We are approaching serious thresholds, or tipping points, in major ecosystems.  One example is the projected changes in the vegetation of the Amazon basin, from tropical forest to dry savannah or grassland, due to climate change and deforestation.  The concern is that the Amazon might be caught in a vicious circle – with altered rainfall patterns and increased wildfires – that could bring it to the point of no return, with massive impacts on the world’s biodiversity and climate.
