Fish ladders are designed to be placed in places on the migratory path of fish, like salmon, that is gradient in width, with places for fish to rest in the process of going further and further upstream. The fish ladders are known well to be helpful for adult salmon going upstream. In some ways it is mans way of giving back.

It is the continuation of this cycle that creates they swirling mass that a hurricane becomes. It is possible that global warming, caused by human beings, may be responsible for the modern frequency of hurricanes (West, 2013). If this is true then this cannot be good.
