The reason Ireland is so green is the weather. Warm wet winds blow in off the Atlantic Ocean all year round, so it rains often and the air stays mild. Grass loves rain. The whole island is wrapped in soft, fresh grassland.
Ireland sits on the western edge of Europe, with the Atlantic on one side. It is shaped a bit like a saucer — low in the middle, with mountains around the rim. From above, it looks like a great green dish.
The countryside is divided into thousands of small fields by hedges and old stone walls. Some of those walls are hundreds of years old, stacked stone by stone with no cement. In places like the Aran Islands, the walls go on for hundreds of miles.
Sheep and cattle graze almost everywhere. Ireland has more cows than people. The lush grass is what makes Irish butter, milk and cheese taste rich and creamy.
