Why should we care about what happens in places far away from where we live?

We should care about what happens in other places, as our country is dependent on other countries for nearly everything, like food, economy and others. We have to import food from other countries like Thailand, and if a disaster happens there, our reserve food store cannot last for very long, and thus if that happens, we then have to prepare immediately for that.
Also, Singapore is lacking in land area, raw materials and consumers. Therefore, we need to invest in other countries for land, import raw materials into Singapore, and export those raw materials as products to other countries.Thus, Singapore is heavily reliant on other countries. If anything happens to these countries, Singapore would be badly affected, and our economy might fall, thus creating a bad situation for Singaporeans.
 Also, for incidents such as natural disasters, we can send help to that country immediately, both to
fulfill our moral duty and to show off our military power to other countries, killing two birds with one stone.
It is also important to get a knowledge of the current affairs, to improve ourselves and be up to date with the world. Also, we have to get a better understanding of the world, so that we can learn from the situations in other countries. For example, for Japan's nuclear scare, we can use it to think through whether Singapore should use nuclear power for electricity. Also, if there are beneficial situations in other countries, we may be able to apply the situation in Singapore if it can help.
