How much trees does it take for a human to breath in a day?

On average, a single mature tree can produce enough oxygen to support two human beings for a day. A human typically requires about 550 liters of oxygen daily, and a mature tree can generate approximately 100 liters of oxygen per day. Therefore, it takes around half a tree's oxygen production to meet the daily needs of one person. However, this is a simplified estimate, as factors like tree species, size, and environmental conditions can influence oxygen output.
