Sample Writing
Space Explratin is a Waste f Time and Mneymade 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.In the end, it just des nt seem a very wise investment t g t space. We have t many needs here n the earth t be wasting ur effrt n space explratin.
