7. North America – extinction of the Pleistocene Megafauna 12,000 years ago, the central grasslands of North America harbored an extremely diverse group of large mammals - antelopes, horses, cheetahs, giant ground sloths, mammoths, mastodons Within 1,000 years 33 genera of large mammals had gone extinct in North America This is compared with 20 genera of large mammals going extinct in North America in the previous 3 million years

12. Extinction in Madagascar People arrived in Madagascar 1500 to 2000 years ago and wiped out two giant tortoise species, a bear-sized giant lemur, a small species of hippotamus, several other mammals, and several species of large flightless elephant birds

14. Extinctions in New Zealand Maori’s arrived in New Zealand about 1,000 years ago - hunting together with changes in the landscape due to human use of fire, lead to the extinction of 11 species of moas (large flightless birds ranging in size from turkey to much larger than an ostrich) by 1700; also driven extinct were 5 species of rail and 6 species of waterfowl

15. Small Moa

16. Giant Moa Skeleton – with Kiwi and Ostrich

17. Extinctions in the Hawaiian Islands 44 species of endemic land birds out of 82 went extinct between the arrival of the Polynesians and the Europeans Habitat change was probably important, but so was hunting of flightless geese, ibises and rails

18. Nene – Hawaiian flightless goose

19. Extinctions Following European Arrival in North America The passenger pigeon, heath hen, Carolina parakeet, Labrador duck, and Great Auk were hunted to extinction; bison, beaver, turkey, and white-tailed deer were greatly reduced in population; whales were pursued around the world by New England whalers and many were almost reduced to extinction

38. Use of Plants for Food Medicine in Amazonia The Chacabo use 78.7% of the tree species The Ka’apor in Brazil use 76.8% of the tree species The Tembe in Brazil use 61.3% of the tree species The Panare in Venezuela use 48.6% of the tree species

39. Use of Plants for Food Medicine in Amazonia The Chacabo were first contacted by the Summer Institute of Linguistics in 1955. The Ka’apor were “pacified” in 1928. The Tembe were “pacified” in the 1850’s. The Panare have been in contact with non- Indians since the Spanish explored the middle Orinoco region in the 1600’s.

41. Economic Valuation Alwyn Gentry and Colleagues

42. Calculations $6330 – value of fruit and latex harvested per hectare per year in Peru $490 – sustainable harvest of timber – so total value of $6820 per year $3184 – tree farming in Brazil per hectare per year $2690 – price per hectare of cattle ranching land in Brazil $148 per year profit from cattle ranching per hectare in Brazil $564 worth of medicine per hectare from 30 year old forest in Belize $3054 worth of medicine per hectare from 50 year old forest in Belize
