Actually, rainforests (or any other type of forest) are not a source of net oxygen production.
As vegetation grows it creates oxygen from CO2. The carbon is used to build the plant and the oxygen is released, but, when a plant dies the opposite happens. As it decomposes it produces CO2 and absorbs oxygen as the carbon in the plant recombines with the oxygen. In a mature forest, as rainforests are, the growth and decay are in balance and the net production of oxygen is zero.
As a forest grows carbon accumulates in its plant material, but, as deforestation occurs there is a net loss of plant material and CO2 is released.
The myth that rainforests produce "28% of the world's oxygen" simply is not true.

How do the elements in the human body compare to elements in the earths crust?
the chemical composition of human beings are similar to that found in the reminisce of stars after they impload this answer is correct human beings cant be chemically composed like earths crust because we arent formed from silicates and crystals

Why do you need rainforest?
We need rain forests for our air supply. Much of our food comes from there.Much of our animals in the world live mostly there.Much of our stuff comes from the rainforest's.
How much of the worlds oxygen do rainforest's produce?
the answer is not nearly as much as people would imagine. the truth is the majority of the planets plant based oxygen production/carbon neutralization comes from ocean based blooms. Forest as such produce around 25% on average but you should also consider that the Taiga forest for example (that nobody ever talks about) absorbs more carbon and produces more oxygen than all the other temperate and tropical forests on the planet combined. This probably doesn't sit too well with Amazon conservationists but they should realize and focus on the real ecological damage done by deforestation there - which certainly ISN'T large scale oxygen depletion.
How much of the earths land surface was covered by rainforest 100years ago?
Approximately 12 million square kilometers.
How much oxygen is produced by a tree?
a lot of oxygen! that's where most of it comes from!
How much is the earth atmosphere is made up of nitrogen and oxygen?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
What planet has a nitrogen- oxygen atmosphere?
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Where is oxygen most commonly found in?
under the earths crust in trees and everywhere you can think of pretty much
Which rainforest produces half of the world's oxygen?
Cathy is right about no rainforest producing half of the world's oxygen, but she is absolutely wrong about plants not providing a significant amount of oxygen. The truth is that 98% of the world's atmospheric oxygen comes from plant life. Half of that 98% comes from phytoplankton in the oceans. The other half comes from plant-life on the surface. So, no individual rain forest can account for anywhere near half of the oxygen. In fact, it is now believed that rain forests are oxygen neutral meaning they use as much as they produce (after all, there are innumerable species and animals in the rain forest). William Winner I don't believe that any rainforest produces anywhere near that amount of oxygen. I am terrible with names, but I had the opportunity to ask a very highly acclaimed and reputable scientist about oxygen-making plants, leaves, etc. His response got my attention. He said that plants do not provide a significant amount of oxygen, and rainforests do not provide a significant amount of oxygen. He said it is a myth that they produce anywhere near a significant amount of oxygen. Probably perpetuated by someone who is trying to save a rainforest, and they are trying to think up reasons why we should think they are valuable and worth saving. I happen to be a person who loves forests of all kinds, and who wants to see forests instead of shopping malls! However, I love the truth. Very likely the truth about the rainforests is that their greatest value is to provide habitat for marvelous animals and plants. I also believe that people have not fully explored the possibilities inside a rainforest. There are probably new species and varieties of plants, animals, birds, insects, etc. that may potentially be valuable to us. I believe that a rainforest has a great deal of value to us as the rainforest it is. I don't believe it has much value as a source of oxygen for human beings. But there are so many other great values contained inside the rainforest that I see no reason to try to make up things about it! Cathy Williams
What will the earth be if the rainforest region turns into desert?
If the rainforest were to all disappear, life on earth would soon be extinguished as we know it. Much of the oxygen that humans and other animals need is produced by rainforests.
How much oxygen does the Amazon produce yearly?
0.01 percent of the worlds oxygen is from the amazon
