Gloom and Doom

I hate to be all gloomy and stuff, but the BBC, not typically known as a doomer web site, paints a vivid portrait of a post-antibiotic era in this analysis:
A terrible future could be on the horizon, a future which rips one of the greatest tools of medicine out of the hands of doctors. A simple cut to your finger could leave you fighting for your life. Luck will play a bigger role in your future than any doctor could. The most basic operations - getting an appendix removed or a hip replacement - could become deadly. Cancer treatments and organ transplants could kill you. Childbirth could once again become a deadly moment in a woman's life.

It's a future without antibiotics.

This might read like the plot of science fiction novel - but there is genuine fear that the world is heading into a post-antibiotic era. The World Health Organization has warned that "many common infections will no longer have a cure and, once again, could kill unabated". The US Centers of Disease Control has pointed to the emergence of "nightmare bacteria". And the chief medical officer for England Prof Dame Sally Davies has evoked parallels with the "apocalypse".

Antibiotics kill bacteria, but the bugs are incredibly wily foes. Once you start treating them with a new drug, they find ways of surviving. New drugs are needed, which they then find ways to survive. As long as new drugs keep coming, resistance is not a problem. But there has not been a new class of antibiotics discovered since the 1980s.

This is now a war, and one we are in severe danger of losing.

Antibiotics are more widely used than you might think and a world without antibiotics would be far more dangerous. They made deadly infections such as tuberculosis treatable, but their role in healthcare is far wider than that.Surgery that involves cutting open the body poses massive risks of infection. Courses of antibiotics before and after surgery have enabled doctors to perform operations that would have been deadly before. Cancer treatments such as chemotherapy and radiotherapy can damage the immune system. A course of antibiotics is prescribed to provide a much-needed boost alongside your body's own defences.Anyone with an organ transplant faces a lifetime of drugs to suppress the immune system, otherwise it attacks the transplant, so antibiotics are used to protect the body.

"It's a pretty grim future, I think a lot of major surgery would be seriously threatened," said Prof Richard James from the University of Nottingham. "I used to show students pictures of people being treated for tuberculosis in London - it was just a row of beds outside a hospital, you lived or you died - the only treatment was fresh air." And this, he says, is what running out of drugs for tuberculosis would look like in the future.

But this is all in the future isn't it?

"My lab is seeing an increasing number of resistant strains year on year," said Prof Neil Woodford, from the Health Protection Agency's antimicrobial resistance unit.
Analysis: antibiotic apocalypse

And even with all the talk of climate change, a new article in the journal Science is getting some major attention and discussion. As this chart shows, the earth is already on a heading to become warmer than it has been in the last 11,300 years, or essentially the entire lifetime of modern civilization:

Here's Stuart Staniford on what it means:
They combined 73 proxy records of temperature from around the globe - mainly from marine sediments - and used a Monte Carlo analysis to estimate the uncertainties. The result is the above picture of the entire Holocene - the period in which agriculture and civilization have arisen on this planet for the first time - together with the spike of the Anthropocene on the right - the period of major human impact on the climate.



Lloyd Alter, in a brilliant turn of analogy, notes that it resembles less a hockey stick and more a scythe - the traditional symbol of both traditional agriculture and the grim reaper. Symbolism, anyone?


P.S. If that's not enough doom for ya: Chances for slowing climate change fading fast (Treehugger). Kinda makes "the sequester" seem like small potatoes.

  1. Oh well: maybe the radiation from Fukushima will sterilize the bacteria .

    So, at worst, we'll be where we were before the antibiotic revolution. My father was born in 1921, and the first 20 years of his life without access to such drugs. My uncle did, too - but my uncle would be dead by now without these drugs, from a recurring infection.

    Regardless, I doubt the antibiotic resistance issue will be a main purveyor of death, compared to war and famine.

    Regarding Fukushima (happy anniversary, everyone!), there's no chance that the Japanese will be able to clean this up before they lose the ability to pay for the cleanup, or create the technology necessary to do so.

    1. Inside Fukushima's abandoned towns, two years on – in pictures: http://www.guardian.co.uk/environment/gallery/2013/mar/11/fukushima-abandoned-towns-in-pictures

      I've also seen pictures of hurricane Sandy's neighborhoods that are still abandoned. And then, of course, there's New Orleans. And I don't know how much the Gulf has recovered from Deepwater Horizon. This is neglected in the media - the places that are the victims of catastrophes are not being rebuilt
