Science and Research

Check out this interactive map showing polluted rivers in the world.

It is wonderful to see that The Ocean Cleanup organisation has now focused their attention on clean-up efforts on land and in the world’s rivers. On May 2nd, 2021, they launched an open-access interactive map with an overview of the 1000 most polluted rivers in the world. This is a challenging subject to investigate, but the authors of the study have used a new model which updated an earlier estimate from 2015 that 90% of plastic waste is attributable to only 10 large rivers.

You can explore the map yourself in the link below. Take a virtual trip to South and Central America, Africa, and Asia, and compare these with other parts of the world. This map emphasizes the massive challenge we all face. The solution certainly lies in clean-up actions, but we must also underscore the importance of good waste-management schemes, recycling, and not least improved awareness among communities, policy-makers, producers and consumers.

Norwegian biologist and professor Dag O Hessen in August 2018: WHAT IS SCIENCE?, WHAT IS RESEARCH?.

His answer was quite simple, but worth keeping in mind: “It is THE SEARCH for truth.”

Most subjects/fields have no final answers, but we keep on searching and researching for the truth. What was true yesterday may not be true tomorrow.

This is very much the case when it comes to marine pollution and plastic debris in rivers and in the ocean. We do not have exact answers on questions like “How much of the plastic in the ocean comes from rivers?” or “How much of total ocean trash is actually plastic?”

What we DO know, for a fact, is that there are thousands of rivers in the world, small and big, absolutely packed, jammed and constipated due to plastic and other rubbish. And we should be a little impatient about doing something about it.

It is cheaper and far more efficient to get hold of the plastic while it’s still in the rivers. Simply because most of it sinks after entering the seas, and becomes more or less unreachable.

We will keep on with scientific studies and constant research for the truth, but HEY GUYS, we already know enough to start DOING something, we know enough to act!

That is also one of the points in this article from GRID-Arendal. Please read:
