IS EXPLORING SPACE


A WASTE OF TIME AND MONEY？


Cuntries arund the glbe are spending billins f dllars and lts f time n varius space missins，whether t Mars r ther planets much further away.Sme peple argue that we shuld stp wasting time and mney explring space.Instead，we shuld feed the wrld’s pr and find immediate slutins t ther prblems，such as pllutin and fatal diseases.Hwever，thers feel this is a shallw view which fails t realise hw explring space helps us.


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 their 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 planets’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.


In clsing，explring space prvides the wrld with many different benefits.Therefre，it shuld cntinue s as t prvide new and better slutins t peple’s shrt－term and lng－term prblems.
