One of the most serious and, in many cases now unpredictable, risks facing investors is “country risk” – where the political and economic stability of the host country is questionable and abrupt changes in the business environment could adversely affect profits or the value of the company’s assets.

Let’s never forget, in our rush for profit, that there is a real human cost involved.

These are not written by me, but a merciless capitalist.

… Model builders seem to assume implicitly that passing on knowledge, which was acquired through scientific research, is sufficient to convince people to change organizational policies. Studies on the impact of computer models on policy making have convincingly revealed two things. First, in most cases the impact is conceptual (i.e., people learn from it), rather than instrumental. Second, most of the learning takes place in the process of building the model, rather than after the model is finished.

first paragraph of this Foreword twelve years ago.

While global warming is the hottest point of carbon dioxide emission reduction debate, ocean acidification seems to be forgotten. The deniers (not skeptics) generally agree that carbon dioxide emission is growing exponentially (may be they cannot deny due to Keeling Curve), what they argue is the link between carbon dioxide and global warming. OK, let’s say no global warming, how about ocean acidification?

The increase of carbon dioxide have changed the composition of carbon on the earth, especially the exponential growth means change rapidly. What is the potential impact of the change? Every action have consequence.

I am no saying we should not take any action. Change is the only constant of the world. But we should be careful, especially if the change is fast. We should think about its possible unintended consequences, whether it is tolerable or not. Global warming catches the most attention because of its high hazard, but even without it does not mean carbon dioxide emission is fine to grow. This great change of carbon cycle must affect us, since everything in the world are interconnected.
