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.//
