The problem with holistic management is it's so profoundly simple, but it's not easy. And it's profoundly simple. You're almost insulting people's intelligence to explain it twice, just about making better decisions of where you want to go in your life, bringing in environmental, social, economic issues simultaneously.

Hard systems are everything we're using right now - computers, phones, planes, the clothes you're wearing, the room you're in. Everything there involves 100% use of technology and expertise to make it, and nothing we make - including space exploration vehicles and so on - is complex. Everything we make is complicated. Nothing is self-renewing.

Ultimately, the only wealth that can sustain any community, economy or nation is derived from the photosynthetic process - green plants growing on regenerating soil.

The problem of a rising population destroying more than four tons of soil for every human already alive needs to find its way into corporate board rooms if we are to enjoy future financial, economic and political stability.
