Earlier quoted context omitted.
Nine million on Ireland in 1845?! They tell us the famine was caused by monoculture; they tell us it was a fungus; they tell us it was English land and farm policy; they tell us it was inequality; they tell us it was import quotas. But they never mention that Ireland was horribly overcrowded. Nine million is jam packed horror. At six million today, Ireland should be closed to immigration and paying naturalized Easter…
Really? Ireland has 13% of the population density of England, and around 1% of the population density of Greater London, both of which are keeping their heads above water just fine.
And that's after concentrating a large population in Europe's largest city so that they can at least have a little open space elsewhere.
