What were the negative and positive effects of the Panama Canal?

When the Panama Canal was created by the U.S. government between 1904 and 1914, they decided to build a lock canal. And that meant that, in effect, every ship that passes through the Panama Canal goes up effectively three steps to 85 feet above sea level. There’s a large dam that blocked the original flow of the Chagres River towards the Caribbean, and then water flows through the locks with the ships. So it’s a massive lake that was created primarily to move ships through the oceans, but when they did that, of course they flooded the entire region. So the entire Chagres River valley, which was a place where there were many small Panamanian communities, was flooded. And a lot of the kind of natural history of the region was lost in the flooding of the canal as well.
