The transformation of Earth’s atmosphere: 500 million years ago the Earth was completely different. Oxygen was negligible, the atmosphere was rich in carbon dioxide. Life cannot be imagined in such an environment.

So how did this world become habitable? Scientists have found the answer to this mystery. (The transformation of Earth’s atmosphere)

A joint study by Syracuse, Oxford and Stanford universities revealed that Earth’s atmosphere, oceans and life worked together to drive this transformation. According to the researchers, about 54 million years ago, there was an excess of carbon dioxide on earth. But it is from this time that marine algae begin to play an important role.

Through photosynthesis, algae absorb carbon dioxide from the air and release oxygen in return. This process gradually increases the amount of oxygen in the atmosphere. As a result, the way for the development of life on earth is widened. But at the same time this increase in oxygen changed the chemical composition of the ocean, causing many animals to adapt to the new environment.

The researchers feel that more research is needed on this topic. But this research has uncovered an important chapter in Earth’s history. This helps us understand how Earth’s atmosphere gradually became habitable for life.
