Life Cycle Analysis

This NPR piece, Sizing Up Your Green Footprint, is about how to buy consumer products with smaller carbon footprints. The example they use is reading books on an Ipad rather than buying actual books. It may seem better to use an Ipad, but when factoring in all the costs of actually making the Ipad, you'd have to read a lot of e-books before you come out ahead.

I liked this comment, though.

When comparing the costs of books and Ipad, I’m curious if Daniel has factored in the cost of building, insuring, heating, cooling, carpeting, etc… of all the space needed for books and libraries over a period of the life of each book. I’m also curious if he has factored in the transportation of books now, and the several other instances they will change hands in the future? Also, the Ipad isn’t just a book, it also does what many computers do, but with less weight, and I’m guessing, with less energy. A better comparison would probably be with a digital reader using digital paper.

Another thing is that it's hard to compare unlike things. When calculating ecological impact of products we try to put a number on things, whether it be carbon or dollars. However, it may be that cutting down trees for virgin pulp causes more damage than just the carbon sequestration lost. A major challenge is doing analysis with different units.

Sell Short

Interesting piece from WBUR on some novels about the financial crisis by Michael Lewis like the Big Short.

Burry figured that he could bet against pools of these subprime mortgage loans using an instrument called a "credit default swap," essentially insurance on a corporate loan. Burry persuaded the investment banks to create credit default swaps for the subprime mortgage market.

"As the pools of loans that are underneath these bonds start to default," Lewis says, the investment banks that gambled on the subprime mortgage loans were forced to send Burry money daily as the bonds went bad. "Wall Street firms, they were on the other side of the bets."


And in the clip, they talk about how AIG was where the Wall Street firms got their money.

Time Banking Community

I heard a really interesting story about time banking today. It is like bartering, but instead of directly exchanging goods, you provide services and you log how much time you spend, and then you can redeem them for other people's services.

triangle

from npr

the interview is pretty great, with quotes such as

"Triangles have been important to mankind for a long time, ever since Pythagoras and the great pyramids, and cave paintings have triangles on them," Justus says. "Triangles are a big part of our humanity and our culture."

Race

On NPR today, they were talking about how France is racist, and yesterday they were talking about how Germany is racist. They said that part of why France is racist is that ever since their African colonies became independent, they feel that black people are ungrateful. Honestly, that is probably how Chinese people would feel if Tibet became independent. Many Chinese people already feel Tibetans are ungrateful for all the money that is spent on them, although Tibetans feel that the people benefiting the most from these development projects are Chinese businessmen. Anyway, they said that Germany is racist because they've always placed a value on the exclusivity of being German so there are some immigrants there who have been there for three generations and Germans don't think they are German. On the one hand, they are not German, ethnically, but nationality isn't the same as ethnicity anymore. Germany apparently only recently made it possible for people who are not ethnically German to obtain German citizenship. This sort of surprises me that a modern developed Western nation would do that, although I supposed Iceland is like that, too. These tensions always happen when the demographics change drastically. Like right now, Chinese society is pretty homogenous, and so most Chinese people also think that you are not Chinese unless you look Chinese, and for the most part, they are right since China was not open to the West until the 80s. The difference, though, is that Chinese people have adopted Western attitudes towards race. That is, white people are rich and to be respected whereas black people are looked down upon a little. Many foreign white people still feel offended that they are considered outsiders even though some have lived there longer than people like me, haha. But I think they are overreacting. If you can't speak Chinese and are second generation, for example, Chinese people also consider you an outsider, and these white people grew up in the US or UK. Of course no matter how well you speak, if you've lived most of your life outside China, especially your formative years, you are culturally not Chinese. And even though I grew up in the US, it's not like I was adopted and raised by white people. Regarding black people, the central government occasionally tries to ease tensions by having Africa expos or having a black person perform at Chinese new year's, and it certainly helps to a certain extent. Anyway, I found the discussions about the roots of racism in the different countries pretty interesting.
