In the more than 90 years since it was built, do you think that the benefits of the Panama Canal to world trade have outweighed the costs in time, money, and human life?

Answer 1

The Panama Canal has repaid its construction costs (capital and human) many times over since its completion.

By 2015, over 340 million tons of cargo passed through the Panama Canal annually, with over 13,000 transits taking place through the waterway.

The Northwest Passage in the Canadian Arctic is still not viable as a commercial shipping route and probably never will be. The alternative to the Panama Canal before it was built was: A lengthy transit around the Cape of Magellan or Cape Horn requires weeks of extra time, and both passages contain many hazards. Winds and Sea States there are very contrary and have claimed many hundreds of ships.

The Panama Canal has likely saved incalculable amounts of fuel, time, ship wear, and sailors' lives.

Before the canal was built, there was only one other option: transhipping goods to trains (and mule trains before that) on one side, then carrying them over the Isthmus to reload them on the other. This process of unloading and reloading ships is costly, time-consuming, and can result in cargo loss due to theft and breakage.

The biggest threat to passengers prior to the construction of the Panama Canal was exposure to Yellow Fever, which is often endemic in Panama. However, one positive outcome of the construction of the Panama Canal was the discovery (by US Army doctors) of how Yellow Fever was transmitted and could be treated, saving at least hundreds of thousands of lives since. There is also a risk of fatalities from accidents in cargo handling and on the rail road.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
