Not enough green areas in your city? A team of Serbian scientists may have the answer: a "tree" in liquid form that they say could help improve urban air quality.

00:00 It has no leaves, no trunk and no roots, and yet this unusual contraption acts like a tree.
00:08 This green aquarium in the centre of Belgrade contains microalgae that bind carbon dioxide and produce oxygen using photosynthesis.
00:17 Its inventor is biophysicist Ivan Spasojevic, who is looking for an alternative concept for green spaces.
00:25 The first important thing is that the liquid 3 does not serve to change the tree.
00:31 The liquid 3 is designed to target areas where you cannot put a normal tree.
00:35 For example, here where we are standing now, we have two trees, and the space between them cannot be used for a third tree,
00:39 because the cross would bend and the tree could not grow.
00:42 The liquid 3 is also multifunctional.
00:47 It serves as a bench, includes a charger for smartphones, and has a solar panel that generates power for street lights at night.
00:55 As it purifies the air, the green colour becomes stronger.
01:01 The goal of the liquid 3 is to send a message that it is important to fight for better quality of urban air,
01:06 that the protection of the environment is important, and I think that the liquid 3 is sending such a message.
01:12 So far, two liquid 3s have been installed in the capital Belgrade and one in the city of Uzice,
01:18 and there are plans to plant more.
01:21 There is also considerable interest from abroad.
