What additional information are you looking for on the topic of environmental pollution?
This is a sad reality in many countries in Asia. For example, the Mekong Delta rivers in Vietnam are so full of garbage (mostly discarded bits of plastic), that motorboats often get stuck because their engines get caught onto pieces of trash. The story is similar in China, Cambodia, Bangladesh, India… It starts at the individual scale and ends with massive industrial waste going into the rivers as well. And then we wonder why things like the Pacific Garbage Patch are such a serious issue in our world today.
