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 come 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 impationt 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!
