# Human Oxygen Needs Per Day?

hello, introduce my name is Dela. want to ask this because of my concern for the environment. about how many trees can produce oxygen (oxygen unit)? then one natural tree can give a living to how many humans huh? Humans themselves are the natural limit to consume oxygen, how much (oxygen feed) huh?

Good morning Dela, thank you for asking at HealthReplies.com. Humans normally breathe about 12-24 times per minute which every time they breathe about 3-4 liters of air intake. Within a year, inhaled air can reach 9.5 tons of which 23% is oxygen. One tree can produce about 118 kilograms of oxygen each year. So that in a year to support one human, it takes about 7-8 trees.

Even though it is interesting information, this is actually just a rough calculation. Because human oxygen demand can vary depending on many things. If he is exercising, his oxygen needs will certainly increase, if he is anxious, nervous, afraid, or even have certain diseases such as recurrent asthma, his needs increase. Conversely, when humans are relaxed, or even sleeping, their oxygen needs are reduced. Now, each person's own bedtime can vary. There are 7 hours there are 9 hours, there are only 5 hours. Means that the oxygen needed during that time span is different.

In addition, the type of tree, the number of leaves, height of the tree, the age of the tree, all affect the oxygen produced, so even that cannot be fully ascertained. Therefore, it is clear, because we cannot possibly reduce the number of people intentionally, what we can do is plant as many trees as possible on the available land, support environmental and environmental organizations, realize the importance of nature preservation to as many people as possible, and start with something small, like saving paper, saving tissue, and not littering. So, hopefully answering your question.
