When I was a kid I was told this myth in style of story that I should not go under trees in the evening because there used to live some evil spirits. My curious nature made me go under the tree and I felt some pressure while breathing so I run away from there. Later on, when I learnt about the reason in my science books, I laughed a lot. Today, I'm reading about something that seems not done before or at least is least known to most of the people.
This is true:
Thanks to photosynthesis, our microalgae can capture and transform carbon dioxide into oxygen, which reduces greenhouse gases and thus contributes to the slowing down of global warming.
Very good work @calprut.
