U.S. Bureau of the Census Goldewijk and Battjes (1997) Global Change Human Population Land Cover Species Extinctions Global-scale changes that affect the functioning of the Earth System Much more than climate change Socio-economic as well as biophysical Features Reid & Miller (1989)

Distribution of forests – before major human impact
4
Distribution of forests - present
5
West European Heat Wave 2003 30% less primary production 0.5 Gt carbon source Delayed impact of forest crown damage Oxygene depletion in deep lakes Decline of mollusc species richness Extensive wildfires 5% of forests in Portugal, 1 billion
6
Coral reefs diversity hot-spot, high production, carbon sink breeding habitat for pelagic fishes, crustaceans, and cnidaria recreation value
7
Decaying coral reefs increase of temperature, dying of simbiont cyanobacteria fishery turism, collection

Growing coral reefs

Atelopus, small tropical frogs 1950s and 60s: Import of South Africal Xenopus laevis to the developed countries for obtaining reagent for pregnancy test From 1970s: Batrachochytrium dendrobatidis infection of tropical frogs in Central and South Americas, and Australia 2006: 70 Central and South Americal Atelopus species extinct out of 110-112 Climate effect
