After experiments on the Eastern Front, the German Army is using poison gas for the first time on the Western Front. At the beginning of the 2nd Battle of Ypres, the wind blows in a favourable direction; the wide spread use of chlorine gas has a devastating effect on the French troops. Even the Germans are surprised by it. The incredible sacrifice of the Canadian troops make it possible to defend Hill 60 in the end.

Framing every conservation issue in terms of “extinction” is counter-productive
Stewart Brand wants us to stop presenting so many conservation concerns in the headline-grabbing “Fluffy Bunnies At Risk!” format:
The way the public hears about conservation issues is nearly always in the mode of ‘[Beloved Animal] Threatened With Extinction’. That makes for electrifying headlines, but it misdirects concern. The loss of whole species is not the leading problem in conservation. The leading problem is the decline in wild animal populations, sometimes to a radical degree, often diminishing the health of whole ecosystems.
Viewing every conservation issue through the lens of extinction threat is simplistic and usually irrelevant. Worse, it introduces an emotional charge that makes the problem seem cosmic and overwhelming rather than local and solvable. It’s as if the entire field of human medicine were treated solely as a matter of death prevention. Every session with a doctor would begin: ‘Well, you’re dying. Let’s see if we can do anything to slow that down a little.’
Medicine is about health. So is conservation. And as with medicine, the trends for conservation in this century are looking bright. We are re-enriching some ecosystems we once depleted and slowing the depletion of others. Before I explain how we are doing that, let me spell out how exaggerated the focus on extinction has become and how it distorts the public perception of conservation.
Many now assume that we are in the midst of a human-caused ‘Sixth Mass Extinction’ to rival the one that killed off the dinosaurs 66 million years ago. But we’re not. The five historic mass extinctions eliminated 70 per cent or more of all species in a relatively short time. That is not going on now. ‘If all currently threatened species were to go extinct in a few centuries and that rate continued,’ began a recent Nature magazine introduction to a survey of wildlife losses, ‘the sixth mass extinction could come in a couple of centuries or a few millennia.’
The fossil record shows that biodiversity in the world has been increasing dramatically for 200 million years and is likely to continue. The two mass extinctions in that period (at 201 million and 66 million years ago) slowed the trend only temporarily. Genera are the next taxonomic level up from species and are easier to detect in fossils. The Phanerozoic is the 540-million-year period in which animal life has proliferated.

The range of dates in that statement reflects profound uncertainty about the current rate of extinction. Estimates vary a hundred-fold – from 0.01 per cent to 1 per cent of species being lost per decade. The phrase ‘all currently threatened species’ comes from the indispensable IUCN (International Union for Conservation of Nature), which maintains the Red List of endangered species. Its most recent report shows that of the 1.5 million identified species, and 76,199 studied by IUCN scientists, some 23,214 are deemed threatened with extinction. So, if all of those went extinct in the next few centuries, and the rate of extinction that killed them kept right on for hundreds or thousands of years more, then we might be at the beginning of a human-caused Sixth Mass Extinction.

Relative and absolute poverty
We in the west are so rich, in historical terms, that we are losing our grasp on what poverty really has been for the majority of humankind for the majority of our recorded history:
People generally just don’t get what poverty actually means. This is a charge often enough aimed at me and people like me, well off white guys who pontificate upon economics. But those making that charge often enough don’t actually understand what real poverty means. So, here’s a nice example of it. There’s a campaign in New York to insist that SNAP (ie, food stamps) should not be cut. Views on that can vary either way: I’m generally in favour of a larger welfare state than the one the US has at present so I’m probably against such a cut. But that’s a political point and not the one I’m interested in here. Rather, I want to point out just quite how rich someone getting food stamps is on any global or historical basis.
Yes, you did read that right: how rich someone getting food stamps is. As one example, the food stamp allocation in New York State appears to be $29 per person per week in a family receiving the full possible allocation. That, on its own, is a yearly income of $1,508 and that’s an amount that puts you, on its own, in the top 50% of all income recipients in the world. No, really, you can look that up with this little calculator. More than half of humanity is poorer than someone who only gets the New York food stamp allocation.
All of which gives us an interesting little look into the difference between absolute poverty and relative poverty. For, obviously, the people who are receiving food stamps in New York are those we consider to be poor in our own society. And in our own society, they are indeed poor, as Adam Smith pointed out with his linen shirt example. It’s not necessary for a working man to have a linen shirt, he’s not poor because he cannot afford one. But if you live in a society where you are considered to be poor if you cannot afford a linen shirt, and you cannot afford one, then in that society you are of course poor. This is relative poverty, more usefully known not as a measure of poverty but of inequality.

Gavin McInnes on the polygraph machines and their questionable accuracy:
I met Doug Williams in August while developing a pilot for a TV show about myth busting. He’s the most vocal critic of polygraph machines in the world and authored the book From Cop to Crusader: My Fight Against the Dangerous Myth of “Lie Detection.” Williams’ history in law enforcement brought him from the Oklahoma City Police Department to the White House where he served under Johnson and Nixon as a communications advisor (Johnson was cool, Nixon was a dick). He has issued thousands of polygraph tests over the years and even helped make the test part of federal law.
Doug started to realize the whole thing was a scam in the late 1970s and since then has devoted his entire life to giving everyone else the same epiphany. Unfortunately, the government doesn’t see it the same way and on May 12th, his trial will begin for the crime of “train[ing]… customers how to conceal misconduct and other disqualifying information.” He was busted by two undercover federal agents who took his course and decided the class had gone from simply “debunking” to “aiding and abetting.” The Feds are trying to say that Williams is hampering investigations, but all he’s doing is proving these machines don’t work by presenting evidence. 60 Minutes did the same thing in a 1986 episode where three out of three experts failed their own test. People are losing their jobs and going to prison based on the findings of a machine that appears to be totally unreliable. The only thing he’s hampering here is the abuse of power. The irony is, if it’s possible to beat a polygraph, it clearly isn’t a reliable piece of equipment. If it’s not possible to beat, his courses are irrelevant. You can teach someone to trick a police radar all you want. It’s still going to clock you if you’re going over the speed limit. This seems like common sense yet the state has won cases like this before. In 2013, an electrician named Chad Dixon was sentenced to 8 months in jail for helping people beat the machine.
