Numerous studies have shown that hemp captures up to 16 tons of greenhouse gas annually, while trees suck up about six tons.

All hemp in the world? A single plant? An acre of hemp?

Hudson Carbon, a New York research center that studies carbon storage, found that one acre of cannabis plants can store up to three tons of carbon, removing more than seven tons from the atmosphere.

Is it three or seven? Or is the author jumping back and forth between carbon and carbon dioxide without bothering to tell the reader?

“The general balanced reaction for Photo’synthesis Formula according to Kamen and Ruban (1941) is
6CO2 + 6H2O → C6H12O6 + 6O2 + 6H2O
(Carbon dioxide) (Water) (Glucose) (Oxygen) (Water)
Photosynthesis is the process of converting the energy in which solar energy is converted into the form of light which is used in the production of carbohydrate molecules.”

I imagine that 7 tons of co2 is used 3 tons of carbon is retained and 4 tons of o2 is released into the air.
