Why IPv4 Addresses Are Like Oil

IPv4 addresses are an increasingly rare resource. But I'd not spotted the parallel with oil until this:

the US was still the largest user of new IPv4 addresses in 2008 with 50.08 million addresses used. China was a close second with 46.5 million new addresses last year, an increase of 34 percent.

Although China and Brazil saw huge increases in their address use, suggesting that the developing world is demanding a bigger part of the pie while IPv4 addresses last, what's really going on is more complex. India is still stuck in 18th place between the Netherlands and Sweden at 18.06 million addresses—only a tenth of what China has. And Canada, the UK, and France saw little or no increase in their numbers of addresses, while similar countries like Germany, Korea, and Italy saw double-digit percentage increases.

A possible explanation could be that the big player(s) in some countries are executing a "run on the bank" and trying to get IPv4 addresses while the getting is good, while those in other countries are working on more NAT (Network Address Translation) and other address conservation techniques in anticipation of the depletion of the IPv4 address reserves a few years from now.

In other words, the greediest countries - the US and China - are rushing to burn up all the oil while there's some left, and to hell with what happens afterwards....

Ecological Economics and the Commons

Heavy but important stuff here:

some resources should be part of the commons because their physical attributes mean that common ownership and democratic allocation will be more sustainable, just and efficient than private ownership and market allocation. Information, which will play a critical role in solving the serious ecological problems we currently face, is one of those resources. So too are most ecosystem services. The fact is that conventional markets based on private property rights do not work to solve the macro-allocation problem, which in recent decades has become far more important than the micro-allocation problem. Solving this problem instead requires a system based on common property rights and democratic decision making concerning the desirable provision of ecosystem services.

Virtual Water

If you thirst for new ideas, try this:

Virtual water is the amount of water that is embedded in food or other products needed for its production. For example, to produce one kilogram of wheat we need about 1,000 litres of water, i.e. the virtual water of this kilogram of wheat is 1,000 litres. For meat, we need about five to ten times more.

The per capita consumption of virtual water contained in our diets varies according to the type of diets, from 1m3/day for a survival diet, to 2.6m3/day for a vegetarian diet and over 5m3 for a USA style meat based diet.
