The issue with modern fashion is that garments often use synthetic microfibers that end up polluting sewage systems when washed. Ultimately, these fibers end up in fish that we consume. One study found that a day’s worth of laundry in a city the size of Berlin releases the equivalent of 540,000 plastic bags’ worth of microfibers into the ocean. To make your laundry cleaner (environmentally speaking that is), make sure that clothes you wash most frequently use more natural fibers such as cotton. Another thing you can do is use a mesh laundry bag that slips into your washing machine and captures 99 percent of fibers released in the washing process.
