Answer:
Explanation:
Air pollution is an enormous problem in many urban areas, but two European architects have developed plant-filled plastic curtains designed to turn building facades into “living walls” that help purify dirty air.
The curtains contain a mazelike network of tubes filled with microscopic algae, which like all green plants remove carbon dioxide from the air while pumping out oxygen via the carbon-sequestering process known as photosynthesis. Air flows into the bottom of the curtains and rises through the tubes, feeding the microalgae along the way.
