The Certainty

Happy Earth Day, everyone. Some thoughts were provoked by a timely piece by Patrick Moore, a co-founder of Greenpeace. He writes about why he left the organization.

Moore is a scientist, trained in the scientific method. He doesn’t have what I call The Certainty. His colleagues did. They were more rigid, more ideological. More Certain.

The breaking point came when, over Moore’s objections, Greenpeace tried to ban chlorine, which is an element on the periodic table.

Moore laments, “the initial healthy skepticism hardened into a mindset that treats virtually all industrial use of chemicals with suspicion.”

That hardened mindset is The Certainty. It is environmentalism’s ugly side. It turns it into a religion.

We all know that religion can bring joy and comfort to people. But when The Certainty shows itself, religion becomes something darker.

The environmental movement is the same way. It is wonderful that activists have raised awareness. People prefer a clean environment to a dirty one, and sure enough, look at the data. Our environment is cleaner than it was fifty years ago. What a noble achievement.

Then The Certainty came in. Trying to ban this or that chemical without evidence of harm. Advocating technological regress. Attacking those with fact-based disagreements as corporate puppets, without ever touching the substance of their arguments.

There’s a reason why I think of (radical) environmentalism as the new religion. Like religion, environmentalism has done some good. But like religion, the more radical adherents have The Certainty. That can, quite literally, be bad for our health.

Astro Turf: Mankind’s Doom

Fields made of artificial turf are being investigated as health hazards because some of them contain lead. New Jersey has taken an early lead in overreacting by closing two fields.

This would be a cause for concern if there were signs of lead poisoning in people using the fields. But there is no evidence of even a single player getting lead poisoning.

It’s the dose that makes the poison. That dose just isn’t there in the fields.

A spokesman said, “In the 40 years that synthetic sports turf has been in use in the United States and around the world, not one person has ever reported any ill effects related to the material composition of the fibers.”

It really irks me when media outlets frighten people with scare stories like this. Now a government investigation is wasting peoples’ time and tax dollars because of it.

Blood Moon

There is a full lunar eclipse tonight. I was able to see it walking home from class. Turns out there’s also a view from my apartment’s balcony.

What a treat.

I’m a bit of an cosmology geek, something I picked up from my father over the years. One thing I noticed is that the eclipse really makes apparent the Earth’s larger diameter. As the Earth’s shadow was covering the moon, it didn’t look like the usual crescent moon; the demarcation between light and shadow had a much larger curve, almost to the point of being vertical.

Right now the eclipse is in totality, giving that famous “blood moon” red. It makes the moon look much more 3-D than usual. I don’t know the reason, but I suspect it has to do with interplay of light and shade. Instead of being totally illuminated or totally dark, the whole moon is faintly glowing. It makes the surface features easier to see, and also makes it look more like a sphere than a disc. Almost looks like it’s popping right out of the sky. Shame there won’t be another one until 2010.

Now if you’ll excuse me, I’m going to step outside and take another look.

Intelligent Design

Intelligent Design has become a trendy idea in the last few years. In short, it states that nature and life are simply too complex to have arisen spontaneously. A “designer,” i.e. God, simply has to exist.

How does anybody know that?

They don’t. Nobody does. Despite all of mankind’s achievements, we have yet to figure out the origins of life. Nobody is happy with this conclusion, so some people have simply made up answers to fill in the blanks.

That’s where every religion has gotten its unique creation story. That dissatisfaction is also the root of Intelligent Design. I want to know where we came from as much as anybody, but I’m afraid I just don’t know.

So let’s admit it. It’s not that hard. I know it’s not satisfying, but that’s the way it is.

There is a lot of excellent writing on Intelligent Design, especially by my fellow travellers at Reason. While they may be more eloquent than I, it’s frustrating that no one ever makes that single most persuasive argument: We don’t know. Accept it. It’s ok.
