The clothing industry uses many toxic chemicals to dye fabrics, which pollute rivers and oceans. A new company is using biology to create clean, natural colors.

They put natural genetic codes into bacteria and grow them in large tanks, very much like brewing beer. This biological process doesn’t need toxic chemicals and uses much less water and energy. On some fabrics, it saves up to 77 percent of water and reduces carbon emissions. The company tests every new color carefully to make sure it is safe for human skin and doesn’t fade in sunlight or washing.

Big fashion brands are now starting to use these new biological dyes. The company’s boss believes we should stop using harmful chemicals for clothes because nature can make every color safely.

Difficult words: dye (a substance used to change the colour of clothes, hair, or other materials), brew (to make a liquid drink by mixing ingredients and letting them sit in liquid, fade (to slowly lose brightness, strength, or colour over time).
