My local high school is suddenly all about the proposed ban on single-use plastics — where student-made posters used to proclaim their dedication to gender equality, they’re now all about the evils of plastics. It’s almost like it’s a co-ordinated campaign that originated somewhere else…
But despite the students’ new-found environmental awareness, the ban they favour would make little or no difference to plastic items ending up in the oceans, because the vast majority of the plastic there comes from only ten rivers, none of them in North America (this is from a World Economic Forum report). Jason Unrau reports on his trip up the Yangtze River in China twenty years ago that illustrates the breadth of the problem:
Beginning in Shanghai in the summer of 1999, I boarded a large flat-bottom boat with around 300 other passengers. It would be the first of about a dozen different vessels, that over two weeks ferried me 2500 kilometres to Chongqing.
After taking my first meal in the ferry’s mess hall, served in a Styrofoam box, I searched everywhere for a garbage can. There were none – passengers simply tossed their garbage overboard and without an alternative, I joined in the littering.
The banks of the Yangtze are home to more than 200 million Chinese who treat the waterway as commuter corridor and as I soon discovered, a dump. I took the trip to get a glimpse the fabled Three Gorges, before a hydro-electric project and dam would change the watershed forever. As my trip progressed, however, so did my treatment of this historic river as trash receptacle.
The closer I got to Chongqing, the narrower the river became and the smaller the ferries got. About 10 days into the trip, I exited the dining hall of a different vessel to engage in the daily ritual of reckless Styrofoam abandonment, but to my surprise there was a garbage bin.
Delighted at the prospect that my littering ways on the Yangtze were through, enthusiastically I added my box to a near overflowing bin. As if on cue a kitchenhand exited the dining hall, gathered up the bag and heaved the entire thing overboard.
Like I experienced and begrudgingly participated in creating, the World Economic Forum’s report describes “rivers of plastic” – its analyses of respective outputs and comparisons to garbage island and other samples, could be traced back to their source.
According to the economic forum eight of these rivers are in Asia: the Yangtze; Indus; Yellow; Hai He; Ganges; Pearl; Amur; Mekong; and two in Africa – the Nile and the Niger.
