A new study published in the journal Environmental Science & Technology has revealed that 90% of the plastic waste found in oceans around the world comes from just 10 rivers. The study, which was conducted by researchers at the Helmholtz Centre for Environmental Research in Germany, analyzed the levels of plastic waste in 57 rivers around the world.
The researchers found that these 10 rivers, mostly in Asia and Africa, are responsible for the majority of the plastic waste that ends up in our oceans. The list includes the Amur, Ganges, Mekong, Indus and Niger rivers, among others.
The study estimates that over 8 million tonnes of plastic waste enter the oceans every year, causing significant harm to marine life and ecosystems. The plastic waste can also end up in the food chain and have potential health impacts on humans who eat contaminated seafood.
The research highlights the urgent need for action to reduce plastic waste and prevent it from entering our oceans. Professor Christian Schmidt, a researcher on the study, emphasized the importance of developing waste management strategies in the countries where these rivers are located to reduce the amount of plastic waste that flows into the oceans.
Overall, the study provides valuable insight into the sources of plastic waste in our oceans and underscores the need for global action to address this pressing environmental issue.
