Document Summary

31 conservation of species and habitats (iii) Not just absolute loss, but how habitat gets broken up. Forests are home to 90% of terrestrial species. 80% of world forests are degraded or destroyed. Climate change in the future might be driver of biodiversity loss loss of arctic fauna amphibians really threatened: disease. Serious now because climate change has made conditions more favourable for disease. Invasive species agriculture losses of -250 billion annually. Kudzu vine lionfish: sometimes raised in aquariums, gets too big so release it into wild, disruptive of coral reef ecology invasive in florida keys and caribbean feral cats, disruptive to bat and bird populations. Drivers in songbird loss implicated in global decline in songbirds, ground nesting birds, turtles, bats: especially problematic in australia, gal pagos islands. 26-fold increase in amount of agricultural pesticide use in last 50 years chemicals used 1000s of km away enter arctic food chain. Pollutants produced elsewhere get transferred to the arctic.
