World Rivers Day 2021: 8 Interesting facts about rivers you need to know

Observed every year on the fourth Sunday of September, this year the World Rivers Day is marked on September 26. This day is celebrated to raise awareness about the importance of rivers and all kinds of waterways across the globe.

Rivers are a fresh and healthy source of water that provide us with ample resources like energy, food, crops, drinking water and more. World Rivers Day highlights the importance of rivers and aims to increase public awareness around it along with keeping all water bodies fresh and clean, devoid of any toxins.

With the advent of climate change and the increase in global warming, rivers hold great value in restoring the climate of the planet and balancing the ecosystem.  If we continue to pollute the rivers, the ecosystem around them will collapse and perhaps, we will lose one of the most important water units of the world. Rivers offer freshwater environments and it is vital for the wildlife to survive along with creating other means for mankind like transport, manufacturing and energy.
