Summary
Last month, the Panama Canal was expanded. The new locks are enormous. This upgrade has costed $5.4 billion. The former canal could accommodate 5,000 containers. Today, the new one has double the capacity. The United States built the canal and 65% of the cargo that uses the waterway has ports as its origin or destination.
Opinion
This upgrade might raise the dominant U.S. position, I suppose. It allows the large ships transporting propane gas to make faster and cheaper carrying to Asian markets. On the other hands, we should consider the influence to surrounding environment like ecosystem. Linking the sea to another lets creatures move alternately. It can break environment. If human exterminate some creatures, can we take the responsibility of it? We must be careful when arranging environment.
