LIFELINE RIVERS

1. What is a River?

A river is a natural stream of flowing water that moves from higher elevations to lower areas under the influence of gravity. Rivers originate from glaciers, springs, lakes, or rainfall and ultimately drain into seas, oceans, or lakes. They provide water, food, energy, transportation, and support life.

2. Why Rivers are Important?

Rivers are vital for human civilization and economic development. They supply drinking water, support agriculture through irrigation, generate hydroelectric power, facilitate transportation, maintain biodiversity, and hold cultural and religious significance. Rivers sustain ecosystems and provide livelihoods to millions of people across the world.

3. Save Rivers, Save Life

River conservation is essential for environmental sustainability and human survival. Preventing pollution, reducing waste disposal, conserving water, protecting riverbanks, and promoting afforestation help maintain healthy river ecosystems. Protecting rivers ensures clean water, biodiversity conservation, agricultural productivity, and ecological balance for future generations.
