Stasis and Change in Left-Wing Politics and the Environment

The discussion in my last post about how the political left advocates change of every sort yet appears terrified of any change in the environment – or has adopted such a pose, at any rate – left the environmental portion for another day.
The quick and easy hit about refusing to “embrace change” in this one important area struck me as pointing to an important idea. Why do certain people think the environment should remain exactly as it was, when nature continually provides evidence of its (or, as another era would have put it, “her”) ability to produce unpredictable events and inflict cataclysm at every turn?

Some conservatives attempt to explain the fundamental weirdness of so many liberal or progressive policy prescriptions – especially on the environment – as flowing from the increasing disconnect of urban residents from the natural world. That seems to have merit. But this view is undermined by two things: first is the ubiquity of information media that bring nature’s acts – tsunamis, volcanic eruptions, earthquakes killing tens of thousands – into the home or office, second is the burgeoning popularity of recreation out in the natural world, made possible by the very mass prosperity and personal mobility the left opposes. Nature’s real nature is on display before you, if you’re willing to look. Many appear unwilling.

One example in this vein would be the manic environmental controls imposed on mining or other resource companies when conducting previously innocuous activities such as bridging a stream. Nowadays such supporting projects often impose years of study and regulatory process over fears of erosion and the allegedly ruinous effects on fish and their habitat. Imperial Oil’s Kearl oil sands project was recently thrown off the rails over a water-related issue of this sort. Meanwhile a few days of spring rains send our local rivers to 10 or 20 times their normal flows. Raging above their banks, the waters strip away thousands (perhaps millions) of tons of topsoil and snap stands of trees like so much matchwood. But hey, at least that’s natural.



Ice Cream in a Can, Teaching Science

Educationb{Originally published on SusieJ}

This summer, our hill at the lake will be used in yet another ingenious way: to make ice cream for our root beer floats. I was tempted to buy the traditional ice cream maker, but there are so many choices; I quickly became overwhelmed looking at all the bells and whistles. And besides, I have all that boy power just dying to get put to use. Plus, the process of making ice cream by hand… literally…. in the can… is is a great way to introduce some lessons in science. There is the ice cream in a bag method; my boys would surely break the bag in the mixing process. So, I’ve decided to go with the ice cream in a can method.

  1. The first challenge is finding the can. Many recipes suggest using
    a coffee can, but who buys coffee in a can anymore? A better idea is
    to ask for an empty paint can from the paint store. You’ll need two: A
    quart, and a gallon.
  2. Ask your kids to tell you the freezing point of water — or teach
    them — 32 degrees F, or 0 Celcius. Then, ask them what happens when we
    put salt on icy sidewalks. Ask them to start thinking about why we need
    salt to make ice cream.
  3. In the small, clean can, add one cup of milk or half and half, one cup of sugar, and one teaspoon of vanilla.
  4. Optional: add one tablespoon of chocolate syrup — or frozen strawberries.
  5. Use a hammer to seal the lid tightly.
  6. In the larger can, combine the ice and rock salt. Use a thermometer to record the temperature of the rock and salt mixture.
  7. Use hammer again to seal the lid tightly.
  8. Take turns rolling the can down the hill, for about five minutes. This will “solidify” the ice cream.
  9. Explain what’s happening: the ice melts and combines with the salt.
    This “brine” has a lower freezing point — lower than 32 degrees.
  10. After five minutes of rolling, open the large can, and take the
    temperature of the ice. It will be colder than it was the first time.
  11. Open the smaller can. The colder brine was able to get the milk
    mixture cold enough to freeze the milk mixture to make it solid, to
    create ice cream.
  12. You know you’re going to have to whip up another batch right now; the fun was really rolling the can down the hill.


Killing Fairies

Family

One of the most important responsibilities
- nay, obligations – of any parent is, I think, to encourage our children’s
daily awareness of all that is magical and mysterious in our great,
big fantastical world.

And, yes, I am a hippie.

To point our children toward a sly glimpse of the crystalline fairies
in a drop of dew….

To wonder in awe at Titan voices booming across the evening sky during
a summer thunderstorm….

To marvel at orchestras captured on silver discs, musicians trapped
like microscopic genies to be released in song only at the listener’s
wish and command….

Ah bliss! Ah joy!

To support and stimulate their creative selves and thusly nourish their
hearts and souls with the food of poets and saints!

(And I’m not talking cigarettes and day-old baguettes.)

But, as a bittersweet fact of life, every day my children grow a bit
older and, so too, a bit too wise for the world’s magic.

Mostly, I blame science.
