I think that if they decide to take down all the dams in rivers it can be a good thing or a bad thing. There are both positives and negatives in taking down dams. A good thing is that there would be many more fish in the rivers because a lot of them die going through the dams. Wild salmon going through rivers would go up because 92% of salmon going back to the ocean die when they go through the dams. There would be more research in river ecosystems because there would be more fish because they wouldn’t be dying from the dams.
Some bad things about taking dams down now is that the rivers are used to having them there so they have adapted to having that many fish in it. There would be a loss of jobs where they would be taking down the dams because there would be people that work at them. So they would be losing money and work. If they take down dams there could be a lot of flooding in the areas where the dams are.
They make electricity with the dams and if they went down they would not be able to do that anymore and it could mean that they would lose money.
