I recently read an article that described how dirty the world’s major rivers were. It seems that more than two million tons of plastics are transported to the oceans by them. About 122 rivers contribute 90% of the plastic found in the oceans, and 103 of these rivers are in Asia. Twenty rivers in Asia contribute 67% of the plastic.
The problem of plastics in the oceans is such that the United Nations world conference on the oceans has decided to take a serious look at it. More than 80% of what is found in the oceans consists of plastics, most of which comes from the continents.
Because the use of plastics is a recent phenomena its influence on the oceans began to be scrutinize only around the year 2000 by scientists. It was then that continents of floating islands of plastics were discovered and are now well known.
That Asian rivers are heavily polluted is no surprise, especially considering the rapid pace of development since the 1970’s and 1980’s. Perhaps by pointing out the obvious at the United Nations world conference on the oceans solutions will be presented and the Asian nations will seek help as a lot of these countries are still too poor to embark alone on a program of cleaning up their rivers.
