What will happen if there will be no rivers?

Answer 1

If there were no rivers, it would be difficult to supply people with enough clean drinking water. Almost all the drinking water we use comes either directly or indirectly from rivers. There would also be a loss of fish and wildlife, as well as transportation for many industries that use rivers to move their products.

Answer 2

Rivers flow naturally from highlands where the rains fall, to the sea. The exact route of the river is determined by topography and, to a certain extent, by chance.

Ancient civilizations - and many more modern ones - develop around the rivers, and the prime example of this was the Nile. If the Nile River had formed differently, then the entire course of human history and development would have been different. The Egyptian civilization and culture that evolved along the Nile would have been different, in unpredictable ways, which means that the political and social developments in the eastern Mediterranean Sea, including relationships with the Sumerians, the Hittites, the Israelites, the Greeks, Romans and Phoenicians, might have evolved differently.

For example, a minor shift of the the land, perhaps caused by an earthquake or volcano, might have caused the lands currently drained by the Nile to have formed a different river draining into the Indian ocean. This would have caused the course of history to have proceeded much differently than it did. The Nile might never have formed, or might have been a much smaller river, not capable of supporting the Egyptian civilization. Much of what catapulted Egypt to greatness was the need to manage the annual flooding of the Nile, and preserve the flood waters for agricultural uses; it was the first great engineering project of the human race. Without the Nile, this either would not have happened, or would have proceeded much differently.

Answer 3

Life on land would end,

life in the sea would be unchanged.

no rivers = no rain? or no gravity? or no drainage?

Answer 4

there would be no life and civilization.
