Extreme Environmentalism

Updated on Wednesday, June 28, 2017

Speaking of Gaia, I read Michael Lind’s Why we should embrace the end of human spaceflight on Salon yesterday with horror. He marshals a bunch of straw man arguments against humans in space, the worst of which is dismissing the threat of a planetary catastrophe:

“A sufficiently large asteroid or comet impact like the one that caused the extinction of the dinosaurs could do the job. But if a massive bolide threatened the Earth, we would send unmanned spacecraft, not Robert Duvall or Bruce Willis, to steer it away or destroy it.”

That’s a little complacent. Even if we ever get perfect asteroid defenses cracked you’ve still got to worry about cosmic strings, strangelets, radiation storms, Von Neumann probes, DNA hackers, the Yellowstone super volcano and anything shown on a Saturday afternoon on SyFi. All of our eggs are very much in one planetary basket.

Take the Gaia hypothesis to its ultimate conclusion: if the planet is a super-organism then humanity is the reproductive system. We’re the best bet to spread life beyond Earth and ensure its continued survival. The asteroid scenario may trigger panspermia but that would be for a lucky few bacteria, not Homo sapiens sapiens.

Colonizing space is difficult, expensive and for most people unappealing. But stop thinking about the planet you’re leaving to your children and start thinking about the universe you’re leaving to whatever our DNA based planetary ecosystem may evolve into.

A real environmentalist would focus on making this planet uninhabitable so we escape before it’s too late.


Republicans and Democrats: Too big to succeed

Updated on Friday, February 24, 2017

The US political system is like daisyworld.

Flower Power Natural World

Daisyworld is a simplified model of the Gaia (Earth as organism) Hypothesis. A planet is populated by black daisies which absorb more solar radiation and white daisies which reflect it. Over time the temperature of the planet is regulated because the white daisies thrive when it’s warm. If it’s too hot the white population booms, increases the albedo of the planet and cools it down again. The black population then surges as the planet cools down and causes lower albedo and thus another round of warming.

This isn’t (directly) a post about global warming or race.

Replace the daisies with Democrats and Republicans. When Democrats are in power Republican voters are driven to the polls and vice versa. Homeostasis is guaranteed. Like daisyworld or the two-body problem it’s a toy system. It’s just never going to produce interesting results.

I think it’s time to break up the big parties (like the big parties should have broken up the big banks). Each party that achieves more than 20% of the popular vote is forced to split into two smaller parties. We have more than daisies. We have the three-body problem.

In addition to introducing some much needed chaos this could also turn the national political climate from us-vs-them to something more nuanced. Yes, there would still be left leaning and right leaning parties but they’d be forced to differentiate themselves through more than name calling and head stomping. We might have a political marketplace of ideas rather than affiliations.

Anything would be better than daisies.
