This is not going to be an effective challenge as while CO2 is not poisonous to humans - as it is part of the air we breath. However in high concentrations (such as escaping from a plastic bag or honey comb like chambers in a rigid plastic or other material... a leak or sudden outpouring of the CO2 gas would cause it to be dominate in the air mix and could lead to unconsciousness and even death in humans and pets - simply because it replaces the O2 in air.. This argument would be thrown back at anyone who posed what the article does... This would work in a similar way even if the gas were Nitrogen another major gas found in air.
Seasonal lake turnovers in Africa and other places has caused huge releases of CO2 gas to come rolling into villages - killing the entire population in a few hours..
And - Please note - I firmly believe that AWG is a totally bogus scam ... And that any Climate Change is a natural occurrence ...
They talk about the climate ‘heating’ and blame CO2 for it. Yes, concentrated CO2 can kill you. Even so, it’s not the problem.
What they purposefully ignore (because they can’t find a way to scam it) is that it is not the gases that come out of the tailpipe, IT’S THE HEAT, MAN.
Every car, every furnace, every AC unit generates tremendous amounts of HEAT. HEAT is what HEATS up the ‘environment’.
Since they can’t get us to do without HEAT, AC, and any type of combustion engine (plus even electric engines create plenty of heat), they had to use something else to scam some money. Ergo ... CO2.
Use CO2 to fill the bubbles in styrofoam panels for building insulation. It will work as good as regular panels and sequester perfectly good carbon for the freebies to feel better about their souls.
Of course you could sequester about a whole city block worth of buildings by burying a bag of charcoal briquets sealed in a 5 gallon plastic paint bucket in the local land fill, but I suspect the greenies would not get the warm fuzzies over that.
