Giải pháp thay đổi khí hậu sa mạc Sahara và giảm nguy hiểm việc dâng cao của nước biển.(The solution for changing the environment of Sahara desert and for reducing the danger of the increasing of sea water level. )

The solution for changing the environment of Sahara desert and reducing the danger of the increasing of sea water level.
Sahara desert is 9 square millions in area. Its climate affect to the climate of all the world.
I propose the ideal for  changing  the environment of Sahara desert by using the direction- giant powder to dig a river about 800 km  from North –West of Africa to the Center of Sahara desert as the picture attached. At the Center of desert we use the giant powder to dig the some big lakes with the depth  that let the sea water can move to the lakes in the Center of Sahara desert .
The sea water in these lakes will be evaporated in order to make rain that can improve the environment of the desert and  at the same time to product the salt that being carried by water way for the maket of the world . This solution can reduce the danger from  increasing of sea water level when climate changes .
