 Mapping Tree Density at a Global Scale
An article entitled “Mapping Tree Density at a Global Scale” appeared in the journal “Nature” this month discussing the tree density worldwide [l]. One figure showing tree density is striking:
In the latter, the white dots represent areas with year-round ice cover, the brown dots represent areas with no trees, while the dark green dots represent areas with the highest tree concentration. The land proportion composed of areas with little or no trees is alarmingly large — about half of the world's forests have been destroyed or irremediably damaged since the advent of agriculture 10000 years ago. But what is more worrisome is that half of this destruction took place in the last 50 years.. Still today, it seems we haven't learned our lesson: we continue to cut down more trees than we plant as we have been doing for generations. If we do not change our living habits soon and start caring for our environment, the entire planet will be treeless within a couple of centuries.

The website worldbusinessculture.com [l] gives information on how local culture can affect meetings, communication styles, management styles, etc. This can be useful in understanding foreign cultures obviously but also in not making a faux pas when visiting foreign firms/universities or when collaborating with them. The information seems spot on, at least regarding the countries I have experienced firsthand (Japan, South Korea, Canada, U.S.).

 Steve Jobs Commencement Speech: Linking the Dots
Yesterday was graduation day at Pusan National University, and this reminded me of an inspiring commencement speech I had seen on youtube a while back. One part that I particularly liked is the one about “linking the dots”, with the dots referring to ideas or concepts. Many ideas we get, many papers we publish as researchers may seem useless at first. But often, the breakthroughs that are useful to society come from linking together these seemingly useless concepts. Sadly, linking the dots is becoming rarer these days in university environments. Less and less focus is now given to long-term basic research (i.e. the seemingly “useless” research) and more and more emphasis is given to short-term research with immediate applications. Ironically, putting emphasis on research that is immediately useful prevents more useful breakthroughs from occurring..
