World Council of Churches Statement on Eco-Justice and Ecological Debt

Many of us attempt to bring ethical perspectives to bear on issues raised by our classes in addition to ecological and economic perspectives.  Although it may be a bit late for those of you who have already started class, here is the most recent statement by the World Council of Churches on eco-justice and ecological debt.  In a related, but fascinating, note, the WCC as part of its current  programme work on poverty, wealth and ecology is attempting to articulate a consumption and greed line -- in addition to the more typical poverty line.  This would provide practical spiritual guidance on when, in Christian terms, too much is too much.  Check it out!!!


WCC Statement on eco-justice and ecological debt

02.09.09

The World Council of Churches (WCC) Central Committee adopted a "Statement on eco-justice and ecological debt" on Wednesday, 2 Sept. The statement proposes that Christians have a deep moral obligation to promote ecological justice by addressing our debts to peoples most affected by ecological destruction and to the earth itself. The statement addresses ecological debt and includes hard economic calculations as well as biblical, spiritual, cultural and social dimensions of indebtedness.

 The statement identifies the current unprecedented ecological crises as being created by humans, caused especially by the agro-industrial-economic complex and the culture of the North, characterized by the consumerist lifestyle and the view of development as commensurate with exploitation of the earth's so-called "natural resources". Churches are being called upon to oppose with their prophetic voices such labeling of the holy creation as mere "natural resources".

 The statement points out that it is a debt owed primarily by industrialized countries in the North to countries of the South on account of historical and current resource-plundering, environmental degradation and the dumping of greenhouse gases and toxic wastes.

In its call for action the statement urges WCC member churches to intervene with their governments to drastically reduce greenhouse gas emissions and to adopt a fair and binding deal at the UN climate conference in Copenhagen in December 2009, in order to bring the CO2 levels down to less than 350 parts per million (ppm).

 Additionally the statement calls upon the international community to ensure the transfer of financial resources to countries of the south to refrain from oil drilling in fragile environments. Further on, the statement demands the cancellation of the illegitimate financial debts of the southern countries, especially for the poorest nations as part of social and ecological compensation.

In a 31 August hearing on "ecological debt" during the WCC Central Committee meeting in Geneva, Dr Maria Sumire Conde from the Quechua community of Peru shared some ways that the global South has been victimized by greed und unfair use of its resources. In the case of Peru, Sumire said mining has had particularly devastating effects, such as relocation, illness, polluted water,and decreasing biodiversity.

 The concept of ecological debt has been shaped to measure the real cost that policies of expansion and globalization have had on developing nations, a debt that some say industrialized nations should repay. Dr Joan Martinez Alier, a professor at the Universidad Autònoma de Barcelona in Spain, said climate change, unequal trade, "bio-piracy", exports of toxic waste and other factors have added to the imbalance, which he called "a kind of war against people around the world, a kind of aggression."

 Martinez went on saying: "I know these are strong words, but this is true." He beseeched those present, at the very least not to increase the existing ecological debt any further.

 The WCC president from Latin America, Rev. Dr Ofelia Ortega of Cuba, said ecological debt was a spiritual issue, not just a moral one. "The Bible is an ecological treatise" from beginning to end, Ortega said. She described care for creation as an "axis" that runs through the word of God. "Our pastoral work in our churches must be radically ecological," she said.

How this virus developed and why it may be a killer

The Mexican swine flu virus is a swine influenza A/H1N1 virus hybridized (mixed) with human and bird viruses.  We have some immunity to human flu and to some strains of swine influenza A/H1N1;  We don't have immunity to bird flu, which is why that virus is so virulent - with a kill ratio of almost 50% -- and why so much pandemic planning and preparedness focused on bird flu.

New Scientist reports:

This type of virus emerged in the US in 1998 and has since become endemic on hog farms across North America. Equipped with a suite of pig, bird and human genes, it was also evolving rapidly.  Flu infects many animals, including waterfowl, pigs and humans. Birds and people rarely catch flu viruses adapted to another host, but they can pass flu to pigs, which also have their own strains.If a pig catches two kinds of flu at once it can act as a mixing vessel, and hybrids can emerge with genes from both viruses. This is what happened in the US in 1998. Until then, American pigs had regular winter flu, much like people, caused by a mutated virus from the great human pandemic of 1918, which killed pigs as well as at least 50 million people worldwide. This virus was a member of the H1N1 family - with H and N being the virus's surface proteins haemagglutinin and neuraminidase.  Over decades, H1N1 evolved in pigs into a mild, purely swine flu, and became genetically fairly stable. In 1976, there was an outbreak of swine H1N1 in people at a military camp [Fort Dix] in New Jersey, with one death. The virus did not spread efficiently, though, and soon fizzled out.

But in 1998, says Richard Webby of St Jude's Children's Research Hospital in Memphis, Tennessee, swine H1N1 hybridised with human and bird viruses, resulting in "triple reassortants" that surfaced in Minnesota, Iowa and Texas. The viruses initially had human surface proteins and swine internal proteins, with the exception of three genes that make RNA polymerase, the crucial enzyme the virus uses to replicate in its host. Two were from bird flu and one from human flu. Researchers believe that the bird polymerase allows the virus to replicate faster than those with the human or swine versions, making it more virulent.

By 1999, these viruses comprised the dominant flu strain in North American pigs and, unlike the swine virus they replaced, they were actively evolving. There are many versions with different pig or human surface proteins, including one, like the Mexican flu spreading now, with H1 and N1 from the original swine virus. All these viruses still contained the same "cassette" of internal genes, including the avian and human polymerase genes, reports Amy Vincent of the US Department of Agriculture (USDA) in Ames, Iowa (Advances in Virus Research, vol 72, p 127). "They are why the swine versions of this virus easily outcompete those that don't have them," says Webby.

But the viruses have been actively switching surface proteins to evade the pigs' immunity. There are now so many kinds of pig flu that it is no longer seasonal. One in five US pig producers actually makes their own vaccines, says Vincent, as the vaccine industry cannot keep up with the changes. This rapid evolution posed the "potential for pandemic influenza emergence in North America", Vincent said last year. Webby, too, warned in 2004 that pigs in the US are "an increasingly important reservoir of viruses with human pandemic potential". One in five US pig workers has been found to have antibodies to swine flu, showing they have been infected, but most people have no immunity to these viruses.

The virus's rapid evolution created the potential for a pandemic to emerge in North America.  Our immune response to flu, which makes the difference between mild and potentially lethal disease, is mainly to the H surface protein. The Mexican virus carries the swine version, so the antibodies we carry to human H1N1 viruses will not recognise it. That's why the CDC warned last year that swine H1N1 would "represent a pandemic threat" if it started circulating in humans. The avian polymerase genes are especially worrying, as similar genes are what make H5N1 bird flu lethal in mammals and what made the 1918 human pandemic virus so lethal in people. "We can't yet tell what impact they will have on pathogenicity in humans," says Webby. It appears the threat has now resulted in the Mexican flu. "The triple reassortant in pigs seems to be the precursor," Robert Webster, also at St Jude's, told New Scientist.

While researchers focused on livestock problems could see the threat developing, it is not one that medical researchers focused on human flu viruses seemed to have been aware of. "It was confusing when we looked up the gene sequences in the database," says Wendy Barclay of Imperial College London, who has been studying swine flu from the recent US cases. "The polymerase gene sequences are bird and human, yet they were reported in viruses from pigs."

So where did the Mexican virus originate? The Veratect Corporation based in Kirkland, Washington, monitors world press and government reports to provide early disease warnings for clients, including the CDC. Their first inkling of the disease was a 2 April report of a surge in respiratory disease in a town called La Gloria, east of Mexico City, which resulted in the deaths of three young children. Only on 16 April - after Easter week, when millions of Mexicans travel to visit relatives - reports surfaced elsewhere in the country.

Local reports in La Gloria blamed pig farms in nearby Perote owned by Granjas Carroll, a subsidiary of US hog giant Smithfield Foods. The farms produce nearly a million pigs a year. Smithfield Foods, in a statement, insists there are "no clinical signs or symptoms" of swine flu in its pigs or workers in Mexico. That is unsurprising, as the company says it "routinely administers influenza virus vaccination to swine herds and conducts monthly tests for the presence of swine influenza." The company would not tell New Scientist any more about recent tests. USDA researchers say that while vaccination keeps pigs from getting sick, it does not block infection or shedding of the virus.

All the evidence suggests that swine flu was a disaster waiting to happen. But it got little research attention, perhaps because it caused mild infections in people which didn't spread. Now one swine flu virus has stopped being so well-behaved.

This leads us to the policy question: why should humans keep pigs?  Like other meat, pigs consume an extraordinary amount of resources to provide nutrition.  Maybe the ancient Israelites had an insight that we have lacked -- there may be more wisdom in the Torah and its laws than we knew.  Perhaps it is time, or past time, for our eating habits to evolve lest an even more virulent strain of swine flu develop.  Assuming that this pandemic passes without too many deaths, we may need to rethink whether it is good to keep large quantities of pigs.  For now, the virulent bird flu does not seem easily communicable.  Let's keep it that way.
