There's a term biologists and economists use these days — ecosystem services — which refers to the many ways nature supports the human endeavor. Forests filter the water we drink, for example, and birds and bees pollinate crops, both of which have substantial economic as well as biological value.

If we fail to understand and take care of the natural world, it can cause a breakdown of these systems and come back to haunt us in ways we know little about.

UXBRIDGE, Canada, Mar 1, 2012 (IPS) - A global scramble for land and mineral resources fuelled by billions of investment dollars is threatening the last remaining wilderness and critical ecosystems, destroying communities and contaminating huge volumes of fresh water, warned environmental groups in London Wednesday.

No national park, delicate ecosystem or community is off limits in the voracious hunt for valuable metals, minerals and fossil fuels, said the Gaia Foundation’s report, "Opening Pandora's Box". The intensity of the hunt and exploitation is building to a fever pitch despite the fact the Earth is already overheated and humanity is using more than can be sustained, the 56-page report warns.

There are many definitions of resilience from simple deterministic views of resilience anchored in Newtonian mechanics to far more dynamic views of resilience from a systems perspective, including insights from quantum mechanics and the sciences of complexity.  One baseline perspective of resilience sees it in terms of the viability of socio-ecological systems as the foundation for sustainability.  For those that are ready to look beyond resilience as the ability to return to the "normal state" before a disaster, take a look at:
