By 2050 there will be more plastic than fish in the oceans. It’s an environmental crisis that’s been in the making for nearly 70 years. Plastic pollution is now considered one of the largest environmental threats facing humans and animals globally.

In “The Plastic Problem: PBS NewsHour Presents”, Amna Nawaz and her PBS NewsHour colleagues look at this now ubiquitous material and how it’s impacting the world, why it’s become so prevalent, what’s being done to mitigate its use, and what potential alternatives or solutions are out there. This hour-long program travels from Boston to Seattle, Costa Rica to Easter Island to bring the global scale of the problem to light.
