What would happen to a civilization if the climate changes and rivers dry up or changes course?

Answer 1

When a river dries up the flora and fauna that are related to that river die or find a new habitat, and a predator of an animal or plant that lived on the river would die or leave as well because its main food source is gone. The watershed of that river would loose a lot of water making the entire area near that river dry up and lose much of its vegetation.

Answer 2

A number of things can happen, depending on the local geology. Sink holes can form where water has receded. The ground level itself may lower over time.

The biggest problem that occurs when ground water, and especially aquifer levels fall is that people have less access to fresh water.

Answer 3

If rivers dry up or change course due to climate change, a civilization that relies on those rivers for water, agriculture, transportation, or other resources would face significant challenges. This could lead to water shortages, food insecurity, migration, conflicts over resources, and disruptions to the economy and social stability of the civilization. Adaptation strategies such as investing in water management infrastructure, diversifying water sources, and implementing sustainable practices would be crucial for coping with these changes.

Answer 4

That happens. People adapt. The civilization would need to migrate until they found a new location with the resources they need.

Answer 5

we would all die
