One in three large American rivers has changed colour

A study published in the journal Geophysical Research Letters, has revealed that one–third of rivers in the United States have changed colour in the last three-and-a-half decades.

  • They have changed from appearing blue to appearing yellow and green, indicating the presence of sediments and algae.
  • According the study, sediments and algae are likely to be caused by likely caused by anthropogenic activities.
  • The shift to greener rivers happened in the north and west of the United States according to the study, while the yellowing occurred more in the east, around the Mississippi River.
  • However, according to scientists, the change is colour was not permanent and could be changed with changes to land use as well as conservation measures.
  • The United States has over 250,000 rivers.
  • The longest river in the US is the Missouri river, a tributary of the Mississippi river and is 2,540 miles long. But the biggest in terms of water volume is the deeper Mississippi river.
