Why are they pumping the CO2 back into the lake? It would seem like they’re kicking the asphyxiation scenario can, down the road for others to deal with. It would seem like a controlled release of the CO2 from the lake is as important in risk reduction as is the methane extraction.
I know, climate change places these two million people at risk, by it’s hysterical claims that CO2 is harmful to the earth’s climate. What idiots.
The return of pressurized CO2 to the deep layer of the lake is for the sake of safety and is not done to keep it out of the atmosphere.
