Note: I do intend to continue the series on Charles Siegel’s work (he has a new book out) and reflect some more on what Paul Chefurka is doing, but I keep letting other things bubble up. Most recently the discussion that began here and continued with my last post has captured my [...]

Subtitle: remembering to use science to improve technology
Experts say the [expansion of fishing industry] has been driven by growing populations and prosperity around the world. Almost a billion people now rely primarily on fish for protein. [emphasis mine]

The last time I recall the mainstream media seriously talking about overpopulation was thirty years ago. This week, however, one news outlet with a global reach will air a documentary (two parts, four hours total) that will address

climate change,
vanishing natural habitats,
disappearing species, and
human overpopulation.

Tune in your TV to CNN on Tuesday and Wednesday to [...]

Three decades of Earth Days have only mitigated somewhat the destruction we are inflicting on our planet. We are desperate for a government that will take action to halt and reverse course, and we need more people to vote such governments into power.
If you are involved in some task the outcome of which [...]

biodiversity

We don’t know the number of species on Earth. Estimates go into the tens of millions with about 1.4 million having been described.

750,000 are insects
250,000 are higher order plants (flowering plants)
4,000 are mammals (human beings being one of these)

Listen to E. O. Wilson in The Diversity of Life:
