Ecological responsibility and Christian discipleship I: Human planet

This will be the first in three posts giving a slightly modified version of a sermon I delivered a few weeks ago based on Genesis 1. The three posts are as follows:
I. Human planet: Welcome to the Anthropocene.
II. The Community of Creation: Genesis 1.
III. Recycle or repent? Our response.

Human Planet: Welcome to the Anthropocene
We no longer live on the same planet on which we were born. I’m not just talking about the internet and globalisation, or trends in fashion and music. The chemistry of the oceans and atmosphere, the stability of the climate, the diversity and health of ecosystems are all very different to what they were. Human activity over the last handful of decades has altered the face of the globe in ways so profound that it will be visible in the geological record millions of years into the future. The Geological Society of London, which is the UK national society for geoscience and the oldest geological society in the world, is currently considering a serious proposal to declare that we have now left the Holocene and entered into a new geological epoch, called the Anthropocene, named after anthropos, which is Greek for human, because we humans are having such a extreme effect on all the ecosystems and even geology of the planet. I hardly need to tell you that most of it isn't a positive effect.

Think of the most remote places on the planet, places so wild and desolate that none live there. No matter where you picture, human fingerprints are all over the landscape.

You are probably aware that Arctic summer sea ice is in terminal decline and many of us in this room are likely to live to see a largely ice-free Arctic in summers to come. This winter, while we shivered through a December that was 5ºC below average, parts of the Canadian Arctic averaged 21ºC above their long term mean. Permafrost is no longer looking so permanent and some now call it "tempfrost". As it melts, not only are roads and buildings sinking and breaking, but it is releasing more and more of the methane and carbon dioxide that have been locked away for millennia and which will, of course, only make the melting worse.

If the Arctic isn't pristine, then perhaps the mountains, the high Andes and towering Himalayas? Well, again, you're probably aware of the accelerating glacier melt occurring on 95% of all glaciers, including the most remote. And in many places the melt is accelerated when soot particles land from cooking fires and factories land on the ice, darkening the surface and absorbing more solar energy. Indeed, thanks to Julian Assange, we know that the US State Department was told by the Dalai Lama that addressing climate change is a higher priority for Tibet than independence from China.

What about the deep Amazonian rainforest where there are still to this day dozens of uncontacted tribes? Yet first contact for these indigenous groups is most likely to be with loggers. Although deforestation rates have declined from a decade ago, tropical rainforests continue to be bulldozed at a rate of a football field every few seconds. Eighty percent of the world's ancient forests have been destroyed or degraded, half of that has been in the last 30 years.

What about bottom of the ocean? Even there the human fingerprints are everywhere. Deep sea trawling by commercial fishing fleets drags heavy metal beams over the sea floor, crushing and scattering slow-growing deep corals and other creatures and kicking up plumes of underwater dust that can be seen by satellites. And each year, an area twice the size of the continental United States is bottom trawled, scooping up more fish than the ocean can replenish. Four-fifths of commercial fish species are considered by marine biologists to be fully-exploited, over-exploited or have collapsed. On our current trajectory, no commercially-viable fish stocks will be left by the time my daughter turns 40.

Feeling stressed? Breathe in – breathe out – breathe in – breathe out. Every second breath comes from phytoplankton, microscopic plant-like organisms in the oceans that are the basis of the marine food chain and which are the source of over half the planet's oxygen. And yet, there is evidence that the number of phytoplankton has declined by 40% since 1950. I've already alluded to climate change, but did you know that all the excess carbon dioxide in the atmosphere is also changing the chemistry of the oceans? The planet's oceans are on average 30% more acidic than pre-industrial times, more acidic than they have been for millions of years and changing faster than any known previous shift. And they are getting warmer too. Climate change is first and foremost oceanic change, since oceans absorb more than 93% of the extra energy trapped by our greenhouse gas pollution. Oceanic currents are shifting. Sea levels are rising. The climate is warming: 2010 was the equal warmest year at the end of the warmest decade, which followed the previous warmest decade, which followed the previous warmest decade on record. The last 311 consecutive months have all been warmer than the 20thC average.

Seasons are changing. Plants flowering earlier in Spring, migrations and hibernations patterns are shifting. Our actions are shifting rainfall patterns: stronger droughts, more intense rain and snow.

Human actions are responsible for the extinction of about a thousand recorded species. They are just the ones we're aware of. Our best estimates of how many we've actually bumped off falls between twenty thousand and two million. And this is rising rapidly, causing most biologists to judge that we are currently causing the start of the sixth great extinction event in earth's four and a half billion year history.

Since 1970 we have reduced animal populations by 30%, the area of mangroves and sea grasses by 20%, the coverage of living corals by 40% and large African mammals by more than 60%.

Over 60% of major rivers in the world are dammed or diverted. There is five times as much water stored in dams and reservoirs as all the world's rivers put together. We have directly modified three quarters of the ice-free land surface of the planet and currently move more soil each year than the natural cycles of wind and water.

And I haven’t mentioned heavy metal toxins, soil degradation, aquifer depletion, ocean eutrophification, introduced species, desertification, or the trillions of floating plastic particles found in all the world's oceans.

We no longer live on the same planet on which we were born.

And God said to them, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea. And over the birds of the air and over every living thing that moves upon the earth."
- Genesis 1.28 (NRSV).
Our passage this morning has been used to justify the patterns of exploitation and acquisition that in our lifetimes have reached such an extent as to have permanently altered the face of the planet. Can we read it again with fresh eyes and see whether it might have good news for us today?
I haven't had time to include links for all these claims, though it's worth noting that they were not first published by Greenpeace or WWF; they are not the scare stories of eco-extremists out to rob you of your fun or set up a world government. These claims appear in highly respected scientific journals – Nature, Science, Proceedings of the Royal Society and so on. Some are still quite fresh and subject to ongoing debate. Most are widely agreed as our best knowledge of our present situation. If there are particular ones you are interested in, I can try to provide relevant citations.

Insert head (A) into sand (B)

CP: Amazonian drought, another climate wildcard. This is a lengthy post, but worth a read for its significance.

BBC: Mining tax should be higher says OECD.

TPM: Insert head (A) into sand (B).

Running out of places to fish.

Alaskan wildfires getting more intense, and now Alaskan forests and soils are releasing more carbon than they are storing.

The places where fish choke.

Hot Topic: The rainforests of the sea are burning.

Mongabay: Climate change likely to kill five million annually by 2020, mainly children.

I support WikiLeaks*

"Publishing improves transparency, and this transparency creates a better society for all people. Better scrutiny leads to reduced corruption and stronger democracies in all society's institutions, including government, corporations and other organisations. A healthy, vibrant and inquisitive journalistic media plays a vital role in achieving these goals. We are part of that media."

- WikiLeaks.

Of course, if you currently try to follow that link, you'll find that it gives an error message, thanks to the US government's ruthless harassment and attempts to ostracise WikiLeaks (ironically, a strategy that was outlined in a US Department of Defence document itself leaked by WikiLeaks earlier this year). You can also try here.

There is much to say about the role of WikiLeaks over the last four years. They have broken a wide variety of important information about corruption and abuses of corporate and state power. Not every leak has been equally useful or important, and sometimes perhaps more has been released than was necessary to hold the powerful to account, which may or may not be the case in the current controversy (though currently, only a small fraction of the total files have been released). Nonetheless, from what has already been released, the prima facie case for the release being in the public interest is strong. While we might not need to know internal US diplomatic gossip about which world leaders are liked or disliked (often not that much of a secret in any case), finding evidence that seems to indicate that the US government has been breaking treaties and encouraging other nations to break treaties is no small matter, nor are revelations of the UK Parliament apparently being misled by the Foreign Office.

Yet the most common reaction to these revelations follows the lead of the government currently most damaged by them: distraction through counter-accusation. I am not aware of the legality under US or international law of what WikiLeaks have done (though Assange points out that WikiLeaks have been involved in over 100 legal attacks over the last four years and won them all), but I am aware of at least some of the illegalities exposed. The hunt for Julian Assange is a distraction, as is the witch hunt being put together to assassinate his character (or his person, if some are to be believed). This is what ought to be happening at the very least: resignations of those whose actions have been shameful.

Yet when Assange called on Clinton to resign for issuing instructions to diplomats that apparently break international treaties concerning the UN, the reaction from the White House was "I'm not entirely sure why we care about the opinion of one guy with one website". This response shifts the focus from the substance of what Clinton (and Rice before her, for that matter) has done and onto the journalists who broke the story, blaming the messenger. The question is not whether they care about one man and his website, but whether we all care about what government officials do in our name.

There seem to be plenty more stories yet to come out of the cables. The next major release due sometime in the new year is said to contain evidence of corruption and malpractice at a major US bank.
*The fine print is that I don't agree with everything that WikiLeaks has done, and think that Julian Assange can come across with characteristic Aussie bluntness (rudeness) at times, yet the role that WikiLeaks has already played and continue to play is a very important one. Democracy relies on accurate and relevant information available to those who participate in public deliberation. Where corporations or governments seek to hide information that is relevant to matters of public deliberation on the common good, then they ought to be held to account and whistleblowers deserve principled protection.

UPDATE: If you're having trouble getting to the WikiLeaks site, this site is keeping track of the hundreds of mirroring sites and you should be able to find access.

Sustainable development?

Here is a short cartoon booklet offering a satirical look at what "sustainable development" often means for indigenous peoples.
H/T Jeremy Kidwell.

Amongst the most vulnerable peoples in the world are the so-called "lost tribes". Did you know that there are still over one hundred tribes around the world who are largely isolated from the rest of the world, in fact who reject contact? For many of these "uncontacted peoples", their immune system has never faced disease or illness and even a common cold can be fatal. Most tribes at first contact experience horrific mortality rates (up to 100% in some cases) from such deadly viruses as the common cold or chickenpox. Many of these groups are not entirely uncontacted, but their experience of civilisation has been of disease, violence, slavery, exploitation and contempt. No wonder they choose to go it alone.

I came across this issue as the result of reading about this story, which presents an interesting ethical debate about the risks that are acceptable in expanding human knowledge. An update to this story can be read here.

UPDATE July 2011: After the failure of the natural history museum project, the real dangers to the ecology and uncontacted tribes of this area are becoming clearer.

Choking on coal

Washington Independent: coal related health effects cost the US $100 billion each year, including over 13,000 deaths. I imagine that even prior to considerations of climate change, if the public health effects of burning coal are taken into account, renewable energy is more affordable than such dirty combustion. Meanwhile, the head of BHP Billiton has said that Australia needs to move beyond coal. And finally, images of coal ash in China.

Independent: UK government to adapt to inevitable warming, yet without spending any more money.

Mongabay: Amazon.com vs the Amazon: paper trails and deforestation.

Deep-sea trawling damages an area twice the size of the contiguous USA each year.

And just to show that sometimes simultaneous disasters can dilute rather than amplify each other: Scientific American reports on research showing that hurricanes help save thermally-stressed coral reefs by cooling water temperatures; Skeptical Science points out that in New York, higher rainfall doesn't necessarily mean more flooding due to drier soil from higher temperatures; and NASA satellites reveal that the incidence of wildfires is no higher in dead forests killed by mountain pine beetle infestations (which have reached epidemic proportions due to warmer winters enabling more beetles to survive) since green needles of live trees are more flammable than brown needles of dead ones.

These points vaguely remind me of the story of a man who wanted to kill himself and so decided to do a thorough job. He hung himself over a lake after taking poison and brought along a gun to make sure. His shot missed his head and severed the noose, dropping him into the water which diluted the poison. Since all the other methods had failed, he decided he wanted to live after all and so swam to shore and survived. I'm not sure we're going to be so lucky.
