Thanks. I was not aware of this. In any case, the situation in Ireland was apparently aggravated by the actions of absentee landlords. It appears from the chart that Ireland had a much larger percentage of arable land (32%) than the other affected nations. Perhaps if so much of its product had not been exported, possibly the Irish famine might have been less severe or not occurred at all? This goes to the question of whether the potato famine in Ireland was less of natural disaster and more of a human-made one.
