Space development should be pushed forward/for our future. There are at least three advantages/that should be noted.
　First,/humans can obtain mineral resources and new substances/in space. It has been found/that meteorites coming from space/sometimes contain minerals/such as iron, nickel, and platinum. This fact shows the possibility/that humans can find these mineral resources/on other planets. In addition,/a new substance/which does not exist on the earth/may be discovered. With such a new substance,/it might be possible/to develop new materials and medicines.
　Next,/space development can lead/to the advancement of technology. For example,/to improve satellites, rockets, and the space station,/new technologies have been created. These technologies have contributed/to making better solar panels, water purifiers, and calculators. Advanced technologies for space development/are also useful/for peoples’ everyday lives.
　Finally,/humans can understand the earth/more deeply. It is said/that water and organic substances,/which are essential for life,/were brought to the earth/by meteorites from space. However, the truth is still unknown. The exploration of space may help solve the mystery/of how life began on the earth.
　Because of these advantages,/human beings should prioritize space development/over all other things.
