Air pollution kills 7 million people a year. And most of the victims are from developing countries. Large cities in developing countries are lack of green areas so that the air pollution worsened to threaten the residences’ health. It is urgent for them to increase green areas in city in very cheap, fast, ecofriendly way.
That’s why “Tetraforest” was designed. Tetraforest enhances the amount of green areas in cities, by simply using recycled materials. All things that needed to be done are making a wall structure by connecting reused pet bottles with connection parts which are made with recycled plastic, and attaching vine plants on it.
