Rugby union in the Marshall Islands is a minor but growing sport.
Due to their small numbers, and scattered island population, they have often preferred rugby sevens to the XV game.
[1] The Marshall Islands' main problems are related to population and geographical factors - their population is 61,963, and lives on 29 coral atolls and 5 isolated islands in the South Pacific Ocean.
All of this makes a rugby infrastructure difficult to construct, and the islands are beset by rising sea levels.
This means they are particularly vulnerable to any possible sea level rises caused by global warming.
