1/9: A few years ago I picked this book by @LyandaHaupt up in the bookshop haven of Hay-on-Wye in southeast Wales, but have only just now read it. For me the author really hit home how #Darwin was able to construct the theory of evolution, arguably...
2/9: one of the most important scientific theories we have, through extensive observations of the “natural” world. While some degree of modest experimentation was involved (though that too was rooted in nature) it was his meticulous observations of nature,...
3/9: his closeness to nature, that inspired his vision of the tree of life and the mechanistic details of evolution. It’s also what led him to the realization that humans aren’t separate from the natural world.
This realization also contributed to...
4/9: biologist E. O. Wilson’s (@EOWilsonFndtn) formulation of the concept of #biophilia (that humans have an innate connection to nature as a result of our evolutionary history). It also contributed to self-proclaimed “nature nerd” @JanineBenyus'
cofounding...
5/9: of the @BiomimicryInst, where nature is used as a source of inspiration for solving current human challenges. Both #biophilia and #biomimicry are increasingly being incorporated into the design, construction, and operations of modern built environments, making...
6/9: our buildings more sustainable and healthy in the process. And their applications extend outside of the AEC Industry.
Near the end of the book, the author quotes Rachel Carson in a meeting with several women journalists in 1954: “The more clearly we can focus our...
7/9: attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.” You might even say, the less taste we shall have for ITS destruction. Environmental education (of children and adults) is a critical conduit for providing...
8/9: that focus, providing those personal connections to the non-human built world around us, showing our place within that world, and how we are dependent on it.
9/9: Such environmental awareness leads to a more sustainable or even regenerative mindset, & ultimately an acceptance of the urgency to address climate change.
So all of you environmental educators out there – you rock.
Our new office policy we're finalizing essentially takes this viewpoint. In 3 of our offices, we've assessed high vaxx rates combined w/ addressing the Delta far field risk via ventilation/filtration is adequate enough for vaxxed employees (almost 100%) to go sans masks. 1/
Even in metro areas currently deemed by the CDC as having high or substantial community transmission.
To have vaxxed employees go sans masks in our other 2 offices, relative to their current lower office vaxx rates, the Delta far field risk needs to be addressed through... 2/
some combination of additional ventilation/filtration improvements, increasing vaxx rates, setting lower occupancy limits, or having non-vaxxed employees WFH - we are still assessing the best path forward for each of those locations.
. That we haven't had more districts close for a period of time is pretty fortunate considering everything. 2/
That we're still arguing over the basics of how to respond to a pandemic driven by a predominantly airborne virus demonstrates a multi-level failure of public health & government, exacerbated by a history of underfunding public health, public education, current levels of... 3/
A few questions for the UV specialists. 1st, are the studies/modeling that have been done so far relative to Far UVC impacts on eyes/skin sufficient to answer questions regarding a) potential negative impacts from chronic (continuous or repeated) exposure,... 1/
b) age/developmental specific concerns related to short term or chronic exposure, & c) concerns for those w/ pre-existing eye/skin conditions after experiencing short term or chronic exposure?

This is an all hands on deck moment. In-person school is starting. W/ the #DeltaVariant, even w/ the majority of the relevant strategies in place, it’s going to be difficult to prevent transmission in our schools (linkedin.com/pulse/in-perso…). 🧵1/
In an elementary classroom w/ unvaxxed students, generally ASHRAE compliant ventilation/filtration, the addition of (1) portable HEPA filter unit, & theoretical 100% mask wearing (double layer cloth mask), max exposure is only about 1.2 hrs before an additional student... 2/
is potentially infected at full occupancy (assuming 1 infected student is present).
Accounting for the potential reality of younger kids not always effectively wearing their masks (50% mask wearing), the max exposure is under an hour before an additional student is infected. 3/
These are the type of actions our pharmacies, hair salons, retail stores, offices, universities, k-12 schools, individual residences, etc., need to be taking, particularly w/... 1/

CO2 levels can be used to estimate ventilation levels, though it's important to account for factors like the number of people present, the size of,... 2/
the space, & the use of portable air cleaners. Pages 23-24 of this document from @HarvardChanSPH & @j_g_allen provide a means for estimating ventilation rates based on measured CO2 levels. 3/
I would challenge your point that “No matter what we do, resources will remain scarce and people will compete over them.” First, there’s an abundance of evidence from the archaeological, historical, & contemporary ethnographic records of individuals & groups cooperating... 1/
(employing some or all of Ostrom’s principles) to survive in environments of scarce resources (& not just hunter/gatherer groups). Not saying the evidence for competition (including violent competition) isn’t also there, or that the competition between groups isn’t also... 2/
what often drives the cooperation among group members (because it does), only that cooperation seems to have been most effective when these principles are applied (even as part of a larger competition between groups).
