When Marcus Eriksen co-founded the 5 Gyres Institute and set out to study marine pollution, he discovered that a plastic smog of microparticles permeates the world's oceans, defying easy clean-up efforts. What's more, these microplastics have seeped into the food chain, threatening marine animals and humans alike. Far from being a gloomy treatise on an environmental catastrophe, Junk Raft tells the story of Eriksen's fight to raise awareness and solve the problem of plastic pollution. Eriksen writes of his voyage aboard his homemade junk raft, and along the way he recounts his successful efforts to fight corporate influence and demand that plastics producers take responsibility for a problem they've created. Eriksen provides concrete, actionable solutions and an empowering call for all of us to courageously challenge the status quo for the sake of the planet.
