The Human Legacy

“The monies that are going to space exploration should be used to save our own planet right now. We’re in a triage situation. Things are so grim. It’s World War III." 

- Yvon Chouinard (2019)


People today are basically still the same physically, emotionally, and psychologically as those who lived in Catal Hüyük in 6,000 BC, or those who first came to California 30,000 years ago.

Yet now there are 7.6 billion people on Earth and the environment is less rich and abundant than it was during these earlier periods. For as long as humankind has been on Earth, people have changed the planet.

The Earth and Us

The new reality is clearly visible. One of the most striking aspects of photographs of Earth from space is the pattern and color of development. The cities and urban areas are gray and are spreading into the green areas with tentacles like a fungus or disease. It need not be that way, but many poor choices have been made and everyone has contributed to the changes that Earth is undergoing.


A look at each individual’s ecological footprint shows how large humankind’s impact has become. If everyone on Earth were to live as people do now in the United States, four, five, or even more planets would be needed.

First Steps to True Cost Accounting

The chartered accountants in Europe and Australia have taken positive steps. In the UK company directors now have to disclose climate change gas emissions. External costs of energy have been calculated in parts of the EU. And a growing number of economists now understand the issue.

Much more needs to be done in the US and other developed countries to fully implement true cost accounting. My new book, Accountability, offers a clear view of the task ahead. 334 pages 434 notes.

First Successes

The good news is that there have been enough successes around the world to demonstrate that we can do so much better. True cost accounting will help drive the change as people learn they can live well with very few adverse impacts and while restoring damaged environments. To do this, the present “waste-based” economy must yield to a material-efficient closed-loop economy based on sustainable management of renewable resources.

It will not be easy as it will take some significant changes in accounting, finance, and governmental policy. We know how hard it is to remove subsidies once companies, farmers, and ranchers are addicted to them.

For future generations it must be done — and soon.
