We need dissolved CO2 in the blood to be involved in the chemical reactions which convert highly toxic blood ammonia into much less toxic and excretable urea. Called the urea cycle among other names. Check it out in a basic biochem textbook or online.
I always bring out that fact if some CO2 paranoid bloviator talks about how toxic CO2 is. As mentioned earlier CO2 is plant food. And plants make oxygen...so CO2 is a very necessary commodity.
I had someone say once, after I mentioned how little co2 there is compared to our 6.5 quadrillion ton atmosphere, “well it may be a small amount, but so is arsenic, and a little bit is deadly” lol
The left also love talking about. “Tipping Point” of around 450 ppm co2 in the atmosphere, or whatever arbitrary number they choose, but the fact is that life thrived just fine back when there was far more than twice the current co2 in the atmosphere. It was estimated that co2 back when was around 1000 or so ppm in the atmosphere, and the ,eft today scream about 400 or ppm being “close to the tipping point where all life will cease to exist” or some such nonsense.
There are so,many facts like past enormous amounts of co2 to refute the asinine c.aims of the left today, but sadly the left have deceived the world I to thinking that man is a virus that must lay for their “enviro-sins” by self flaggelation and denial. The world has bought into the ,ie hook line and sinker.
Accordi g to bible prophecy we have more than 1007 more years of life on earth before God destroys it and creates a new heaven and new earth. Life will continue to thrive for at least 1007 years, likely much longer. We are nowhere a “tipping point “ like the lying left claim
