So I was wondering. When they talk about all the plastic at sea why they don't seem to mention where its actually coming from... It seems if this article is to be believed that they do know where its coming from so the answer to this seems obvious? Even though I do have to agree we do use too much plastic.. But the issue for me is how its getting in to the sea and how we stop that.. Lessening our use of plastic can come later.
Almost all plastic in the ocean comes from just 10 rivers
Most of the plastic in our oceans doesn't get dumped there directly, rivers carry it to the sea. As it turns out, a very small number of them do most of the damage.
At last count, there were at least 8.3 billion tons of plastic in the world. Much of it gets discarded and eventually ends up in our oceans. Researchers are looking for ways to collect that trash in the sea using a variety of technologies but the overall consensus is that using less plastic, or at least catching the trash at the source, would be much better than filtering it out afterwards.
But where to start? Well, in fact, that might be an easier decision to make than one would think. It turns out that about 90 percent of all the plastic that reaches the world's oceans gets flushed through just 10 rivers: The Yangtze, the Indus, Yellow River, Hai River, the Nile, the Ganges, Pearl River, Amur River, the Niger, and the Mekong (in that order).
These rivers have a few key things in common. All of them run through areas where a lot of people live — hundreds of millions of people in some cases. But what's more important is that these areas don't have adequate waste collection or recycling infrastructure. There is also little public awareness that plastic trash is a problem at all, so a lot of garbage, gets thrown into the river and conveniently disappears downstream.
So the problem is huge but the good news is that there is no need to reinvent the wheel — or for some breakthrough technology. Simply collecting and recycling trash as is already being done in other parts of the world (with varying degrees of success) could largely solve the problem.
"Halving the plastic input from the catchment areas of these rivers would already be a major success," said Christian Schmidt, a hydrogeologist at the Helmholtz Centre for Environmental Research. Schmidt was lead author on a recent study that identified the 10 rivers as the main polluters.
Well, let's get started then!
