However, our growth has some cause for concern. Our growth created the need for good and services at an astronomical level. The solution to this problem was creation of industry where massive factories and plants pump out a variety of good for us to consume, but all this development to sustain ourselves has slowly taken up the land on which we live on. Countries like Japan where industry and technology are the crowning achievements of their society, land is scarce and cities are overflowing with people. .
Earth contains a limited amount of natural resources which human beings need to keep there standard and progressive lifestyle. There will be a time when we will have exhausted all of the earth's resources. That is why the next logical step is for human beings to again expand their boundaries to find other useable resources. The vastness of space holds the key to the future of the human species. Our expansion into space is inevitable as the resources of earth run dry and with the eventual overpopulation of earth the human species will have to colonize other planets to suit and their needs and development. Objects such as asteroids, comets, lunar planets and martian planets hold a lot of useable and much needed materials, such as ice, which can be melted into water which is essential for any living organism. They also contain precious and non-precious metals and possibly undiscovered elements. What's more exciting is we will be able to find new energy sources. We could tap the suns powerful solar rays for energy with giant satellite solar panels; they would continuously be obtaining trillawatts of energy. Imagine unlimited and cheap electricity for everyone! That would hold a tremendous global impact, especially since its clean energy. We would be able to develop the entire undeveloped world, making everyone rich, living in utopia. In Africa and most of the other un-developed world, there are people who dedicate 80% of there time collecting fire wood for energy to cook food and boil water.
