From the article

"Moreover, a complete end to imports would actually hurt the U.S. economy, because consumers and domestic companies would lose access to cheap goods."

"But financial experts say that it's best for America if you buy the cheapest product you can find without sacrificing quality. Their explanation rests on the concept of efficient manufacturing. An efficient producer creates the most valuable goods with the least possible expense, selling those items at lower prices than competitors who are less efficient. A country benefits when its manufacturers become more efficient."

My opinion: I think this article's treatment of the issue (Buying goods made in the US) is somewhat superficial, but it does highlight some counterpoints that seem rarely to be mentioned.

20-foot URBAN FARMS : Compact, Versatile, Aquaponic Systems

2012-06-17T20:23:00.005-07:00

Using standard ISO shipping containers and twenty foot long greenhouse you could have a tiny urban farm capable of feeding several families. By integrating the greenhouse with aquaponics and anerobic digesters a closed loop system with relatively good energy efficiency is able to placed almost anywhere.

From the article

The patented technology can increase normal yields by 20 times and only requires 8% of the water used in conventional field farming.

This type of technology improves local accessibility to healthy foods, especially in urban environments where the ability to grow such foods is often constrained.

Fiscal reform: Why we're hosed (Short Article)

2011-09-12T10:59:00.000-07:00

Image from fitfinity.net

From the article:

For many years it has been painfully apparent to anyone who cares to face facts that entitlement spending, especially on health care, is on a growth path that will eventually require enormous tax increases to sustain. Yet thus far, any efforts to either restructure entitlements or raise the taxes needed to pay for them have run into a buzz saw of hostility from the electorate.

There seems to be some kind of widespread delusion that a small tax increase on the rich, combined with cuts in not-very-important spending categories will somehow deliver us from fiscal ruin. There is little appetite for the cuts in military and entitlement spending necessary to bring America's books toward balance.

From the article:

Researchers in Wisconsin have designed a sneaker insole that captures the electricity generated by the walker’s steps, reports Mother Nature Network.

Right now, Krupenking and Taylor are estimating between 1 and 10 watts.

The researchers say that no direct physical connection is required to bridge the insole and the wireless device.

Got Toxins in Your Home? Get Ferns. (Short Article)

2011-08-26T06:57:00.000-07:00

Picture from http://kuriles1.ru/img/gallery/27.jpg

From the article:

Indoor volatile organic compounds (VOCs) such as formaldehyde can contribute to allergies, asthma, headaches, and so-called “sick building syndrome”.

The World Health Organization estimates that toxic indoor VOCs represent a serious health problem that’s responsible for more than 1.6 million deaths annually … and a shocking 2.7 percent of the “global burden of disease”. (Commentary: I find these numbers a little hard to believe)

Now, a team of scientists from South Korea and the University of Georgia have ranked 86 plants in order of effectiveness at removing volatile formaldehyde from indoor air (Kim KJ et al. 2010).

Lead author Kwang Jin Kim cited the benefits: “It is evident from our results that certain species have the potential to improve interior environments and, in so doing, the health and well-being of the inhabitants.”

Abstract from the original paper (a little too sciency for most?):

The efficiency of volatile formaldehyde removal was assessed in 86 species of plants representing five general classes (ferns, woody foliage plants, herbaceous foliage plants, Korean native plants, and herbs). Phytoremediation potential was assessed by exposing the plants to gaseous formaldehyde (2.0 μL·L^―1) in airtight chambers (1.0 m³) constructed of inert materials and measuring the rate of removal. Osmunda japonica, Selaginella tamariscina, Davallia mariesii, Polypodium formosanum, Psidium guajava, Lavandula spp., Pteris dispar, Pteris multifida, and Pelargonium spp. were the most effective species tested, removing more than 1.87 μg·m^―3·cm^―2 over 5 h. Ferns had the highest formaldehyde removal efficiency of the classes of plants tested with O. japonica the most effective of the 86 species (i.e., 6.64 μg·m^―3·cm^―2 leaf area over 5 h). The most effective species in individual classes were: ferns—Osmunda japonica, Selaginella tamariscina, and Davallia mariesii; woody foliage plants—Psidium guajava, Rhapis excels, and Zamia pumila; herbaceous foliage plants—Chlorophytum bichetii, Dieffenbachia 'Marianne', Tillandsia cyanea, and Anthurium andraeanum; Korean native plants—Nandina domestica; and herbs—Lavandula spp., Pelargonium spp., and Rosmarinus officinalis. The species were separated into three general groups based on their formaldehyde removal efficiency: excellent (greater than 1.2 μg·m^―3 formaldehyde per cm² of leaf area over 5 h), intermediate (1.2 or less to 0.6), and poor (less than 0.6). Species classified as excellent are considered viable phytoremediation candidates for homes and offices where volatile formaldehyde is a concern.

Hidden Hunger: How much can farming really improve people's health (Short Article)

2011-08-24T10:22:00.000-07:00

http://www.economist.com/node/18438289

From the article:

In 2008 the Copenhagen Business School asked eight eminent economists to imagine they had $75 billion to spend on causes that would most help the world. Five of their top ten involved nutrition: vitamin supplements for children, adding zinc and iodine to salt and breeding extra micronutrients into crops (like those sweet potatoes). Others included girls’ schools and trade liberalisation.

The missing nutrients bite wide and deep. Education levels drop (malnourished children concentrate poorly); earning-power weakens. Even marriage chances wane: malnourished boys marry women of lower educational levels when they grow up.

The success stories are instructive. In 1990 a charitable organisation called Helen Keller International started to encourage market gardens in Bangladesh, providing women (mostly) with seeds and advice. By 2003 (the year of the latest available research), four-fifths of families in the target area had gardens, against 15% in the whole country. Almost all women and children were eating green vegetables three times a week, compared with only a third beforehand. And vitamin A intake had soared. Projects like this work because they improve what people like to eat anyway.

Policymakers can also try to increase women’s control over farming decisions (in some countries, only men may own land or get agricultural credit, for instance). They could boost research into more nutritious non-staple crops; and provide clean water and better transport, which especially benefits kitchen gardeners, because their produce goes off.

UK riots: What turns people into looters? (BBC News)

2011-08-16T07:23:00.000-07:00

http://www.bbc.co.uk/news/magazine-14463452

From the article:

Numbers are all important in a riot and the tipping point comes when the rioters feel in control, he adds.
"You cannot riot on your own. A one-man riot is a tantrum. At some point the bigger crowds confronting the police realise that they are in control."

"Humans are the best on the planet at imitating. And we tend to imitate what is successful. If you see that people are walking out of a shop with a widescreen TV and trainers, a certain kind of person thinks why shouldn't I do that?"

Workman argues that some of those taking part may adopt an ad hoc moral code in their minds - "these rich people have things I don't have so it's only right that I take it".

For most, the motivation is the thrill, with the "free stuff" just a bonus. But not for the ringleaders who manipulate the mob to target high-value shops.

"If you compare it to the riots in the 1980s, there's a lot more stuff you can loot easily, such as portable electronic gadgets, mobile phones and flatscreen TVs.

Nature Objectively Aids Healing (Article)

2011-08-13T10:12:00.000-07:00

From the article:

“… post-surgery patients resting in rooms overlooking trees recovered better and faster than those in rooms with a view only of a brick wall … [and] women with breast cancer who walked in a park, watched birds or tended gardens recovered more quickly and were in better spirits than those with little or no contact with the natural world.” (McKinney J 2011)

Three years ago, University of Michigan scientists reported on two “experiments that show that walking in nature or viewing pictures of nature can improve directed-attention abilities … thus validating attention restoration theory.” (Berman MG et al. 2008)

Encouragingly, those who had the most stress reported the greatest relief from time in relatively untamed nature.

However, those who needed nature the most were the least likely to seek it out:

“the more worries about money and work a person had, the more stressed a person had felt during the last year, the less energetic s/he had felt, the lower was the number of visits to the favorite place (during the last 6 months) and the lower the typical level of restorative experiences.”
