爱尔兰岛面积超过8万平方公里,人口580万。北部六郡170万人,属大不列颠及北爱尔兰王国,即英国。南部410万人,是独立的爱尔兰共和国。全岛除了都柏林等少数港口城市,可称地广人稀。何以至此?究其原因,就要说到一个半世纪以前发生的土豆大饥荒。土豆学名马铃薯,原产南美。南美印第安人为了避免病虫害,要在同一片田地中种植不同种类的土豆。但欧洲人占领南美以后,只引进产量最高的品种。殊不知一旦遭遇病虫害蔓延,土豆就会大面积绝收。
The island of Ireland has an area of more than 80,000 square kilometers and a population of 5.8 million. 1.7 million people in six northern counties belong to the United Kingdom of Great Britain and Northern Ireland. The south of 410 million people, is an independent Republic of Ireland. In addition to a small port city such as Dublin, the island can be described as sparsely populated.

However, after Europeans occupied South America, they only introduced the varieties with the highest yield. As everyone knows, once the spread of pests and diseases, potatoes will be a large area of absolute income.
