A domesticated planet

The abundance of wild animals is regressing speedily as the number of domesticated animals and persons keeps escalating. Such demographic contrast signals that we urgently need to modify our model of subsistence and our interaction with Mother Nature. If we had to choose between a biodiverse landscape and one hosting a monoculture of pine trees with ruminating cattle, many would take the first…

One-two carbon punch of defaunation

I’ve just read a well-planned and lateral-thinking paper in Nature Communications that I think readers of CB.com ought to appreciate. The study is a simulation of a complex ecosystem service that would be nigh impossible to examine experimentally. Being a self-diagnosed fanatic of simulation studies for just such purposes, I took particular delight in the results.

Why We Need to Save Wildlife to Save Ourselves

Cone snail shells: Not just something pretty to look at.

Midway through the new special issue of Science, about the global loss of wildlife, my heart caught on this idea: We now live with a steady, imperceptible loss “in people’s expectations of what the natural world around them should look like,” and “each generation grows up within a slightly more impoverished natural biodiversity.” It’s…
