The roots of the human civilizations are mostly associated with the Asian continent because most of the early civilizations developed here, like the Sumerians, Persians, Phoenicians, Babylonians, Chinese, Hindus. These civilizations, especially the ones from the southwestern part of Asia, played a key role in the development of the civilizations along the Mediterranean in Europe, since they were borrowing culture, alphabet, math, lots of inventions, mythology etc. After their cultural traits were accepted in Europe, they started to spread around even more, and gave the basis for the development of lots of other civilizations.

Answer:
Poor planning, and disease
Explanation:
The obstacles that the French faced while attempting to build a canal across Panama were diseases and poor planning. The French dealt with constant outbreaks of malaria and yellow fever, which slowed construction and caused the deaths of thousands of workers. The French also did not take into consideration the geographical differences between the Suez Canal region and the Panama region. The French had succeeded in building a canal at sea level in Egypt, and they mistakenly thought a similar design would work in Panama. However, the difference in the Atlantic and Pacific Ocean sea levels, as well as the difference in elevation of the Panamanian terrain, prevented them from building a sea-level canal. The United States knew about these two problems when they undertook the project. They took preventative measures by reducing the disease-spreading mosquito population and using a canal-lock system to overcome the elevation obstacle in Panama.
