Coasts are very helpful.
they can connect many countries together through which trade prospers 
they can also cause many dispute over the seas
one can farm in coasts as the land may be fertile and thus very helpful
this way it also helps in the economy as trade prospers and well grown crops circulate throughout the country
it does not affect the entire country's climate but just the coast .
