A living, bio-degradable （可生物降解的） fabric named "Biogarmentry" has been invented.Made from algae （藻） the textile （纺织品） purifies the air around it through photosynthesis （光合作用）.
Researchers claim it's the first living textile, and have fashioned the material into sheer, cloak-like garment. While prototypes （雏形） like these are still in the early stages of research and design, and far from mass production, they challenge the fashion industry to reimagine ways it can reduce its large carbon footprint through alternative fabrics.
Fashion is one of the world's most polluting industries. It's responsible for more carbon emissions than international flights and shipping combined, amounting to 10% of all greenhouse gasses emitted globally. The crops traditionally used to make clothing absorb carbon as they grow, but most natural materials are still carbon emitters. Take a single T-shirt made of cotton as an example. The estimated footprint of a cotton shirt over its lifetime is 15 kilograms （33 pounds） of carbon dioxide, with most of that emitted during the energy-intensive production and dyeing （染色） processes.
In recent years, environmental start-ups have proposed a number of alternative natural fibres, many Of which have the potential to sequester carbon but none have been shown to achieve zero emissions. As algae has the ability to trap carbon, a carbon-negative raincoat made of marine algae has been created. Algae-based materials are, currently, where electric vehicle technologies were a decade ago. The technology is now ready for prime time. When the resulting garments are commercially available, we can imagine people wearing their own organic cloak, spraying their organism as they go to work and encouraging their algae to purify the air.
