If only we had tools to help protect our children.

Too bad the public health “adults” can’t get over themselves and figure out how to improve vaccination, masking and clean air uptake.

There needs be publicly available information on how many people these mostly-preventable (e.g. adequate ventilation alone is enough to block at least 3/4 of infections in shared hospital rooms) outbreaks kill.

"They were going to die anyway" lets healthcare get away with so much avoidable harm.
This paper showed the large majority of shared-room COVID transmission events are preventable by good ventilation. The fact that it was published by some of the people who had most strenuously insisted COVID *wasn't* airborne (albeit only after they sat on the data for years) is meaningful as well.
So...sounds like we can say that if you got COVID in a 1 ACH hospital room, odds are at least 50% it would have been prevented if ventilation had been merely adequate, rising to 75% if infection control had done their jobs properly and listened to actual experts even just about ventilation?

Noted.

At this point one should simply assume every action taken by the Ford government is intended to degrade the environment, health, education, housing, and every other public good, and also individual quality of life except as narrowly defined to be "driving more is better".

“We have been asking them and insist that they invest in measuring the air quality in those spaces, schools and school buses, and not leaving it as something for which school boards have to pull from an already overstretched budget,” @mjnabuurs.bsky.social says.

The Doug Ford government dropped tire recycling targets, but consumers are still paying eco fees on tires, and there have been job losses for those who used to collect and recycle tires. This is horrible for both the environment and for workers.

Policy on health is clearly broken - politicized, out of touch, reactive and slow. My recent keynote at the Canadian Biosafety Symposium took a big-picture look at how and why that's happening, and how we can turn things around.

Utterly infuriating! I’m happy to pay that fee to have tires properly recycled—not to increase the profits of the manufacturer while tires pile up, waiting to burn!

I think the denial bubble in which they live is pretty dense and therefore protects them from the risk of consequences or self-reflection.
