To breathe is such a natural and indispensable gesture that we do it most of the time unconsciously. But do you know where does all this air come from, all this oxygen ? The answer is : oceans !
This answer might come as a surprise given that we usually hear about essential role of trees in the oxygen manufacturing. Would the importance of trees then be exaggerated? We explain everything in the rest of this article.

Trees absorb 1.9 billion tonnes of CO2 per year
You should know that trees make oxygen. Nevertheless, trees also consume almost all the oxygen they produce. But that doesn’t mean trees aren’t important. Quite the contrary. most big role of trees is here photosynthesis.
Photosynthesis is a chemical process that allows the tree to transform carbon dioxide or CO2 in the air into oxygen. As a reminder, CO2 is one of the biggest contributors to climate change. And it is emitted by human activities. However, trees trap CO2 through photosynthesis. And they absorb a large part of it since forests absorb 1.9 billion tonnes of CO2 per year!
Could we still breathe without a tree?
First of all, you should know that trees also attract pollutants emitted by heating buildings and transport. So-called fine particles. Thus, trees clean our air and protect our planet.
In addition, let us not forget that trees are an immense source of biodiversity. They are indeed populated by thousands of animal and plant species. But suddenly, what would happen if there were never any more trees on our planet? Could we no longer breathe?
Well, we could still breathe even if the trees were gone. However, the absence of a tree will considerably complicate our daily life. Not to mention the fact that the non-existence of trees will be a disaster for our planet and our health!
By the way, if you want to address a gesture for our environment, I suggest you install the Refoorest extension, an extension that allows you to participate in the planting of trees around the world.
