Intrduce the tpic
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.
Hw des the writer supprt the argument?

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(乳胶泡沫) 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 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.
