Dams built along the rivers have caused problems for people living further downstream because Question options:
dams are expensive to build
a river can only be dammed in one place along its path.
no fish can live in the rivers after they have been dammed
less water comes down the river to those people once the dam is built.
Help!!
Less water comes down the river than before, and people using the river will most likely rely on the water coming from it, so if a dam is built, then the people will have less water to drink.....
