A filter-feeding adult humpback draws in nearly 19,000 liters of water and one and a half tonnes of krill each day. “Imagine how much plastic they trap.”
Scientists have a new way to estimate how often ocean animals get tangled in plastic — and it could explain why so many whales are washing up dead

- An average of about 8 million tons of plastic enters the ocean as pollution annually, though the maximum amount could be closer to 14 million tons.
- Whales and other marine animals can confuse plastic items for food and consume them, or get entangled in plastic nets. This can lead to strangulation and death.
- A new study shows that the amount of plastic in the North Atlantic Ocean has increased dramatically since the 1990s, and the number of plastic entanglements increased 10-fold between 2000 and 2016.
Happening around the world...common denominator???
If it’s clear whales are eating microplastics, says Sarah Nelms, a postdoctoral researcher at the University of Exeter in the United Kingdom, a key question becomes: what are microplastics actually doing to these animals?
In her own studies, Nelms has found microplastics in the guts of 50 marine mammals from 10 different species stranded around the coast of the United Kingdom—every animal she and her team examined.
