What are the advantages and disadvantages of the u. S. Being surrounded by the atlantic and pacific oceans on each coast?

Listed below are some of the advantages and disadvantages of the Oceanic Borders of the United States of America.

Advantages:

The access to the ocean on both sides means that the U. S can trade with most countries of the world and so oceans are a source of economic activity. The oceans make the U. S incredibly difficult to invade and also provide security from the threats of other countries. The natural resources on the ocean floor are also invaluable.

Disadvantages:

Since it has a big coastline, the U. S has to maintain a large navy for security reasons and is costly. The flooding and hurricanes are a constant threat in some of the coastal areas and the effects of climate change could be felt strongly.
