Changes happening in ON public schools.
Teachers being laid off due to Fraud PC funding cuts.
Underfunded education just means more kids go without.
This sucks.

Apparatus for mesuring CO2 from 1865 and Text in German "Obwohl Kohlensäure nicht die einzige Luftverunreinigung darstellt, ist das Vorhandensein und die Konzentration dieses Gases in der Regel der beste chemische Indikator für die Belüftung von Räumen, die durch die Ausdünstungen von Personen beeinträchtigt wurden." ‘Tests for Carbonic Acid & of Ventilation’ (1865) In ‘AIr AND RAIN’ (1872) By R. Angus Smith Original from https://dn790000.ca.archive.org/0/items/airrainbeginning00smitiala/airrainbeginning00smitiala.pdf Page 202
1865 R. Angus Smith used CO2 mesurement as an indicator for air quality 😍
"Although the only impurity in air is not carbonic acid,
as a rule the best chemical test for ventilation of rooms rendered impure by exhalations from the person is the presence and quantity of this gas."
