A new study examined the gastrointestinal tracts of five deceased Indus River dolphins and found them to be heavily contaminated with plastic waste. Ever since the construction of an irrigation facility, Indus River dolphins have been confined to a 750-mile stretch extending from Pakistan into India, causing their population to decline dramatically, according to the WWF. By examining the gastrointestinal tracts of deceased Indus River dolphins, or IRDs, researchers hoped to gain a better understanding of the impact that microplastics are having on the environment and how they move up the food chain. The study revealed that 94.76% of the plastics found in the deceased dolphins were fibers, with more than half being PET. The only way to lower the amount of plastic pollution entering the environment and our bodies is to vastly reduce the production of new plastic.
