Sample Writing
Even thugh the ceans make up abut 70% f the earth's surface, mre than 80% f the ceans remain unexplred. While sme peple say that we shuld nt explre the ceans, their reasning is nt very sund. Explring is nt the same as expliting. When we explre a place, we g just t see and understand what is there.We shuld explre the cean, first and fremst, because we d nt knw what we d nt knw. We thught we knew many abut the cean, but we were wrng. There culd be life frms in the cean,
fr example, that fit nne f the neat categries we have fr life while we have n clue that they even exist.This brings up the secnd pint. We already knw many things abut the cean, but we need t learn mre. A gd example is cean acidificatin. We knw that it is causing cral t die. We knw that using less fssil fuel wuld cause the prcess t slw dwn. Hwever, we need t learn mre t find ut hw t stp it. We need mre research t see what is ging n, and t cme up with plans and slutins.Finally, t d this research, we have t enter an extreme envirnment nt very friendly t humans.
This requires the develpment f new technlgies that can als benefit us in ther areas. Fr example, in many ways, the deep cean resembles uter space. The technlgies can benefit each ther. Fr anther instance, the technlgy f a mechanical arm t cllect samples with has been used in factries and develpment f artificial limbs fr humans.All in all, there are many gd reasns t explre the ceans. If we care abut science, abut prtecting ur ceans, and abut develping new technlgies, we need t d all we can t supprtcean explratin.
