Ireland is a large island located in the North Atlantic Ocean. It is separated from Great Britain to the east by the North Channel, the Irish Sea, and the St George's Channel, which are all navigable. Ireland is the second-largest island in the British Isles, the third-largest in Europe, and the twentieth-largest island on the planet. It is also the most populous country in the European Union.
Geographically, Ireland is split into two parts: the Republic of Ireland (formally known as Ireland), which occupies five-sixths of the island's land area, and Northern Ireland, which is a constituent of the United Kingdom and occupies the remaining third. Its population was about 6.6 million in 2011, making it the second-most populated island in Europe, behind Great Britain, according to the 2011 census. In 2016, there were 4.8 million people living in the Republic of Ireland and 1.8 million people living in Northern Ireland.
With relatively low-lying mountains around a central plain and numerous navigable rivers flowing inland, Ireland's topography may be described as follows: A result of the moderate but variable environment, which is devoid of extremes in temperature, the country has a rich and diverse vegetation. Forestry now accounts for approximately ten percent of the island's land area, compared to an average of over thirty-three percent throughout Europe, and the majority of it is non-native conifer plantations. There are twenty-six terrestrial mammal species that are endemic to Ireland that are still alive today. As a result of being affected by the Atlantic Ocean, the climate of Ireland is extremely moderate, with winters being warmer than would be anticipated for such a northerly location, while summers are cooler than those in mainland Europe. There is a lot of rain and cloud cover right now.
