Home by Bill Bryson - not the first thing you might think of but tells fascinating story of Frederick Tudor who spent a fortune in 1840s taking ice from Lake Wenham in New York State and persuading the world you could refrigerate food from America across the Atlantic.

With the completion of the Erie Canal, buffalo, cattle and wheat from the Great Plains could arrive in Chicago, be butchered, kept in giant ice warehouses then shipped in box cars and boats lined with ice across the lakes, down the canal, out NY harbour and across to a Europe that was experiencing a massive population growth (1848 revolutions).

This first wave of globalisation dropped food prices globally causing (by the 1870s) massive economic collapses and shifts away from failing farmlands. British landed gentry never recovered, and the links to WWI are clear.

The US civil war would have been very different without the Erie canal if the worlds food supply went south down the Missiippi to get out to the Atlantic

All because someone liked Christoph in Frozen and want to sell ice.

Bryson is a brilliant author and this one of his best.
