Hihd (historical index of human development) = life expectancy + literacy + gdp: life expectancy is increasing, literacy is more common, height is increasing in men => better nutrition from diets. Biosphere integrity (biodiversity loss: long-term capacity of the biosphere to persist under and adapt to abrupt and gradual change , current extinction rates 1000x higher than background rates (de vos et al. , 2014, Conservation biology: genetic diversity = species diversity. Data scarce in some parts of the world and for some taxa: functional diversity = ecosystem fxns that species perform (may be redundant) Identifying planetary boundaries: defines acceptable level of a key global variable, data are sparse/missing for many of these at the global level. Coastal dead zones: massive release of excess nutrients. Forest areas have decreased since 1990 but the rate of net forest loss has been cut by 50%
