  • The study found that EVs produce fewer non-exhaust emissions in heavy traffic situations. However, when roads are clearer, their greater weight can lead to increased particulate pollution compared to gasoline vehicles.

    EVs do have one downside brought by their extra weight, more brutal torque delivery and superior power compared to gas cars: their tires wear out faster. This is also a source of emissions that affects air quality. However, while EVs can’t escape the physics brought by their extra heft, their tires don’t wear out anywhere near as quickly as some deliberately misleading headlines might have you believe, although there isn’t a definitive number stating how that’s different from a combustion car.

    They shed less particulate matter overall, but they still wear through tires faster. Both of those articles are about how great regenerative breaking are, and don’t say that electric cars produce less tire dust.

    [Referring to the Tiananmen Square Massacre] We (at least many of us) have read the sources that have been linked. What is described there, particularly the accounts of people who were there, is what we assert is what happened. In the few instances where there may be contradictory first hand accounts (and mostly, the accounts are not contradictory but rather corroborate each other) there may be some ambiguity. But even taking that into account, it is ridiculous and downright ahistorical to say “Chinese authorities massacred people.”

    This is from a conversation with the kind of people I would consider “tankies”. It’s from a community I think has since been deleted, but the general vibe of the comments in the post was that the Tiananmen Square massacre isn’t a real thing and any civilian deaths were actually justified.

    The tree on the right has that block missing in its shadow, the trees on the left are casting their shadows in a slightly different direction, and they guy on the dirt path’s shadow seems too dark and clear. Once you pointed out something was wrong, it’s hard not to see other mistakes.


  • It’s important to know that both the FDA and the USDA are in charge of inspecting food, and which food is covered by which agency can be complicated.

    FSIS [under the USDA] conducts continuous daily inspections of foods in its domain, whereas FDA inspections have no regular schedule. The FDA is more likely to inspect only after a tip about a possible food safety violation, so random inspections can occur up to 10 years apart or, in rare cases, not at all.

    “It’s not that they don’t want to inspect more, they just don’t have the funding,” Raymond says.

    This inspection imbalance means that pepperoni pizza, because it contains meat, has ingredients that will be inspected three times before the product hits the grocery store freezer: at the slaughterhouse, the packing plant and the pizza factory. A vegetarian pizza produced at the same facility, however, will probably not undergo any inspection.

    And in regard to the FDA being not allowed to regulate:

    [The Dietary Supplement Health and Education Act of 1994] placed the burden of proof concerning dietary supplement safety on FDA, requiring the agency to show that a dietary supplement ingredient is adulterated rather than requiring the manufacturer to prove a supplement is safe prior to marketing. This is in contrast to new food additives, which require submission of safety information in a food additive petition prior to marketing, or drugs, which generally require submission of safety data as part of a new drug application prior to marketing.

    At least with dietary supplements, they can’t make a new product guarantee it’s safe, the FDA needs to already know something is dangerous before it can force a recall.
