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).

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!

Which biome has half of the worlds species?
Rainforests are the type of biome that has half of the worldâ??s species. They also produce nearly half of the worldâ??s oxygen.
What part of the worlds rainforest has been cut down?
half of it
Who controls half of the worlds oil?
Siberia definitely produces most of the worlds oil
Which country produces nearly half of the worlds mangoes?
India does.....
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.
What country produces more than half of the worlds mango crop?
India
What organisms produces about half of the oxygen on earth?
trees
What organism produces about half the oxygen on earth?
trees
What country has the worlds largest rain forest?
The largest rainforest is the Amazon. It spans several countries in South America, but half of it is in Brazil.
What is a rainforest is?
A forest has to have 150 cm of rainfall a year before it is officially a rainforest. There are 4 layers to a rainforest, the forest floor, the understory, the canopy and the emergent. Nearly half of the worlds plant and animal speicies live in the rainforest.
What country produces half the worlds cork?
Portugal produces over half of the world's cork, particularly in the Alentejo region. Cork oak trees grow abundantly in Portugal's climate, making it the leading producer of cork products globally.
What south American country is home to almost half the worlds rainforests?
Brazil - although it's sad to know that the Amazon Rainforest is being decimated through "progress'.
