Do it!

As an FYI, if you want to see this same data with a linear scale, go to http://www.gapminder.org/world. By default, the x-axis has a logarithmic scale but can be changed to a linear one. Also, the data points can be changed per axis (for example, income per person on the x-axis can be changed to children per woman).

In terms of efficiency, it would be most efficient environmentally to have N. Koreans consume protein-rich vegetables directly, as each step through the food chain is about 10% efficient. This is why, if you look down the food chain, the biomass of plants and vegetables is exponentially greater than herbivores, as herbivores are exponentially greater than carnivores. At each step down the line, there is a tremendous waste of energy.
