MM: Now, the world has become closely connected more than at any other time of human history in many aspects. Economies are tightly linked, and an economical crisis like the Greek crisis in one country quickly affects many other world economies. Climate changes also influence the world. In the latter, a limitless desire of human exploitation of our environment has exacerbated these situations. A new viral infection quickly spreads within weeks like SARS. The HIV pandemic is a big tragedy to human, and avian influenza will be a new threat. To respond to these infections, we need a new platform of collaboration and friendship. Thus, we must appreciate that people and countries are indivisibly united. However, the sad thing is that people of the world are stuck in old thinking. We need to understand that in today's world it is not possible for one country to pursue mainly its own benefit.
