Every bit of plastic ever made is still with us—and it’s wreaking havoc on the ocean.

LIFE ON EARTH depends on little specks floating in the ocean. Tiny plankton convert sunlight to energy to form the base of the marine food chain, sustaining all seafaring creatures, from anchovies to whales and the land-based animals that eat them.

But increasingly, researchers are peering through their microscopes at the specks in seawater samples and finding miniscule bits of poisonous garbage instead of life-sustaining mini-critters.

It’s plastic— broken by sunlight and water into itty bitty pieces, but still intact. And now scientists are discovering the implications of one troubling attribute of petroleum-based plastic, known since its invention, but ignored under the assumption that technology would eventually resolve it: Every plastic product that has ever been manufactured still exists.

Only 50 years since we began mass-producing it, our plastic waste has built up into a poisonous mountain we have never really learned how to deal with. It makes up 10 percent of California’s garbage, is toxic to burn and hard to recycle.

Out in the Pacific Ocean a vortex of trash swirls and grows, forming a garbage dump twice the size of Texas.

Sea turtles choke on plastic bags, mistaking them for jellyfish. Albatross parents ingest lighters and plastic shards along with squid and small fish, regurgitating them into their chicks’ open throats, eventually killing them.

Shrimp, jellyfish and small fish eat the particle-sized plastic debris that look a lot like plankton, and which, in some places, are three times more abundant than the real thing.

A 2004 report from the congressional Commission on Ocean Policy identifies synthetic marine debris as “a serious threat to wildlife, habitat, and human health and safety,” calling for a set of immediate measures to address the crisis. A growing number of decision-makers are finally paying attention, positioning California to lead the world in staunching the flow of plastic to sea.
