This picture links to the Great Potato Famine in Ireland that occurred in the late 1840s. The poor farmers in Ireland were dependent upon potatoes to survive. Interestingly, despite the huge number or starving people on the island, huge numbers of crops (such as corn and grain) were exported for profit rather than used at home.
The Great Famine was a period of mass starvation, disease and emigration in Ireland between 1845 and 1852. During the famine Ireland's population dropped by 20–25 percent, one million people died, and a million more emigrated from the island.
Irish Potatoe Famine: The Coffin Ships Ireland is in your hands, in your power. If you do not save her, she cannot save herself. I solemnly call upon you to recollect that I predict with the sincerest conviction that a quarter of her population will perish unless you come to her relief. Daniel O'Connell to the British House of Commons, 1847.http://www.historyplace.com/worldhistory/famine/
