Here’s How The Earth Got The Oxygen That We All Breathe

The presence of other planets which can be habitable has been our objective for a long time. In the 19 th Century, astronomers thought that aliens might be utilizing canal-based transport connections to pass through Mars.

Right now, we’re residing in an age when researchers can study planets, which are light years far from our solar system, and research study is still going on: we need to find that planet which is good for humans. The greatest issue? Oxygen. We require a world that has Oxygen in the environment so that we could breathe.

But how fortunate we were to get on a planet with Oxygen from the very first minute? The Earth’s oceans and its atmosphere program that the increase to the levels of Oxygen on today was kind of hardback in the day.

How Did The Earth Get the Oxygen That We Breathe?

They have drawn these conclusions: Earth underwent a three-step rise in the oceanic and climatic oxygen levels. The first one was called Great Oxidation Event”, and it occurred about 2.4 billion years earlier. After that, there was the “Neoproterozoic Oxygenation Occasion,” which occurred at about 400 million years earlier. That’s when the oxygen levels reached their modern-day peak– that of 21%.

But just what happened throughout these three periods, that made the oxygen level increase? We still do not know yet. There’s one concept that states that new organisms “bioengineered” the planet, and reconstructed the atmosphere and the oceans with the aid of their metabolic process.

The rise of land plants about 400 million years ago might have increased the Oxygen from the atmosphere through photosynthesis. They took over the photosynthetic bacteria in the ocean, which were the main oxygen manufacturers in the history of the Earth. There may also be other factors, such as plate tectonic modifications or gigantic volcanic eruptions.
