When this does occur the pathogen will easily spread to other crops and destroy the plantation. This is significant because if the plantation for a crop a ruin, society needs to find a new food source and this will be especially difficult if the society depended on that specific crop. One example of how lack of genetic diversity can ruin a civilization if the Great Famine of 1845. In the article Irish Potato Famine (1845–1849), “The famine was due to the appearance of "the Blight" (also known as phytophthora)—the potato fungus that almost instantly destroyed the primary food source for the majority of the island's population. The immediate after-effects of the famine continued until 1851. Much is unrecorded, and various estimates suggest that between five hundred thousand and more than 1 million people died in the years 1846 to 1849 as a result of hunger or disease” (encyclopedia). Because of the lack of genetic diversity, socially the people of Ireland suffered greatly because they had no other source of food, and the lack of diversity made all their potato crop vulnerable to getting attacked by
