Firstly, explring space has already made a difference in the fight against wrld hunger. It has directly resulted in the many satellites that nw rbit Earth. A number f the satellites recrd data n land and weather patterns. Then the data is transmitted t scientists n Earth After careful analysis, the scientists can prvide useful recmmendatins and advice fr farmers. As a result, space-based science has helped farming in its effrts t grw enugh fd t feed Earth's increasing ppulatin.
Secndly, space explratin has already prmted technlgical imprvements that benefit us all. High-end prducts arund the wrld are made t a higher standard nw because f advanced technlgy which was first created t meet the requirements fr space explratin. Fr example, space technlgies have helped the research and develpment f different types f new material. They have als helped cmpanies make better heart mnitrs and ther machines that dctrs regularly use. Tday, space technlgies are widely used in all kinds f industries, and everyday prducts such as GPS, memry fam pillws, and smartphne cameras are changing ur lives.
Finally, sending astrnauts int space has helped peple t think abut the wrld's prblems and even t find ways t slve them. Seeing pictures f ur planet as an island in a black sea made peple realise that ur planet's resurces are limited. In rder t prvide fr such a rapidly increasing ppulatin, scientists are trying t find ther planets that culd ne day be ur new hme. The greatest attentin at present is n Mars because it is clser t Earth, In the future, humans may live n bth planets.

最近，你班同学就“太空探索是否值得”这一话题展开了一场讨论。请你根据下表提供的信息，用英语写一篇短文介绍讨论的情况，并谈谈自己的看法。
Recently, students in ur class have had heated a discussin n whether space is wrth explring. Students hld different ideas abut it. 30% f us think space explratin is nt wrthwhile. They think space is t far away frm us and ur daily life and is a waste f mney. And the mney spent n space explratin can be used t slve the earth’s prblems such as starvatin and pllutin. On the ther hand，70% think space is wrth explring because we have benefited a lt frm it，such as using satellites fr cmmunicatin and weather frecast. What’s mre，with further space research，we may slve the ppulatin prblem by mving t ther planets ne day. Als，space research will enable us t find new surces t slve the prblem f energy shrtages n the earth. As far as I am cncerned, it is wrthwhile t explre the space. Nt nly can it prmte the develpment f sciety but als enrich ur life.
