facebook, has taken a challenge this year to become more mindful of and thankful for the food he eats. As part of this, he now only eats meat which he has killed with his own hands. This is quite a good discipline in order to learn what our diets actually mean.

Thirty-six of the world's forty dolphin species are in trouble. Dolphins have to come close to the top of the list of charismatic megafauna. Many of the other contenders for top place are also in trouble. Lions used to the be the second most widespread mammal (after homo sapiens), found throughout all continents except Australia and Antarctica, but have been hunted to extinction everywhere except parts of Africa and one tiny piece of India. Their numbers continue to drop precipitously: from perhaps 400,000 in 1950 to about 20,000 today.

John Cook: Are you a genuine sceptic or a climate denier? I've been planning a post along these lines for a while btu have never got to it. Now John has beat me to it.

Guardian: Australian ethicist Peter Singer is now leaning towards moral objectivism (that things are right or wrong independently of our desires) due to the difficulties faced by subjectivism in the face of climate change.

Seventeen Nobel Prize laureates and forty other experts warn: "we are transgressing planetary boundaries that have kept civilization safe for the past 10,000 years".

The World Meteorological Organization believes that extreme weather made worse by climate change will (continue to) undermine global food production.

Clive Hamilton argues the case for environmental radicalism. Asking nicely didn't cut the mustard for the suffragettes or the civil rights movement.

Joe Romm lays out the disturbing findings of a Royal Society conference last year discussing the impacts of a 4 degrees temperature rise. This is pretty much where we are headed at the moment with our all too modest attempts at mitigation. Or rather, this is where we are headed within the lifetime of those already born. Our ultimate destination may be far, far worse. This was the conference that convinced Clive Hamilton that it is necessary for us to despair.

Onion: Yet another species on the brink of extinction.

Eat as much of this meat as you like

Here is a meat industry I think we can all give more support to. In comparison to factory farmed meat (i.e. most of what is generally available in supermarkets), this meal has a much smaller footprint.

Why Christians willingly pay taxes...

...and other stories
Why Christians willingly pay taxes: Brad makes a very interesting suggestion for how to read the passage in Romans 13 that speaks about submission to the authorities. Surprisingly, he reads it in the context of chapter 12 and the second half of chapter 13.

Do no evil?: Google dodges over US$3 billion in tax each year.

The Tea Party: an opinionated view. "It would be inaccurate to say the Tea Partiers are racists. What they are, in truth, are narcissists."

Eat less meat: is it so difficult? There is an argument to be made that meat from factory farms is meat offered to idols. But that's an argument for another day.

Things Obama has done. Of course, not all these are unambiguously good and he's done (or not done) plenty of disappointing things as well. He's not the messiah, but neither is he the anti-Christ.

Meaty matters with Monbiot: can we eat meat and be ecologically responsible?

In his latest piece for the Guardian, George Monbiot has retracted an earlier article in which he claimed that veganism (or at least vegetarianism) was the only possibly ecologically responsible diet. Having read a new book by Simon Fairlie called Meat: a benign extravagance, Monbiot has admitted that he has been repeated various statistics that don't add up.

The book points out that the real enemy is not meat consumption or production per se but the ecologically disastrous industrialised meat production that comprises over 95% of all the meat eaten in western countries (and an increasing share of the rest of the world too). Such "factory farms" typically involve grain feeding, total confinement systems with liquefied manure, heavy use of hormones and feeding of antibiotics.
Not only are factory farms worse for the planet, they also generally involve much higher levels of animal cruelty.

And so, ecologically speaking, all flesh is not created equal in its impact. The kind of meat and the methods used to raise it are crucial. For instance, there is a huge difference between eating meat from animals culled due to overpopulation (such as kangaroo in Australia, or venison in Scotland) and eating industrially farmed beef or pork. Similarly, there are huge differences between different fish species, some of which are overfished and approaching extinction, while others are carefully managed.

As I've discussed before, I think there is a strong ethical case for serious reductions in the average meat consumption of westerners. This article has reminded me that it is particularly factory farmed meat that is the real culprit (see also here and this book).
How can you tell if the meat you're eating has been industrially farmed? If you have to ask the question, then it almost certainly is. This piece has some good basic suggestions for how to find non-factory meat.

Three interesting ecological articles

In today's Guardian:

• Western overconsumption more of a threat than global overpopulation.
• Record atmospheric temperatures, ocean temperatures, Arctic melt: 2010 shaping up to be a(nother) scorcher.
• UN report says eat less meat to reduce water consumption, deforestation and carbon and methane emissions.

On this last one, it seems that a consumerist lifestyle has a double impact: directly through our own consumption and indirectly through emulation in the rising middle class of the developing world.

Loving meat: why I am a vegetarian (almost)

"Better a meal of vegetables where there is love
    than a fattened calf with hatred."         - Proverbs 15.17

A vegetarian friend used to quote this proverb in support of her practice. I would then gleefully point out that the proverb assumes the superiority of meat to vegetables in order to make its point, namely, that the superiority of love over hatred is even greater. Nonetheless, over the last year or so, and particularly in the last few months, this proverb lies at the heart of why I have become an (almost) vegetarian (technically, a semi-vegetarian or flexitarian).

Our planet produces an abundance of food, enough to feed over ten billion people, according to some estimates. Yet we are in the middle of a food crisis, with wheat prices more than doubling in the last twelve months and other grain prices not far behind, leading to riots and political unrest amongst many poorer nations. If we are growing so much (and last year broke all records for maximum production), where does the food go? Increasingly, much of it is turned into biofuels so that first-world drivers (and governments) can feel less guilty about our energy-intense lifestyles. The corn used to generate one large petrol tank of ethanol-based fuel would feed a person for a year. Nonetheless, biofuels, although growing rapidly, still take only about 5% of the world's grain production.

So why are we short of food? One major reason is because we eat so much meat. To produce one kilogram of beef, it takes around eight kilograms of grain.* Chickens have a better ratio, but whatever your fancy, it still takes more energy to produce meat than other kinds of food. This article summarises a number of the key statistics and links them to current food prices (H/T Nicole), as does this one and this one and this one. The bottom line is that the western meat-based diet (and its increasing emulation by China and India) is helping push those on the edge of poverty into malnutrition. There is indeed plenty to go around, but our opulent lifestyle consumes so much that others cannot afford even the basics.
*This is also an issue of water management. To produce a kilo of wheat takes between 1-2,000 litres of water; a kilo of beef takes between 10,000-13,000 litres.

So can we, out of love for our neighbour, reduce our consumption of meat? I think it both possible and desirable, and now try to avoid buying or consuming it wherever possible. This is not to say that eating meat per se is wrong (though certainly there is much mistreatment of animals in our current system - another genuine moral issue, though a discussion for another time). On the contrary, I give thanks for meat as a good gift of God, but I am trying to regard it as an occasional luxury rather than a staple. There used to be a slogan "Live simply so that others can simply live"; I think we can also say "Eat simply so that others can simply eat". Better a meal of vegetables for everyone than a fattened calf for some while others go hungry.

PS This article puts some of the concerns well.

PPS I note there is also a Wikipedia article summarising some of the concerns.
