How Much Oxygen Does a Tree Produce? How Much Oxygen Do You Need?

A 20 inch diameter tree sucks up 157 pounds of carbon dioxide and then releases 115 pounds of oxygen back into the air every year.

The average human requires approximately 400 pounds of oxygen per year which means we need four trees for every human in order to more than meet our oxygen requirements.
