Taking a short break - no post this week

I am taking a short break this week and plan to post again on Sunday, July 7.

What the H5N1 scare tells us about ourselves and our society

I don't know whether there is an H5N1 "bird flu" pandemic in our future. H5N1 seems to be very dangerous to humans. Half of the 900 people known to have contracted it worldwide since 2003 have died. And, so a lot of scientists are concerned about the possibility of a pandemic now that the virus has crossed over into mammals including dairy cows.

That means that the milk we drink may have the virus in it though the U.S. Food and Drug Administration says that pasteurization makes the milk safe. Or does it? A recent study indicates that a "small but detectable quantity" of H5N1 bird flu virus can survive "a common approach to pasteurizing milk."

We humans think we can build moats around our modern way of life that protect us from the natural world. We will pasteurize our milk and that will solve the problem. We will spray kitchen counters with some noxious disinfectant to kill offending organisms. We will wash our hands again and again with anti-bacterial soaps. And, when soap and water are not available, we'll use hand sanitizer. All the while we have actually been building the equivalent of superhighways into the heart of human society everywhere due to our dense living arrangements and global travel and trade.

Boondoggle Watch: Carbon capture great for making things worse, study finds

The study I refer to didn't actually say that carbon capture makes things worse. But that is the only conclusion one can draw given that the capturing is done for the purpose of dramatically lengthening the life of oil wells that would otherwise close, according to a recent piece in DeSmog. The oil wells in question are in Saskatchewan and were scheduled to close in 2016. Now with carbon dioxide pumping into them, they could produce oil for somewhere between 39 and 84 more years.

Back in May I reminded readers of a more expansive definition of the word "boondoggle," one promulgated by author Dmitri Orlov. To wit: It's not just something that is wasteful. Ideally, it should be something which "create[s] additional problems that can only be addressed by yet more boondoggles."

Carbon capture, it turns out, provides an excellent complementary boondoggle to the machines mentioned in my previous piece, machines which extract carbon dioxide from air rather than at the source as is done with carbon capture. In this case the carbon dioxide comes from the Dakota Gasfication Plant in Beulah, North Dakota, which according to its website is "the only commercial-scale coal gasification facility in the United States that manufactures natural gas." The gas—made synthetically from lignite coal—is piped to various electric cooperatives in five states which burn it to generate electricity. The captured carbon dioxide is then transmitted via pipeline to the Weyburn and Midale oil fields in Saskatchewan and injected into oil wells to force oil out, something the industry refers to as enhanced oil recovery.

After Cape Town will a breakdown of confidence bring 'Day Zero' to Mexico City and Bogotá?

'Day Zero' never arrived in Cape Town, South Africa. Day Zero was the name given by Cape Town officials to the day in 2018 they would have to shut down water flows to most of the city taps because of inadequate water supplies—supplies that had run desperately short in the wake of an extreme three-year drought. Day Zero never came for two reasons: First, those officials cajoled Cape Town residents into cutting water consumption in half. Second, the rains finally resumed a few months later.

Now Mexico City and Bogotá are both facing their own possible Day Zero. Droughts, aging infrastructure, poor water management and climate change have resulted in dangerously low water supplies. But, as this piece in Grist points out, it may not be so easy to convince residents of the two cities that the problem is real and that they should trust the pronouncements of their city officials.

The city administration in Cape Town generally enjoys the trust of its citizens who rallied together with widespread voluntary efforts to reduce water consumption. Neither Mexico City nor Bogotá enjoy that same kind of credibility.

Residents of both cities may simply keep their fingers crossed and hope for rain. And, if they do and the rain doesn't come, then Day Zero will arrive.

Messy business: Polluted 'biosolids' derail recycling of human waste

Many years ago a civil engineer explained to me the wisdom of taking solid biological residues from sewage treatment plants—dubbed biosolids—and using them on farm fields and garden plots. After all, nature intended for human wastes to return to the soil to replenish it in the same way animal manure has long been used to fertilize farm fields.

"What about all the industrial chemicals that end up in wastewater," I asked. He replied that these weren't significant enough to be concerned. I was skeptical.

Fast forward to last week when the U.S. Congress took up a proposal to allocate $500 million to compensate farmers whose livelihoods have been undermined by applying biosolids—what most of us call sewage sludge—to their cropland. It turns out that those biosolids have poisoned both land and livestock across the United States. The ostensible concern is so-called "forever chemicals," ones used to make such products as Teflon, firefighting foam, stain-resistant upholstery and water-resistant sports gear. These chemicals are linked to "cancer, liver damage, decreased fertility, and increased risk of asthma and thyroid disease." They are dangerous to human and animal health even at very low levels. The U.S. Environmental Protection Agency (EPA) this year proposed limiting certain of these chemicals to less than 10 parts per trillion in drinking water. In two cases, the proposed limit is 4 parts per trillion.
