Rainforests are estimated to provide about 20% of the world's oxygen through photosynthesis. However, it is important to note that the oxygen produced by rainforests is also consumed by the plants and animals living in the forest through respiration, so the net contribution of oxygen to the atmosphere is lower.
little to none.
Scientists are not in agreement on much about the production of atmospheric oxygen, as far as where most of it comes from. Many believe more than half the oxygen comes from phytoplankton in the oceans while many believe that may be less than one third. Most do agree however that rainforests produce little to no atmospheric oxygen, because what is produced by the rainforests is almost wholly consumed by the same rainforests. That leaves seaweed, lake weeds, swamps and land based plants, other than rainforests, (grasses, trees, agriculture and weeds) as the major producers of oxygen in the atmosphere. Rainforests however have other highly beneficial traits and diversity of life not reproduceable elsewhere.

How much oxygen does the Amazon produce yearly?
The Amazon rainforest produces an estimated 20% of the world's oxygen. This equates to approximately 6% of the oxygen in the Earth's atmosphere being produced by the Amazon annually.
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 Brazil is covered by the Amazon rain forest?
The Amazon Rainforest actually covers about 60% of Brazil, making it one of Brazil's most valuable assets. This dense and lush rainforest not only consumes most of the world's carbon dioxide output, but it also in turn releases a great deal of oxygen to the planet.
How much oxygen is produced every year but the rainforests?
Most of our oxygen is produced not by plants, but by oceanic plankton. [Coccoliths are worth a search in your favorite interweb data resource.] And as far as the trees are concerned, the boreal forests are much larger than the tropical rainforest, but obviously mainly in the north. Can't give you any numbers on O2.
What is the fourth biggest rainforest in the world?
The fourth biggest rainforest in the world is the Congo Rainforest, located in central Africa. It covers approximately 1.5 million square kilometers and is home to a diverse range of plant and animal species.
How much wood does the rainforest's provide?
67%
How much oxygen does the Amazon produce yearly?
The Amazon rainforest produces an estimated 20% of the world's oxygen. This equates to approximately 6% of the oxygen in the Earth's atmosphere being produced by the Amazon annually.
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

How much oxygen does a rain forest create?
A rainforest can generate about 20% of the world's oxygen production due to the vast number of trees and plants that undergo photosynthesis. However, this oxygen is mostly consumed by the forest itself and its surrounding ecosystem, rather than being released into the atmosphere.
What does algae in the ocean provide much of earth?
Oxygen
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.
Why is the Amazon rainforest considered the lungs of our planet?
It's described as the long because the amazon rainforest is the world's number one source for oxygen and since we all use oxygen to live it acts as a lung working through our body. We need the lung to help us breathe as we do the amazon rainforest.
How much oxygen comes from the rainforests of the world?
Absolutely wrong, rainforest doesnt produce oxygen at all, it has an OXYGENE TURNOVER, as O2 is released AND absorbed, overall it has almost no impact on the amount of O2 in the world, the only way more O2 is produced than it is consumed is by "Locking" carbon in plants, in other words, the only way for the rainforest to produce O2 is by growing, if it doesnt GROW, it doesnt produce any O2, and if it shrinks, it is releasing CO2.
Why are rainforests vital to our planet?
The rainforest is full of plants. Plants release oxygen and take in carbon dioxide. We take in oxygen and release carbon dioxide when we breathe. Without oxygen we would die. Many medicines are also found in the rainforest. It is possible there are more medicines to be discovered there still, since we have much of the rainforest left to explore.
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.
Name an Australian rainforest besides the Daintree?
1. Stretching from Newcastle in NSW to Brisbane, the Gondwana Rainforest includes large areas of warm temperate rainforest, Antarctic Beech cool temperate rainforest and the largest areas of subtropical rainforest in the world. 2. Frasier Island in Queensland has a sand rainforest, which is quite different from a rainforest based in dirt. 3. Much of the west coast Tasmania is rainforest.
