Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea—more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn’t confined to the open sea: it’s in much of the air we breathe and the food we eat. In Thicker Than Water, journalist Erica Cirino brings listeners on a globe-hopping journey to meet the scientists and activists who help her tell the real story of the plastic crisis. From the deck of a plastic-hunting sailboat with a disabled engine to the labs doing cutting-edge research on microplastics and the chemicals we ingest, Cirino paints a full picture of how plastic pollution is threatening wildlife and human health and reveals that the plastic crisis is also a tale of environmental injustice: poorer nations take in a larger share of the world’s trash, and manufacturing chemicals threaten predominantly Black and low-income communities. There is some hope on the horizon, though, with new laws banning single-use items and technological innovations to replace plastic in our lives. But Cirino shows that we can only fix the problem if we face its full scope and begin to repair our throwaway culture. Thicker Than Water is an eloquent call to reexamine the systems churning out waves of plastic waste.
