Human intervention reduces the number of fish species in half of the world’s rivers
France: Although the species of freshwater fish in rivers and lakes has been declining rapidly since the Industrial Revolution on Earth, a great deal of research has been done in this regard.
A survey has revealed that the biodiversity of fish in half of the world’s rivers is under serious threat. Sebastian Bruce and colleagues at the Paul Sebastien University in Toulouse, France, have collected data on 2,456 rivers and their basins around the world. In this regard, river statistics have been collected for ten years.
