So the mega dam on the Blue Nile is needed to light mud huts and goat pens...??....I predict it will be a ecological, environmental, financial, and political disaster...but who cares...
Ethiopians need electricity as much as you or I do. Water for irrigation of crops is also a nice thing to have.
The Blue Nile joins the White Nile at Khartoum to create "The Nile" flowing north through Sudan and into Egypt.
The White Nile is formed in Uganda by the confluence of the Victoria Nile, from Lake Victoria, and Lake Albert. Egypt wants to claim all this water?
If Egypt needs more water, tell them to start using Drip Irrigation instead of claiming ownership of rainwater which falls on Ethiopian lands more than 800 air miles from Eqypt's southern border..
