Plastic credits are supposed to support new cleanup projects. Do they? – Grist

Critics say they won’t work, for one of the same reasons carbon credits haven’t…
Microplastic-eating plankton may be worsening crisis in oceans, say scientists – the Guardian

A type of zooplankton found in marine and fresh water can ingest and break down microplastics, scientists have discovered. But rather than providing a solution to the threat plastics pose to aquatic life, the tiny creatures known as rotifers could be accelerating the risk by splitting the particles into thousands of smaller and potentially more dangerous nanoplastics…
Microplastics Are Filling the Skies. Will They Affect the Climate? – Yale Environment 360

Recent studies reveal that tiny pieces of plastic are constantly lofted into the atmosphere. These particles can travel thousands of miles and affect the formation of clouds, which means they have the potential to impact temperature, rainfall, and even climate change.
Plastic has become an obvious pollutant over recent decades, choking turtles and seabirds, clogging up our landfills and waterways. But in just the past few years, a less-obvious problem has emerged…
