Ecosystem Modeling

An ecosystem is no more nor less than the sum of individual responses of diverse cooperating or competing organisms to stimuli from events in their environment. Diversity is a sign that there is a high number of stimuli and that the system has become dynamic in response. A great many small parts, making separate and nimble adjustments, solve problems better than a few large parts responding ponderously.

The water wars: California’s salmon vs. agribiz interests

These fish and shellfish are delicious, healthful, and can be eaten with a clean conscience. Still, there’s something missing in my line-up in recent years, and my customers and I miss it terribly: local, wild salmon. Not long ago, Chinook salmon pulled from our cold, clean offshore waters, constituted up to 50 percent of my business. Today: zilch, nothing. That’s because there hasn’t been a commercial salmon season in California and Oregon for the last two years.

The Festival of Life in the Cracks

Weeds growing up through the cracks in the pavement is a fractal assertion of life revealing itself through the cracks of civilization. My neighborhood is indicative of that, and this year’s Festival of Life in the Cracks (March 10) coincided with a meteorologically beautiful day, one of the first of spring’s blessings of warmth and sunshine.

Americans Increasingly Unworried About the Environment

People grasp what their drinking water has to do with them. Overwhelmingly, I think they do not fully grasp what global warming has to do with them – and that’s a rhetorical failure…At the same time that highly effective movements are arranging million person demonstrations in the streets, most of the people who will actually tell their congressfolk whether to vote for change were watching Law and Order SVU.

The Survival Mindset

But lately I’ve been asking myself a different question. What are the best mental patterns of thinking for surviving tough times? There are a variety of ways to look at this issue, and one is looking at who survives when bad things happen in the wilderness, or in dangerous recreational pursuits and why. I’ve taken some of the ideas outlined by Gonzales and added some of my own here.

What is the Minimum EROI that a Sustainable Society Must Have? Part 1: Surplus Energy and Biological Evolution

EROI theory is rooted in the biological principle that in order to survive each species on earth must procure more energy from its food than it expends attaining that food. From this basic principle the importance of energy surplus became evident, as food sources needed to “pay” not only for metabolism but also for reproduction and storage for leaner times. Part 1 of this three part series presents a brief history of the concept of surplus energy and how it has influenced both biological and human evolution.
