What are microplastics all around and within us

Plastic has become an inseparable part of our lives. So much so that even the food we are eating, the air we are breathing and the water we are drinking has plastic in them. About 300 million tonnes (300000000000 Kg) of plastic is produced in a year. Only about 10% or less of the plastic is recycled. About 8 million tonnes is dumped into the oceans every year and a lot more is dumped into landfills. The plastic fragments that are smaller than 5mm are called the microplastics. There are many steps that can help reduce our exposure, and that of our future generations, to microplastics.
