This letter pretty much sums up my interests, which boil down to: clean air, seaweed, environmental protection, & not marginalising children. https://www.independent.ie/opinion/letters/weve-nine-years-to-adapt-if-we-dont-it-will-be-too-late/41084660.html

โ€˜Itโ€™s a slap in the faceโ€™ โ€“ Irish households are paying twice as much for electricity as data centres Households in Ireland are paying almost twice as much for their electricity as data centres.

Did you know that homes pay twice as much for electricity as data centers do? It's good that that government are helping out the poor scrappy start ups like Amazon and Google ๐Ÿฅน

I feel this so strongly. Covid was a test of our moral integrity & decency -- *not just elites, but all of us* -- and we failed.

I genuinely think one reason Covid has been memory-holed so hard, & so crusted w/ myths & conspiracy theories, is that on some level we know this & are ashamed.

Tess Finch Lees: From the Winter Olympics to Nasa, wearing masks is back โ€“ except when it comes to our hospitals

โ€œMeanwhile, when asked why sheโ€™s masking during chemo, Meg now says, โ€œIโ€™m training for the Olympicsโ€.โ€

Itโ€™s wild that masking in sports is sometimes more normalized than masking in medical settings.

I wasn't going to weigh in on this because there's a lot of other battles rn - but this part of the clip is important.

This is the type of hubris from credentialed folks that we need to end. Airborne viruses don't care whether you have a PhD

Every life is worthy of protection from the spread of airborne pathogens, even if a medal or reaching space isn't on the line.

Our public health systems and healthcare workers have access to the same medical and scientific evidence base as Olympians and astronauts. Respirators are a totally genius invention and should be celebrated and promoted, not disregarded by our health system. www.independent.ie/opinion/comm...

Clean Air, Strategy, Policy, Public Health, Indoor Air Quality, PM2.5, CO2, Ventilation, HEPA โ€” Clean Air Advocacy Ireland As most people spend 90% of their time indoors, we must consider and include our indoor environments as part of our environment when developing a National Clean Air Strategy.

Really positive to see indications of such good air quality in a public building, based on these relatively low CO2 readings of 710ppm. Now, for more public institutions like schools, hospitals & other workplaces to get the same treatment afforded to our public representatives! #CleanAir #Speirgorm

The same as for COVID and evidence on this was given in the Covid inquiry and many parents were fined for rightly protecting their children. The most medically vulnerable children in the UK are the least protected.

@teamlabouruk.bsky.social Around 200 children have lost their lives up
to 2026. Itโ€™s a shame the covid inquiry didnโ€™t cover this period of time as no lessons seemingly have been learnt on child death and disability from long covid. Covid is vascular. Do you think children should be exposed to this?

Norovirus Can Spread Through The Air โ€” Clean Air Advocacy Ireland Here are some tips for avoiding it.

Did you know that Norovirus can be spread through the air? It occurs when infected people ๐Ÿคฎ

There is a surge in noroviral infections in Ireland right now, so we've published this blog with tips on how to avoid #airborne transmission of Norovirus.

I'm very grateful to be able to go to a dentist who is always wearing a respirator and where the CO2 readings on my CO2 sensor are ~800ppm. If nothing else, it demonstrates that they are very well informed, and I can trust them to poke around in my mouth with sharp objects.

Many people hate going to the dentist, but indoor air quality may not be the most common reason.

Unfortunately, not all dental practices are created equal. This Aranet CO2 sensor reading comes into us this #FridayAirday from someone who attended a dentist appointment.

For all concerned about children actually learning in school, see below an interesting study carried out in 270 classrooms over 5 years showing that the measured effects of elevated CO2 in classrooms are greater than the negative impact of school closures during height of the pandemic.

Places like achill and Killarney that are impossible to find a place to live in create their own political consensus. cause the people who can't find anywhere to live there leave and the people who can are often landlords like MHR himself

When this generation of kids grows up, they will never forgive us for doing so little to protect them from the known permanent effects of this virus.

No one wanted to keep wearing an N95/KN95 or bother with air filtration, and all these kids will know we chose convenience over their safety.

I can't stop thinking about this. A conservative average of 1 infection ~2 years for a school going child is ~8 infections by the time they're 18. I'm in Ireland and most children haven't even had 1 course of covid vaccine, nevermind boosters. Who will be well enough to provide healthcare by then? ๐Ÿซค

And yet our governments do nothing to prevent children catching COVID over and over and they have no idea how serious they long term outcomes might be? We are in an experiment of mass infection.

Winter Olympic athletes are rightfully taking COVID-19 precautions - The Sick Times Despite a lack of COVID-19 precautions implemented by the 2026 Winter Olympics organizers in Italy, some athletes, teams, and their loved ones are protecting themselves from airborne pathogens by mask...

It is very encouraging to see elite athletes embracing a simple and effective tool to protect their health by wearing a well fitted respirator at this year's winter Olympics.

These are black boxes prisons designed to eventually โ€œdisappearโ€ people, many who are here legally, into โ€œworkโ€ prisons. Provide them w/barest essentials w/an end game of forced labour they can sell.

I hope this message makes it to more pregnant people. Your placenta is a big olโ€™ vascular organ and if you looked at images of Covid-impacted placentas you would mask up *at least* in pregnancy.
