Soon, you too will be able to make your own whatchamacallit right from your printer

I heard a story on NPR this morning about the falling price of 3-D printers and scanners and copyright issues.
Does anyone really think that Disney, et. al. won’t have an issue with people making their own plastic princess or Star Wars character?

I heard another version a week or so ago about the possibility of making a functioning gun with such a 3-D printer. The consensus was that at least at this point, no gun made in such a way would work.
The tack the companies making these printers and scanners take is how wonderful it would be for everyone to make their own version of things to save money or design them the way they want.
But nowhere have I heard anyone discuss the environmental side of this. First there’s the do-we-really-need-more-stuff issue, and then there’s the matter of of making your own whatever out of molten plastic.
Basically, with one of these printers, you scan the picture of the image you want to make, put it in the printer and it turns it into a 3-D image that is then laid down in hot plastic a few microns at a time.
In a few hours, ta da, you have your very own whatchamacallit, possibly for a fraction of the cost of going out and buying the real thing, which might or might  not be made of plastic.
And I’m guessing it’s not plant-based plastics steaming out of your $2,000 printer.
So there are likely to be chemicals steaming out and off-putting from your kid’s new toy.
The technology side of it is fascinating, I grant that. But really, do we need more plastic stuff?

The story of a dog, a dead rabbit and a plastic bag

We did a little science experiment in our yard, unexpectedly, thanks to the laws of nature and survival of the fittest a while back that we came across last week.

A little background:

About a year ago, our aging dog managed to kill a rabbit and eat about half of it before my husband called her off it.

He brought her in the house, where she promptly threw up, right in front of the fridge and my daughter.

As she stood over the steaming pile of blood, bone and guts exclaiming “eeeww” repeatedly, my husband swore, then cleaned up the mess and buried the remains (including the part the dog didn’t eat that was still in the back yard) in a plastic grocery bag behind our shed. He marked the spot so we would know where it was.

Fast-forward a year.

While digging a new compost area last week, he dug up the bag that had contained the remains of the rabbit. Guess what?

The rabbit was gone, completely decomposed and turned to dust.

And the bag?

Completely intact. And I mean completely intact. It had decayed not one little bit.

So please, ponder that the next time you’re in the grocery store or anywhere else they are likely to give you a plastic bag. That bag, which took chemicals to create, will be around for a very, very long time.

Our Plastic Nightmare, Now on Video

A 5-minute video shows the effects of plastics on the planet, from drilling oil and how plastics are produced to the littered bottles and plastic bags strewn along roadways and beaches, in the oceans and mountains, to the detriment of fish and animals alike.

Watch it here, from the Wild Green blog on UTNE Reader: Our Plastic Nightmare, Now on Video. How does it affect you? Will you stop and think about it the next time you are buying a bottle of water?

How many human-made products can you name that don’t contain any plastic in the product or the packaging or both?

Can you, or will you, stop buying things that contain plastic?

That’s going to be much harder for all of us, isn’t it?
