What kind of problems occurred in building the canal?

The U.S. design overcame both the flooding and excavation problems. Diseases of yellow fever and malaria were dangerous obstacles that had already defeated French efforts to construct a panama canal in the 1880s. Many deaths and hospitalized workers had caused the French to give up on their project.

these include the fossil fuels, oil, natural gas, and coal and nuclear energy. hope this ! ^.^
