Trust me.....
...
What gets me is......if C02 levels where much higher in the atmosphere 100 years ago..and they were..that is homeworkable.....
And we Clean it up to more acceptable levels.....
...why do we now Need to give our plants C02 to promote Bigger..healthier plants.....?..........
...does that not suggest we have gone to far...if they Need C02 Supplements.
Coz IMO..plant health and human health are intrinsically linked........
..Thoughts to Ponder........
