Toxic plastic debris has become a permanent fixture in our food chain, with little attention paid to the potentially devastating effects on our environment and human health.

Toxic debris from plastic packaging kills approximately a million seabirds and more than 100,000 marine mammals each year. The rapid proliferation of plastic products over the past 70 years has led us to the point where more than 8 million tons of plastic are dumped in our oceans each year.

A UN report in 2016 warned that people who consume plastic-contaminated fish may be exposed to chemicals that can cause poisoning, infertility, and genetic disruption.
