When my 7th grade vocational aptitude test came back stamped “Forester” instead of “Astronaut,” I knew the testmakers had screwed up. Sure, I liked sitting in streams and peering down those creepy holes by the roots of old trees. But I also knew that someday the whole frackin’ park would be flying through space. Hadn’t anyone else seen Battlestar Galactica?
Now we know that space colonists are just as likely to be muddy ecologists as hotshot flyboys, the kind of people who assemble ecosystems instead of engines. Today’s pack-it-in, pack-it-out life support is impractical for long manned missions, but in the future, regenerative systems could provide years’ worth of food, air, and water while processing human waste. It’s recycling and reuse on a radical scale, light years beyond anything pitched by those hairy guys down at the co-op.
Here’s a mini version of this dream, a sealed system biosphere that supplies a freshwater shrimp “econaut” with food, oxygen, and waste-processing for a desktop journey of 3 months or more, aka the Tabletop Shrimp Support Module (TSSM).
Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you?

Biosphere as decor, this is really cool! Do you have any photos from further along in the experiment?
That looks like eurasian milfoil in your biosphere in the lead photo. Perhaps a biologist could confirm. Folks should be aware that that is a terribly challenging invasive species currently choking many lakes in the northeast and should never be dumped in a lake or pond. It sounds like a fun idea otherwise!
