Concept note-1: -“There is too much water, the rocks are exceedingly hard, the soil is very hilly and the climate is deadly.

Concept note-2: -The building of the Panama Canal involved three main problems–engineering, sanitation, and organization.
Concept note-3: -The building of the Panama Canal cost the U.S. $352 million four times the cost of the Suez Canal and took 10 years before completion in 1914. The human cost was much higher: A total of 5, 609 workers died from disease or accident during construction.
