I suppose you also may not like to eat sugar from sugarcane or sugar beets that has been drenched in insecticides? I suppose you could eat Splenda.

So, I'm not really sure why a posting on sugar beets makes it onto /. anyway, but I'll cast in a couple important points for civil discussion. 1) The pollen from sugar beets does travel a very long distance (Darmency, H. et al., 2009. Pollen dispersal in sugar beet production fields. TAG Theoretical and Applied Genetics, 118(6), 1083-1092). 2) This is may be an environmental concern, but it is also a concern for anyone growing sugar beets. That is, there are problems controlling weedy beets when herbicide-resistant beets sprout up. 3) This entire issue is unimportant when beet growers cultivate off the tops of their beets, rendering them sterile. If they receive a higher yield for the herbicide usage, this may be an extra drive across the field may be a good option for preserving the integrity of the resistance trait.

You mean, other than logging, mink farming, and fly breeding.

Get the acronym right! It's Iowa!

Look it up (and maybe read the article too). There is usually a considerable amount of evidence that goes along with these axes that makes them much more likely to be tools than the result of geologic processes. This particular item was collected from a a site that has a history of producing items from an ancient culture. Yes, there are stones out there sharp enough to be useful (e.g., naturally broken pieces of obsidian). The point isn't that they are useful, but that they have been used. Some tools are made and some are found.

Upon further reflection, and with your succinct description, I think I understand. Obviously, stereoscopic view isn't needed to track orbits, most telescopes are monocular. One just needs to see something moving (e.g., a tool-bag in orbit). I guess for some reason the impression of an object heading straight at the lens came to mind, which is clearly, well silly.
