Fewer and Fewer Large Rivers Run Free to the Sea Because of Humans

Large rivers that flow uninterrupted from their origin to their mouth are now rare. A study published in Nature shows that two thirds of the longest rivers on Earth suffer one or more “setbacks”. This is due to the presence of dams, reservoirs, flow regulation interventions or other forms of artificial dams. Based on this data, it is clear that we need a change. In fact, we must consider that large waterways provide food security for hundreds of millions of people.
