Through the effects of HIPPO, driving human induced loss of biodiversity and global climate change, our Earth continues to accumulate a vast "ecological debt" that must soon be repaid in full with "compound interest"; to prevent overshoot, we must 'drawdown' human consumption of natural resources, if our planetary ecosystems are to recover with enough time to sustain themselves for future generations. What is the term used to describe the accumulation of this ecological debt?
