Small World

“The world is getting smaller..."

Yeah! The world is surely getting smaller and smaller. The total land area of the world is about 148,300,000 square kilometers, which still can be considered large enough for the current world's population (about 6 billion). However, due to the rapid population growth (special thanks to China and India and the United States), it is no wonder that it is running out of space. By the end of 2050, it is estimated that the world population will reach up to 9.5 billion although the land area will be almost the same. (Probably, the land area will be smaller as the sea-level is rising due to melting of ice-sheets in polar regions.)

Needless to say, even with the advanced technologies, the year 2010 will be facing serious problems such as global warming, declination of world's resources, population growth, shortage of food, energy and water sources and small world problem (a newly discovered problem). Therefore, many researchers are starting to hold that only space exploration and space colonization could save the world from extinction.

Space Colonization! Cool!!!

However, it is too expensive. Moreover, there is almost no one who wants to leave our beautiful earth and live on ugly-looking Mars. Due to its great expenditure, lack of volunteers and adventurers who want to live on other planets, and other inexplicable problems, researchers, scientists and world's learders are losing hope and trying to put an end to the space colonization project before they start the project.

With the failure of space colonization, it seems as if we were at the dead end. No, it is not. There is still an elixir for saving the world!
