A recent study published in Science estimates that between 4.8 and 12.7 million metric tons of plastic enter the ocean every year, mainly from coastal regions. The researchers used a grand model to estimate the amount of plastic waste entering the ocean and found that it is significantly higher than previously estimated.
Experts warn of physical and toxicological risks from widespread ocean microplastics, calling for 'turning off the tap' on plastic waste. Small changes in daily habits can collectively reduce dependence on disposable items.
A team of researchers from Sea Education Association and institutions found high concentrations of plastic debris in the western North Atlantic, comparable to the Great Pacific Garbage Patch. The study suggests that basic ocean physics explains why plastic accumulates in this region.
