The current concentration of carbon dioxide in our atmosphere is 0.04%. Before the Industrial Revolution in the 1800s it was 0.03%. 500 million years ado the concentration of carbon dioxide was estimated at 0.40%. Plants and animals prospered.
Zero carbon zealots want it at 0.00%. All plant life dies at 0.015%.
If all plants die, all animals will die.
Humans are animals.
STAND UP FOR CARBON DIOXIDE!
