Showtime’s Global Warming Series Ignores the Biggest Way We’re ‘Living Dangerously’


In many ways, I’m very impressed by what Showtime has done with its in-depth series about climate change and the politics around it. Years of Living Dangerously is very straightforward and unapologetic, and it takes on the various types of folks who disbelieve in anthropogenic climate change without belittling them or their interests. I hope people are watching it, and I hope it is changing minds.

But I couldn’t help noticing that, for all the various investigative segments on a range of topics from the impact of lobbyists to various scientific concepts and back to the mindsets of doubters, one major subject seems to be actively avoided, not just overlooked. How is it possible that a series of such scope and depth could highlight the interests of cattle ranchers on two occasions without so much as noting their massive contribution to greenhouse gases clogging up our atmosphere and ironically harming their industry?


There can be no denying that animal agriculture is the largest single contributor to anthropogenic global warming. Full stop. Because it involves tremendous amounts of energy (which the meat industry simply discounts in its own propaganda), and because its waste products give off dangerous amounts of extremely hazardous methane and nitrous oxide, and because deforestation is a huge and growing factor, the biggest single reason we need a series like Years of Living Dangerously is animal agriculture. That is, our process of raising, slaughtering, and consuming animals on a mass scale is the number one way in which we’ve lived dangerously these last generations.

So how is it that Showtime can highlight the plight of cattle ranchers and meatpacking workers affected by droughts, only to lament that their means of livelihood are at risk, never pointing out how dangerous their businesses are to themselves and the rest of us? The show also notes that deforestation is a major contributor to global warming but fails to explain the number one cause of tropical deforestation is cropland for livestock feed. These ironies are too elegant to not highlight it at least in passing, yet they’re ignored in favor of presenting an innocently idyllic industry at risk due to sinister outside forces.

While I’d argue that the staggering contribution to global warming of the meat and dairy industries deserves its own episode, I must say it’s criminally negligent for this type of program to portray the plight of that dangerous industry without so much as noting its role in the problem. Unless I missed something, the number one way we can all actually do something about global warming is simply not mentioned in the entire series.


Because the Problem with the Combustion Engine is Who’s Driving


Market forces take us in pretty peculiar directions. The technophile in me says this is way cool, but the environmentalist wishes the geniuses making robot cars were working on something else, like mass transit.

There is one potential environmental advantage to driverless automobiles:

‘This kind of car is actually perfect for car sharing,’ said [Raul] Rojas [the head of the university’s research group for artificial intelligence]. ‘There will be no more need for owning a car — once the automobile has dropped off its passenger it will drive on to the next passenger.’

The idea of having fewer cars on the road sounds great for a few reasons. First, it implies less congestion. Also, fewer cars implies less oil consumption and lower emissions — indeed, fewer resources overall (metals, batteries, etc). But the number of cars on the road isn’t the only factor when it comes to carbon consumption and emissions.

The real variable, all else being equal, is the time (vehicle hours) spent actually driving on the roads. So fewer cars getting used way more often isn’t necessarily a net gain in this respect.

In fact, what if the market strongly encouraged increased use of personal vehicles among people who otherwise would rely on public transportation? If owning a share of a vehicle or multi-vehicle cooperative meant a car was delivered to you on schedule regularly and took you to your destinations for a couple of thousand dollars a year plus mileage fees, might you think twice about packing into a crowded subway platform day after day?

My point isn’t to suggest there aren’t smart solutions, or that the worst is inevitable even if the market was left to its devices, but I think leaving outcomes up to the market could be tragic. A little urban planning could go a long way toward keeping driverless autos on the right track, or mitigating the demand for them altogether by making mass transit cheaper and more attractive than it is today.

As an aside, this was one of my favorite bits from the article:

‘However, all in all, one can definitely say that computer-controlled cars will be much safer than human drivers,’ said [Ferdinand] Dudenhoeffer, a professor for automotive economics. ‘Especially if you keep in mind that most of today’s accidents are caused by human error.’

An economist who peddles bizarre logical fallacies? Hard to believe, right? So the fact that human error causes most accidents in a world where there is literally just one robot car on the road (for just a few months) is evidence that robot cars will be safer when there are more of them on the road. I mean, right now the robot error rate is zero! This guy is a professor.
