The main river in Ireland is the River Shannon, 386 km (240 mi), the longest river in either Ireland or Great Britain, which separates the boggy midlands of Ireland from the West of Ireland. The river develops into three lakes along its course, Lough Allen, Lough Ree, and Lough Derg. Of these, Lough Derg is the largest.
Irish tea just might be the national beverage of Ireland. Believe it or not, the Irish drink more tea per capita than any other country in the world. There are over 4 million people in Ireland and 3 million are tea drinkers. The average Irishman or Irishwoman drinks about 4 to 6 cups a day.
Ireland enjoys a temperate maritime climate, due mainly to its proximity to the Atlantic Ocean and the presence of the Gulf Stream. Known as the Emerald Isle, Ireland is so green because it receives a lot of precipitation.
