E-mail from library: "Snuff has arrived!" (Pratchett's latest.) I go down to get it. On the counter is 1493 by Charles Mann, author of 1491 on pre-Columbian America. I grabbed that. And it's due in a week without renewals, so for once a new Discworld novel can wait. 1493 is on "the world Columbus created", particularly the biological/ecological Columbian exchange of species. I think I saw a reviewer say "isn't this stuff every educated person already knows?" but so far the answer is "no, it's far more detailed". It also points out analogies to modern globalization: if you have a city with people from four continents, it might be Mexico City in the 1500s; if you have Japanese loggers in Brazil, it might also be the 1500s.
Some highlights so far:
( longish )
The beaver would be hunted to near extinction, and replaced as natural engineer by the European earthworm, the long term effects (climax ecology) of which are still unknown. In the short term it can in a few months suck the leaf litter into the soil, killing off plants and animals which depend on litter instead of soil for food. Deforestation and plowing would do their part for pro-European terraforming of America as well.
