Learn about quantity.
Here's a quantity equation for you though. About 3 times the amount of CO2 we find in the atmosphere is pumped into a commercial hothouse to make commercial agriculture products such as tomatoes grow better. Ever eat a tomatoe?
CO2 doesn't become dangerous until 50,000 ppm. Currently the atmosphere is 385 ppm. We couldn't put enough CO2 into the atmosphere to be dangerous if we wanted to.
