  2. Re:Paper versus Plastic? on Swedes Say Recycling Wastes Time And Money · · Score: 2, Informative

    When you look at all the angles, the problem can seem overbearing, but gestalt for a minute. Mainly, the issue is "we use x tons of stuff and produce y tons of waste". Reduce x and y automatically goes down. Food packaging is just one example of riotus overuse. The fact that so many items are individually packaged is just ridiculous! I can make 4 containers to hold 500ml of liquid but use less resources if I package all 2000ml in one package. This is basic geometry. And so much that we produce doesn't recycle easily or is toxic to living organisms. What to do with waste "y" is a difficult question and I'm not sure what the best solution is, but certainly using less product "x" makes the problem smaller in range and scope.

    Yes, every method for dealing with waste does cost something. Using less in the first place and reusing whenever possible makes this problem less daunting. Maybe consumption could be reduced to such a point that the amount of waste could be effectively (both environmentally and econimcally) dealt with.

  4. Whew... on Gaiman's American Gods Wins Hugo · · Score: 2

    ...who would have thought that so much posting and controversy would be stirred up by this! For the record:

    1) I liked American Gods very much when I read it and even felt it was a sort of commentary about current american values. 'Course, I love everything Gaiman has ever written including Sandman, Neverwhere, Good Omens, and so forth.

    2) I thoroughly enjoyed Goblet of Fire and all of the other Harry Potter books. They are mere mind candy (not difficult reading) and enjoyable for what they are.

    3) Should a Harry Potter book have recieved the Hugo? Well it is good writing for what it is. But in the rampant discussion concerning what is fantasy and what is sci-fi, there are many grey lines. That being said, I believe that Harry Potter is purely fantasy. And if the Hugo is a sci-fi award, then it shouldn't have been awarded to Goblet of Fire. Gaiman's works tend to fall in the grey area and are even similar to the "urban fantasy" works of Charles DeLint. I don't think that I would give DeLint an award in the sci-fi category (even though I really love his stuff and recommend it to everyone) but surely in the fantasy realm. Maybe American Gods should be in that realm too. Then again, I really like Gaiman's work, and since it is in that grey area (an area that theoretical physics is in as well) I'd just as soon not argue at length as to whether it deserves the Hugo or not. Let's just say that I'm glad it got an award.

    4) Finally, there are way too many posts under the "Narrow Minded Bigot" subject that are just way off-topic but have been modded up for being "insightful" or similar. People debating what is christian/pagan etc. (though very politely in general, thank-you) is not on the topic of this years and last years Hugo award winner.

It would be nice to think that they could (or perhaps even are sometimes) achieve all the results that the CTV article claims. This would seem to call for a fairly full investigation of what sort of equipment could be designed to be more reliable and what kind of results could be consistently achieved.

    O.K., the word on mushrooms (and other fungii) is this: They are REALLY hard to grow in a casual/won't-be-there-on-the-weekend/or-that-week- I-go-away environment. What's more, the mushroom as we think of it is only the fruiting body of a plant that is basically never seen. A mushroom is generally a mass of white threads in the soil, at the base of a tree or under the bark of a rotting tree (depending on what kind of mushroom it is). There is nothing to see except for when the mushroom decides to produce fruiting bodies to distribute spores (which it will do only when it thinks conditions are PERFECT). Some mushrooms have little or no smell, or they smell "earthy." Others stink strongly. And while there are many kinds of edible mushrooms, there are others that, if accidentally ingested, whill kill you in a terrible and painful manner (like total shut down of the liver or complete destruction of the nervous system). I know this because I hunt wild mushrooms to eat. And almost all of them do NOT grow in sh*t. Very few do. One of the many nuances of growing them is getting the right combination of soil and moisture and keeping your culture sterile and pure which is very difficult.

    I've only managed to grow one mushroom indoors and that is one that grows in a pot with a type of shamrock. I didn't even try to plant it. It just appeared! It is the only mushroom I know of to commonly appear in houseplants (the lemon-yellow lepiota or Lepiota Lutea) and is poionous if ingested. So while "mushrooms" is an amusing answer to your query, it is in no way practical at all.

    And yes, it is "technically" a plant, part of a major division of the plant kingdom known as "non-flowering" plants which includes hornwarts, lichens, mosses, some palms and evergreen trees.

    ...I recommend spider plants. You just stick them in some water and they grow just fine, they don't even need soil. You can buy one potted for pretty cheap at any home center (you can probably get one for around $1.99). When it forms runners, you can cut them off and place the leaf clusters in water and they *will thrive*! You can also try to find a friend who already has a spider plant and get clippings from them. Once the cluster has developed a root system, you can then pot it in soil or leave it in water, either way! I've had one spider plant for 15 years. I don't know how many years my mother had it before that. I've rooted many plants off of it too. You can let potted spider plants dry out even. They'll start to look like they need some water but will survive this way for a l-o-n-g time. Just give them some water and they bounce right back! If you water them regularly, they get downright jungle on you. They can do well in everything from direct sunlight to very little light at all. This will affect how deep a green they are (along with water) and will also determine whether or not they form yellow colored veins. These are truly hardy plants. The only way I know of to kill them is to let one (not in soil) dry out for a few weeks, or, let one (in soil) dry out for over a month. I've never fertilized one, ever, just watered. Sometimes I put the dead leaf clippings back into the pot. If you want, you can put them under a grow light. If they get enough light, they will produce runners with very small white flowers (they don't really have any odor that you would notice). These are really great plants and they produce some great oxygen! So grab a spider and get growing!

Manure is biodegradable and its excess runoff has done a fine job of screwing up the Chesapeake Bay (just to name one of a multitude of places).

Whereas other things that we want to do (like brushing your teeth) or don't want to do (like quitting smoking) do not themselves generate closely time linked positive responses. The benefits of these activities is apparent over time but there is no immediate dopamine response related to either. When you are trying to quit smoking, You dopamine levels probably decrease every time you deny yourself the "burning pleasure". It is through a strong consistent act of consciousness (exertion of will), or a minor superiority complex (I'm better by doing this thing and thinking that I'm better actually gives me a dopamine dose), or an outside dopamine reducer/raiser (if I shock myself when I smoke/reward myself with sugar when I don't I'll forcibly change my behavior.).

The inner sections grow older and eventually die off, but the younger surrounding sprouts survive and continue to sprout outwards themselves. Scientists can take any preserved samples they can find of the older dead parts from the center and find out when the bush started growing (or at least measure the minimum of how old the bush is since even older parts may have completely disappeared with age).

    Because of the wind conditions of where this particular bush is growing, only the sprouts on the leeward side have survived and continued to propagate. Scientists searched in a line windward from the bush and followed the trace root remains as far as they could to find the oldest parts. These dead remains of an earlier part of the bush are what they are carbon dating.
