The thing you're looking at is not a TV screen or a fish tank.

Yes, a tree that you can pour into a cup just like a drink.

People in big cities want more trees to clean the air.

But there's no space for trees because there are too many buildings, too many statues and too many sidewalks.

Yes, it cleans like a tree, it's green like a tree, but

Inside this tank, there is a special mix of water and a secret ingredient called microalgae.

Microalgae are basically a type of organism that lives on water, sun and CO2.

when they breathe inside this tank, pollution goes in and fresh air goes out.

You can put liquid tray anywhere, on any surface, inside or outside.

Microalgae clean the air just like a tree.

And the more it cleans, the greener it gets.

Big Tree is solving the problem of pollution in urban areas that cannot accommodate traditional ways of greening, such as parks and trees.

Just one liquid tree cleans the same amount as a 20 year old tree.

So instead of waiting 20 years to grow a tree, we can plant this in one day.

See, this bench looks nice, but it only has one purpose to sit on.

It cleans the air and it can charge your phone.

Today it's in Belgrade, but soon it will be in Paris, New York and New Delhi.

Because even if we can't plant new trees in big cities, we can always find space for a liquid tree.
