There is a lot being written now (as always) about how humans should eat and what is the proper diet for our maximum health.  Nowadays all that is also being tied into what is good for the environment and the planet, since animal farming and agribusiness (read: corn) is such a big deal as well and all the topics are tied together.

I have read Michael Pollan’s books among others (including the Paleo Diet and Catching Fire: How Cooking Made Us Human), but I haven’t read the book discussed in the video below.  I have never been a vegan, although I did try vegetarianism for a while years ago.

I must say that I didn’t thrive on plant foods alone, even with eggs and milk products added in.  I feel much better when I eat plenty of animal flesh along with my vegetables as long as I keep wheat, corn, sugar and milk products to a minimum.  That’s hard, since they are everywhere, in everything, and yummy to boot.  I don’t have a zero-tolerance for them, but I don’t eat them at every meal, either.  It takes vigilance however.  Having them even once or twice can start me down a slippery slope toward having nothing but cake and ice cream at every meal and feeling like total crap all the time.

Anyway, even though I haven’t read The Vegetarian Myth yet, I thought the information and interview were interesting and wanted to share it with all of you.

My thoughts lately have been about Naturalism and what it means, both generally and to me personally.

Gull on a Rail

You never know what you'll see.

Naturalism in American Literature focuses on the tension between humans and the impersonal forces that act on our lives, such as heredity, environment, our passions and instincts, etc.

Naturalism in Painting involves merely depicting subjects realistically in a natural setting.

Naturalism in Philosophy is related to both of these, but seems to be much more broad.  It can include everything from a simple rejection of supernatural cause and effects to specific ontological or methodological doctrines, some of which are better labeled as scientism.

Meanwhile, a naturalist is a student of natural history and nature, and a naturist is a nudist.

Now, there’s nothing wrong with nudism…. but I’m not a nudist.  At least, I have no desire to be nude in public for any reason.  I like a layer of protection between my skin and the brambles, concrete, and insects out in the world.

However, I am a student of natural history, nature, philosophy, art, and literature.  And I do reject all claims to supernatural causes or effects.  And in my most recent fiction writing, I do explore the tension between the human desire for meaning and impersonal, indifferent universe.

So, I am a naturalist in all senses of the world.  I believe in Naturalism as a valid worldview, and I enjoy pondering the irony that we humans craving meaning despite living in a meaningless universe.

I believe we are happiest and healthiest when we live as naturally as possible while not giving up the sanitation or medical advances that our naturally evolved reason and quest for improvements has provided over the centuries.  I believe we should act in ways that promote the well-being of ourselves, our families, our society, and our planet, which includes (but isn’t limited to) conserving our natural, wild places.

But as in all things, doing this consistently is difficult.  It is even more difficult in our modern world filled with thousands of artificial distractions, temptations, and luxuries.  Balance is key.  It’s a good idea to use technology to promote the best things about our culture (education, tolerance, assistance, etc) without wasting time on the crap (most reality TV, sensationalism, fear-mongering, etc), and using that freed-up time to go outside once in a while.  Not for exercise.  Just for the joy of being out in the open air, walking among grass and trees, seeing the sky,  hearing the birds, feeding the squirrels, smelling the flowers or a fresh-cut lawn.

And walking from one building to another doesn’t count.  Really stop.  Look.  Listen.  Inhale.

Wouldn’t it be marvelous around the water cooler at the office if, instead of talking about the latest catfight on some stupid TV show the previous night, we spoke together about which flowers were currently blooming, which migrating birds were back from South America, and which which type of clouds are those out the window?

You may remember some time back I posted a Creature Feature blog about frogs because some new research had been published about the world’s tiniest frog.  Well, in the last couple weeks I’ve been reading newly published research about another new tiny creature:  the world’s smallest chameleon, the Brookesia micra.

World's Tiniest Chameleon

Of course after reading about that tiny little guy, I began to wonder what the world’s largest chameleon was. That would be the Furcifer oustaleti, measuring in at about 3′ long

Chameleons are best known for their ability to change colors, which is portrayed as a sort of ‘on purpose’ camouflage and that they can change to any color or pattern that is behind them.  But that’s not true.  According to this National Geographic article, out of the 100 or so species of chameleons, most can change from brown and green only, but only some can change almost any color, and it takes about 20 seconds.

Plus…. they don’t do it for camouflage.  It’s done in response to light and temperature and maybe even mood.  But it doesn’t seem to be a conscious effort to hide from danger.

Like my favorite group of birds, the woodpeckers, chameleons have zygodactyl feet, meaning they have two forward toes and two backward toes.  Also like the woodpeckers, they have extremely long tongues.  But the woodpeckers is only twice the length of its head.  The chameleon’s is twice the length of its body.

Unlike most  animals, I’ve always found chameleons to be particularly creepy.  It’s something to do with their googly eyes.  They can move each eye entirely independent of the other, giving them a 360° vision span.  (Humans have only about 120° vision span.)  They can also see in UV light as well as in our visible spectrum of light, as do most birds.

As a side note, “Karma Chameleon” by Culture Club came out in September 1983 and is still one of my favorite fun songs.

You can see at the top of the page that I’ve rearranged my tabs and added a couple new ones.  Under “Downloads” there is already one PDF available for colored pencil portrait artists.  There has been a lot of interest in my review of Kullberg’s Portrait book, so I hope my CP color chart is also helpful.  I have other things in progress to add soon, too.

Under “Art & Nature,” there’s a calendar listing Northern Virginia Art & Nature Events (it only extends to about 1 month into the future so far) and also a listing of Northern Virginia places to go birding, wildlife watching, and plein air painting.  I’ll be adding to both of those as time goes by, too, including my reviews of those places, and eventually a map of all the locations.

So enjoy these new features and leave a comment below if there’s anything specific you’d like me to add.

Squirrels are mammals in the order Rodentia, the same as not only mice and rats, but also porcupines, beavers, capybara, and dormice.  All in all, there are over 2000 species of rodents.

The defining feature that unifies the order Rodentia is that their front teeth grow continually and have to be worn down by near-continuous gnawing. If they didn’t gnaw, their front teeth would grow until digging into some other part of the face or mouth and disable or killing the animal.

Squirrels live on every continent except Australia and come in 200 species.  Our most common squirrel around Northern Virginia is the Eastern Gray squirrel (Sciurus carolinensis). However, there is another species that lives here: the Black Squirrel.

The first time I saw a black squirrel, I did a double-take. I hadn’t known there was such a thing. I looked it up first chance I got. Apparently they were brought to the DC area from Canada in the early 1900s and the population survived.

I like squirrels as much as any other animal. Until they raid my birdfeeders. Most of my feeders are squirrel-proof, but I still end up feeding them since birds aren’t the neatest eaters and some feed ends up on the ground.

When I can count seven or more squirrels in my yard at once, even I might think all squirrels should die. I joke around around buying a bee-bee gun and having squirrel stew for dinner, but that won’t ever happen.

But if I saw one of these purple squirrels, I’d wouldn’t be running for my gun. I’d be running for my camera.
