Research on Beavers reintroduced into Poland’s forests suggests that their logging and dams help bats find insects:
We aimed to test the hypothesis that beaver activity promotes new foraging sites for insectivorous bats. The beaver’s influence can be especially significant on aerial hawkers that prefer moderate structural clutter, like the Pipistrellus species (by creating new canopy gaps), and on water-surface foragers, like Myotis daubentonii (by creating ponds with smooth water surface). The study was conducted on small streams in forest areas of northern Poland, which were colonized by the European beaver (Castor fiber). Bat activity was recorded with a Pettersson D-980 ultrasound detector on line transects. The number of bat passes was significantly higher in the stream sections modified by beavers (flooded and subjected to intensive tree cutting) than in the unmodified sections (for Pipistrellus nathusii, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Nyctalus noctula, and all species lumped together).
We suggest that mortality of bats at wind turbines may be linked to high-altitude feeding on migrating insects that accumulate at the turbine towers. Modern wind turbines seem to reach high enough into the airspace to interfere with the migratory movements of insects. The hypothesis is consistent with recent observations of bats at wind turbines. It is supported by the observation that mortality of bats at wind turbines is highly seasonal (August–September) and typically peaks during nights with weather conditions known to trigger large-scale migratory movements of insects (and songbirds).
A short film titled “SAC Command Post” from 1963 has been posted by the National Archives, which tries to play down any possibility of unauthorized U.S. nuclear strikes:
U.S. Air Force Special Film Project 1236, “SAC Command Post,” n.d, Produced by Air Force Audio Visual Service (Military Airlift Command), 1365th Photo Squadron
To refute early 1960s novels and Hollywood films like Fail-Safe and Dr. Strangelove which raised questions about U.S. control over nuclear weapons, the Air Force produced a documentary film–“SAC [Strategic Air Command] Command Post”–to demonstrate its responsiveness to presidential command and its tight control over nuclear weapons.
Watch and learn how power to preserve order is the “only way to world peace”:
…in a world where fragments of information come from so many sources, it often leads them to the odd place where any explanation of the world is as good as any other, where there is no conceptual rudder for judging one theory or idea against another. […] Hence, the tendency toward apathy and (after a philosophy class or two) nihilism.
Striffler seems to conclude that discussions about risk should still look at the role of political views and rhetoric, including confused and reactionary ones like Loughner’s.
It is a bit ironic that at the same time as many commentators are urging us to listen more closely to our opponents’ ideas and resist the urge to demonize them, that we are dismissing Loughner’s political views without even so much as a real discussion. What he did is horrible, but the commentary has gone too quickly from “Loughner’s actions were politically motivated” to “it had nothing to do with politics.”
In fact, there is no balance—none whatsoever. Only one side has made the rhetoric of armed revolt against an oppressive tyranny the guiding spirit of its grassroots movement and its midterm campaign. Only one side routinely invokes the Second Amendment as a form of swagger and intimidation, not-so-coyly conflating rights with threats. Only one side’s activists bring guns to democratic political gatherings. Only one side has a popular national TV host who uses his platform to indoctrinate viewers in the conviction that the President is an alien, totalitarian menace to the country. Only one side fills the AM waves with rage and incendiary falsehoods. Only one side has an iconic leader, with a devoted grassroots following, who can’t stop using violent imagery and dividing her countrymen into us and them, real and fake. Any sentient American knows which side that is; to argue otherwise is disingenuous.
