1 in 7 Americans experienced dangerous indoor air quality in 2023. April 3, @ECaley will be joined by @cleantechgroup Alex Crutchfield to discuss innovations in wildfire management, and how to measure your building for smoke safety. Register: hubs.la/Q02qCMN10

Each day, I am looking at landmarks and natural formations and their history with the Indigenous Peoples. Today, I am looking at Lake Huron. Lake Huron is one of the five Great Lakes, with a surface area of 59,590 sq-km and 30,000 islands. Due to its size, it was a very important resource and trading centre for the Indigenous Peoples. Around 9,000 years ago, the water level of the lake was 100 metres lower than today. This allowed a land bridge to be exposed that enabled the migration of caribou. Following the caribou, were humans hunting them. Many settlements were found on this land bridge, and in 2008 60 stone constructions were found submerged on a ridge. These were believed to be hunting blinds used by the Indigenous Peoples. There was also evidence of an extensive trade network, with obsidian from Oregon discovered that dated back 10,000 years. Archeological evidence, including a spear point found on a beach in Sarnia, puts the Indigenous Peoples habitation around the lake at upwards of 13,000 years. At the time of European contact, some of the Indigenous Nations on the Canadian side of the lake were the Anishinabewaki, the Cree, Algonquin, Odawa, Wendake, Petun and Mississauga. There were several important gathering places for the Indigenous Nations along Lake Huron, including Aamjiwnaag for the Ojibwa, which was located at the foot of Lake Huron. The Wyandot called the lake Karegnondi, meaning "Freshwater sea" or simply "lake". Many of the settlements around Lake Huron in the 1500s had grown quite large. One had over 100 large structures and a population of 4,000 to 6,000 people.

In my last IRL meeting in March 2022, Sam Molyneux shared the work he, @ECaley & @poppy_health were doing to detect Sars-CoV-2 & their vision to make the spaces where we live & work healthier. The approval👇of @ashraenews Standard 241 is a groundbreaking step in their journey. 👏
📢 @ashraenews's airborne infection risk mitigation standard for buildings has been approved! Standard 241 will reduce disease transmission & promote healthier indoor environments. A huge congrats to Sam, @ECaley & @poppy_health for their leadership shaping this new standard!

Oh, this could be very, very interesting.
"It is a way to take the invisible and make it visible" Toronto is participating in what's being billed as the first ever city-wide program to test and rate the indoor air quality of spaces where people work, shop, and gather. toronto.citynews.ca/2022/11/…

Now do schools and daycares. Let’s test out a hypothesis: many kids and staff aren’t having the normal, stable, enjoyable school year @sflecce promised because the air they’re breathing and sharing isn’t clean. #MaskUp #BreatheEasyTO #onted #SafeSchoolsON
More than 120 indoor spaces in Toronto’s downtown are participating #BreatheEasyTO by testing their air quality. Here’s some of the highest and lowest ranks and how the ⁦@CityNewsTO⁩ newsroom stacks up! toronto.citynews.ca/video/20…

It will never cease to amaze me that machines to literally remove viruses from the air exist and are fairly cheap. Yet humans, even very rich humans in very rich organizations...simply...won't use them during a global pandemic. For...reasons...
