    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease.

    More than one-quarter of the population of Ireland died of starvation or associated disease, or were forced to emigrate. Ireland after the famine was a completely different country in many ways.The direct causes of the famine are simple to understand-a large part of the population of Ireland, mainly the poorest families, had become completely dependent on the potato as a source of food. In 1845, the blight appeared, a disease which affected the potato crop. Successive failures of the potato crop in Ireland led to more than one million people dying as a direct result.What is less easy to understand is why this famine was confined to Ireland and why the British government did not do more to help. The potato blight affected parts of Great Britain and other countries in Europe, but nowhere else did it lead to famine. For much of the famine, food continued to be exported from Ireland, and at its height, there was food stored in warehouses which could have been used to alleviate the suffering of the starving-that it was not represents at the very least a complete failure of understanding on the part of the British government.Inside you will read about...✓ Farming in Ireland✓ The Blight Arrives✓ Full-blown Famine✓ Mass Emigration✓ Poor Laws, Revolt, and the Return of the Blight✓ Aftermath and LegacyAnd much more!The Great Famine left a legacy of distrust and animosity between large segments of the population of Ireland and Great Britain, and this in part led to the movements which finally produced Irish independence.
