Plastics

When the plastic litter in our waterways and on the ground gets weathered and degrades, it eventually breaks down into millions of smaller and smaller pieces. | Plastic specks smaller than five millimetres are called microplastics. | While exposure to air pollutants have been associated with health impacts, including higher risk of respiratory infections, heart disease and lung cancer, science still lacks evidence about how microplastics and nanoplastics are affecting the human body. | Plastic bottles, bags and containers float in the sea and clog landfill sites. | Nanoplastics are even smaller (some are 500 times smaller than a human hair).
