Your statements suggest you believe humans are the only important life on the planet, and we must tailor the CO2 levels only to suit humans. Life has existed for hundreds of millions of years with no need for humans.
The levels of CO2 in buildings easily exceeds 1000 ppm. Humans survive and thrive in buildings. Plants grow really well.
CO2 is produced when people breathe. Each exhaled breath by an average adult contains 35,000 to 50,000 parts per million (ppm) of CO2 – 100 times higher than is typically found in the outside air (OSA). Perhaps you would like us to ban all humans as extreme pollution emitters.
When China locked down recently, their levels of CO2 quickly dropped by over 7%. That is a big decline and suggests that CO2 is not the problem it is made out to be. Also you cannot say we are having exponential increases when we are talking about going from 300 to 400 or 500, that is a very big exaggeration, and silly math. An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours. This can be written as f(x) = 2x.
In the past CO2 levels increased only after temperature increases. CO2 does not determine temperature, temperate determines CO2 levels. It comes from oceans, lakes and other bodies of water because as temperature increases, less CO2 can be dissolved in it. There are far more levels of CO2 in rock, and dissolved in water, than in the air.
CO2 is not the enemy of the planet. Stupid humans believing the BS other humans tell them, in an attempt to convince them to buy something, are the problem. Most of the world is not buying the BS. The majority of scientists studying CO2 have concluded there is no problem. Your view is tainted by western, "so-called experts" who are trying to change our lifestyles to benefit themselves. The majority of scientists reside in other countries China, India, and most of Asia, and are ignoring the dumb western fools that insist on destroying their economies to buy electric vehicles that pollute the environment in new and more deadly ways.
But then again, you live in Quebec. Quebec wants to convince the rest of Canada and the U.S. to buy their electricity generated by huge dams that have flooded vast areas of the North, and stop using carbon fuels. They are refusing to allow the Western Provinces to pipeline their vast quantities of oil and gas across their province to ship to energy starved Europe and Asia. Perhaps you are very biased against CO2 and carbon fuels for this reason.
