According to Simon Dalby, Professor emeritus in the Balsillie School of International Affairs at Wilfrid Laurier University in Ontario, Canada, global politics over the past 70 years has been driven by an overabundance of "firepower," both nuclear and carbon-based.  The first was used by Great Power to threaten incineration of the world, by intention or accident, in the name of "nat...

Nuclear power is being touted as a way of providing clean energy, reducing greenhouse gas emissions and paving the way to a zero-emission future. There is talk of a “nuclear renaissance,” with small modular reactors (SMRs) replacing the gigawatt nuclear behemoths of the past, quickly and at much lower cost.  But the United States’ experience with nuclear, now going back 70 years, turned out to be...

Long-time listeners to Sustainability Now! know that we periodically turn to a focus on plastic, whose production is predicted to skyrocket over the next few decades, as fossil fuel companies look for ways to sell their product.  Plastics are not forever, although they last a long time in the environment and are piling up across the world’s lands and oceans.  Even notionally “compostable” plastics...

Sequoias are among the oldest living things on Earth, and most of the world’s sequoias are in Sequoia and King’s Canyon National Parks.

When you go out into the world and walk on the Earth, have you ever wondered what was beneath your feet ?  Animals and plants, of course, but mostly soil.  Soil is a wonderful substance, an essential element in the riot of life that covers the planet’s continents.  But soil is not without life of its own: a handful of fertile soil is home to more organisms in a than there are people on Earth.  And...

For uncounted millennia, the creatures of the world’s ocean have been hunted, captured and killed by human beings.  For most of that history, however, this was done for subsistence purposes.  Only over the last few centuries, was the slaughter of whales, seals, otters, turtles, sharks and other marine species justified in the name of capitalism and industry.  Beginning in the late 1960s, exposing...

More than 50 years ago, Christopher Stone, a UCLA law professor, wrote a groundbreaking book  Should Trees Have Standing? in which he argued for the right of trees to be represented in courts of law.  Since then, the Rights of Nature movement has taken the world by storm; some countries have encoded such rights into their constitutions.  But what does it mean to say that trees, rivers and animals...

In the face of climate change, jurisdictions across the country and the world have set ambitious electrification goals that will rely heavily on solar, wind and other zero-carbon energy sources.  California is no exception.  Increasingly, the state’s power providers are buying low-cost electricity from vast solar farms across the seemingly uninhabited deserts of the American Southwest.  But those...

Rivers have long been the object of poems, songs, novels, studies, fishers, swimmers, sewage, engineers, farmers and salmon.  In California, rivers and the water in them are the focus of near-eternal political struggle.  And, there is that old saying, attributed to Heraclitus, “one never steps into the same river twice.”  Every river is different, yet there is some human drive to make every river...
