Comment Re:.3um (Score 2) 391

I agree smaller dose intuitively means less of a hazard of an infection putting down roots before the immune system wipes it out. However, I've never seen data for this.

IIRC coronavirus particles were around 0.1 um, but the virus would fall apart traveling bare. N95 do filter in that range in any event, just not at the advertised and tested level of an N95's 95% @ 0.3 um (you can get N100s which don't quite hit 100%; it's a rounding thing). Aerosols are typically much larger, 1+ um up, then transition to visible droplets around 20-100 um.

I'm afraid another pivotal concern may have been costs: inferior masks such as surgical are much cheaper. So, here in Virginia the hospital admin logic went, the mask they chose should be the standard for all purposes (our hospital required visitors to give up their personal N95s for a surgical mask, which was at least free).

As even more damning evidence of institutional thinking, the same hospital network required my PCP to wear a mask for telemedicine visits. I burst out laughing when I saw him and asked, "I don't mean to be rude, but are y'all familiar with the germ theory of disease?" He apologized and said the rule simply was that all patient-facing meeting required a mask. So there, standards.

If you don't like my source then perhaps you can provide one that is better.

I just reviewed every result on the first page of Google search for: beef greenhouse climate. EVERY SINGLE ONE explains, in one way or another, that beef has a significant and grossly disproportionate impact on the climate. The Economist, Scientific American, The Guardian, Forbes, World Resource Institute, Vox, BBC, Science(published by the American Association for the Advancement of Science), Sciencedirect, the United Nation's FAO, and countless more. Take your pick. Or you could try
Environmental impact of meat production with over 200 sources cited.

Global warming in general, and the impact of beef in particular, are all way past the point where denialism requires actively avoiding and disregard wall-to-wall sources saying the same thing.

If we are concerned about the global warming impact of eating beef then I'm thinking we did so well with the big emitters of coal, petroleum, natural gas, cement, and metal refining, that we are looking to the teeny tiny impact of beef.

If you are bleeding from multiple wounds, I'm sure you know full well that was not a valid argument AGAINST bandaging the easily fixed bleeding immediately, while experts attempt to get the more severe and difficult bleeding under control.

We have not remotely halted global warming. We have barely begun to slow it down, due to decades of sabotage by denialists. The only way we can possibly solve this problem is a few percent at a time in many different ways and many different places. As all of the top Google search results explain, reducing beef consumption is the quickest and easiest thing we can do to immediately and significantly shift things several percent in the right direction. Several percent translates into years of difference, and a lower peak temperature.

As for the rest of your post, I very carefully checked and double checked. Not one sentence was remotely addressed how much impact beef does or does not have. I'm not sure why, but you spent four paragraphs 100% dedicated to arguing that your signature is false and absurd.

Beef is one of the top cause of climate change?

Yes.

I thought I'd look that up and a study from Oklahoma State University says beef production causes 1.9% of the CO2 emissions from human activity.

That's called confirmation bias. You went looking for a specific answer, you ignored all of the reliable sources and all of the evidence contradicting the answer you wanted, and you latched on to the first random thing that kinda-sorta looked like the answer you wanted.

In this case you quote a fragment about CO2, and you utterly disregarded methane. Methane is 25 to 80 times more powerful of a greenhouse gas than CO2, and beef production accounts for approximately one third of all human caused methane in the US.

Beef is indisputably an order of magnitude more environmentally damaging than any other category of food. You could buy anywhere from 10 to 200 pounds of virtually any non-meat food, eat one pound and literally burn all of the rest, and it would have less environmental impact than a pound of beef. Beef is obviously only one of many contributors to global warming, but it is a significant factor.

Global warming is not remotely "solved". Temperatures are rising, we haven't stopped the increase, we haven't even managed to slow the increase. Temperatures are still on a basically straight-line increase. There are various initiatives to eventually try to get things under control, but we're nowhere near achieving that. Temperatures are going to continue to rising for decades to come, because denialists have spent the last decades devoted to sabotage.
