Watch | Why is the Nile river in danger?

This is the Nile river 

The survival of half a billion people depends on this river 

But the second-longest river in the world is currently facing grave threats from climate change, pollution, and human exploitation. 

Over the past 50 years, its flow has dropped from 3,000 cubic meters per second to 2,830 cubic meters 

Even Lake Victoria, which supplies the majority of the water for the Nile, may dry up as a result of drought, evaporation, and slow tilts in the Earth’s axis.
