In part the article says:
"Invest in nature now, save trillions later: studyAFP –by Marlowe Hood PARIS (AFP) – Investing billions today to protect threatened ecosystems and dwindling biodiversity would reap trillions in savings over the long haul, according to a UN-backed report issued Friday.More than a billion of Earth's poorest denizens depend directly on coral reefs, forests, mangroves, aquifers and other forms of "natural capital" to eke out a living.Unless world leaders take swift action to halt the accelerating depletion of these resources, the result could be hunger, conflict and environment refugees, the study warned."Recognising and rewarding the value delivered to society by the natural environment must become a policy priority," said Pavan Sukhdev, who headed The Economics of Ecosystems and Biodiversity (TEEB) paper released in Brussels."
My conclusion is that, contrary to one popular belief in the US today, we need more, not less, federal and state government oversight of health of natural ecosystems; encluding rigorous enforcement!
