(PS. Why do you assume I would be shocked to hear something bad about canada, a country I've never visited?)
In any case, given that you cannot forbid farmers to act in stupid (short term profit-maximizing) fashion -- since it is nearly impossible to police them in most countries -- I much prefer a world in which different farmers are planting different crops than a world in which all farmers are encouraged (via Monsanto et. al propaganda) to plant the same crop.
For similar reasons, you cannot leave the decision to use/not use this "potentially useful tool" to individuals, because of Monsanto's aggressive blackmail practices.
As for your claim that insect die-off isn't caused by Roundup specifically, but some other herbicide: this may be, but monoculturation is a big reason why herbicides are becoming more important to use, making it undesirable that Monsanto (et al.) gain a (worldwide) oligopoly status as supplier of seeds. (This is also why your claim that 'this is also a problem with other cultivars' has only limited validity: before we saw this push towards monoculturation, herbicides played a far smaller role in food production.)
Lastly, here's a nice article that discusses how weeds are becoming multiply resistant in time-spans that were considered "theoretically" impossible.
Video footage has emerged of a police officer beating an Iraq war veteran so hard that he suffered a ruptured spleen in an apparently unprovoked incident at a recent Occupy protest in California.
The footage, which has been shared with the Guardian, shows Kayvan Sabehgi standing in front of a police line on the night of Occupy Oakland's general strike on 2 November, when he is set upon by an officer.
He does not appear to be posing any threat, nor does he attempt to resist, yet he is hit numerous times by an officer clad in riot gear who appears determined to beat him to the ground.
Sabehgi, 32, an Oakland resident and former marine who served in Iraq and Afghanistan, has since undergone surgery on his spleen. He says it took hours for him to be taken to hospital, despite complaining of severe pain. Police have told the Guardian they are investigating the incident.
The footage was recorded by artist and photographer Neil Rivas, who said Sabehgi was "completely peaceful" before he was beaten. "It was uncalled for," said Rivas. "There were no curse words. He was telling them he was a war vet, a resident of Oakland, a business owner."
Sabehgi has previously said he was talking to officers in a non-violent manner prior to his arrest, which the footage appears to confirm.
The 32-year-old can be seen standing in front of a line of police officers, all of whom are in riot gear. The officers walk forward, chanting and thrusting their batons, and Sabehgi starts to walk backwards.
Although the video is dark, an officer can clearly be seen beginning to hit Sabehgi around the legs with a baton, then starting to strike him higher up.
Secondly, please note that I have nothing against observational research. I have something against shoddily set up observational research, and I think that the latter is a rampant issue in the social (and that includes medical) sciences. Ioannidis, IIRC, also mentions somewhere how the more shocking the 'finding', the more likely it is to turn out a misinterpretation of data, or an outright statistical fluke (or worse). This is part of what I mean by "lack of replicability".
Lastly, I am not sure what you're trying to accomplish by straw-manning me, and suggesting I am a 'scientific bigot.' Again, I have already stated in the post you are replying to that I think that anything can be studied scientifically. Observational research is a fine, and a legitimate mode of research, depending on how it is done. What I object to is simply the -- pervasive -- attitude of not taking methodological issues seriously, and the equally wide-spread issues with the lack of statistics education. I can understand that understanding statistics is difficult, and that it is frustrating that the education system is lacking in that respect, but from this it does not follow that those issues can be ignored, or that knowing which button to press without understanding the limits of the tests being used is unproblematic..
Compare: when a physicist finds something shocking, he tries in pretty much any way he can to explain it, by doing new tests, etc. When a social scientist finds something exciting he is generally reluctant to go over the data again because he knows the statistics behind it are dubious at best, he will cite money constraints as preventing him from retesting his hypothesis in a different fashion, and he will quickly try to submit his Amazing Finding to Science. Now, while I will admit that I am now slightly type-casting, and probably over-hyping the physical scientist, it seems to me that this difference in basic attitude is quite important.
Certainly the subject can potentially be researched scientifically, but from that it does not follow that the actual research being done is actually rigorous.
