The non-profit group The Ocean Cleanup has installed a huge, steel-mesh screen on a heavily polluted river outside Guatemala, in a bid to stop plastics and other debris before they reach the ocean.
The Las Vacas river is strewn with mounds of trash deposited by fluctuating river currents. As the rainy season starts, all of it could be swept down stream into the Caribbean, if it weren’t for a device the group calls an Interceptor Trashfence.
