My pinin abut space explratin With the develpment f science and technlgy, space explratin is becming a ht tpic. Sme peple argue that space explratin wastes a large amunt f mney and time. Hwever, thers believe that it is really wrthwhile. Space explratin is a challenge t human beings, but I believe it has mre advantages. Firstly, space technlgies has helped prduce many high-end prducts that imprve ur daily lives such as GPS, smartphne cameras and s n. Secndly, it is necessary t find a new hme fr peple in space, as the resurces n Earth will run ut. Space explratin makes us better understand the uter envirnment, which is necessary fr us t make gd use f the natural resurces. Finally, explring space can extend ur hrizn beynd the earth and satisfies ur curisity abut the mystery f the universe. In clsing, space explratin brings mre benefits fr humans. S we shuld pay mre attentin t it and supprt it.
My pinin abut space explratin In recent years, many cuntries have spent billins f dllars and lts f time n explring space. Sme peple think it is wrthwhile t d this. Hwever, thers argue that it is a waste f time and mney and we shuld stp space explratin. First f all, althugh many benefits may result frm space explratin, the csts invlved are enrmus. As we all knw, explring space requires a great deal f mney n space equipment, training astrnauts and ding experiments. Secndly, ur wrld is faced with many unslved prblems, such as envirnmental pllutin and fatal diseases. S why are we ging int space t explre? Finally, there are many peple suffering hunger. I can't understand spending all this mney n expensive research and experiments when s many peple need fd. All in all, we shuld spend mney and time caring fr peple arund the wrld instead f explring space.
