[00:00:00]Scientists just built a tree that has no leaves, branches, or roots, and it cleans the air better than a real one.

[00:00:05]It's called a liquid tree, and it's essentially a glass tank filled with microalgae, which are tiny organisms that perform photosynthesis far more efficiently than any plant on Earth.

[00:00:15]Here's how it works. Polluted city air is circulated through the water, and the algae absorb the carbon dioxide and release oxygen back into the atmosphere, powered entirely by solar energy. And the reason this matters is simple.

[00:00:27]Cities are running out of space for real [music] trees. In crowded city centers, tunnels, parking lots, and underground spaces, real trees cannot survive there.

[00:00:36]But a liquid tree can sit anywhere. This tree is not designed to replace forests.

[00:00:40]It is designed to work where forests cannot. Do you know of more such examples around? Comment below and follow us for more such content.
