How did the Suez Canal and the Panama Canal affect the local ecosystem in their area?
gpt
Panama uses locks to go uphill to a man-made freshwater lake and then back down. It isn't as drastic effect as the Suez.

The Suez is actually making the water saltier on northern Egypt's coast and is killing native species around there and some species from the Red Sea are crossing over.
