Everyne gets excited by the news f the mst recent space flights, and I t share in peple’s sense f awe and wnder at the phts frm space that we see. Having said that, it is hard t believe that the high cst f space flight is justified s that we can get sme lvely pictures. We shuld be spending ur mney mre wisely, n what peple need. I cannt understand spending all mney n expensive research and experiments when s many peple need fd. Arund the wrld, millins f peple are hungry and dying f starvatin. On the ther hand, we hear n TV that fr as little as a dllar a day, a child in Africa can be saved. Cnsidering the billins spent n space travel, it just seems a better investment t feed the hungry.
Sme peple argue that smeday we will have t g live in space because the wrld will be made impssible t live in thrugh pllutin. This seems silly. When yur huse gets dirty, yu spend the time and mney t clean it up. Yu dn’t mve huse simply because yu need t wash yur windws r vacuum the flr. In the same way, it makes mre sense t use ur time and mney t take care f ur planet, rather than lk fr a new hme. Finally, there are a lt f unslved mysteries n the earth. S why are we ging int space t explre? There are still many things t discver in the cean depths and the Antarctic. But we d nt even have t g that far: Science has yet t unlck all the mysteries f the atm, and there are many realms f technlgy that we are just beginning t understand and explre.
