It seems we can’t get ff the planet fast enugh. Tw thirds f NASA’s mney is spent n manned space explratin, and that number will grw with the USA’s decisin t send a man t Mars in 2037. We’ve seen all there is t see n Earth, right? Wrng. The final place is here, under the surface f the sea.
Heading dwn int the cean, human limits are quickly reached. At 200 metres, the water is as black as a mnless night. Mst nuclear submarines (核潜艇) wuld implde (内爆) befre they reach 1 km dwn. At 3 km — still less than the average depth f the cean — there’s a gd chance that yu’ll discver a new species. The deepest-diving whales g n further. At the very bttm, abut 11 km dwn, lies the Challenger Deep, the deepest part f the Mariana Trench in the Pacific Ocean. Eighteen humans have walked n the Mn, but nly three have seen the Deep with their wn eyes.
Yet things live dwn there. Big things. A very lud sund was nce heard and scientists suggested that it was prduced by an animal bigger than a blue whale, the largest creature knwn n the planet.
In the late 1990s, a deep-water submarine was drpped in the Suthern Ocean, and passing 4, 000 metres, it discvered smething huge passing under it. Surprised? Dn’t be. The cean cvers 70% f the planet’s surface and we’ve studied less than 5% f it. We knw mre abut the dark side f the Mn than abut the bttm f the sea.
One reasn that we explre space is t find evidence f ther life frms. The search fr life utside f Earth is imprtant, but rbts can lk under the dry rcks f Mars better than humans. They’re abslutely imprtant fr ding cean research t, but they can’t lk under the sea. The cst f explratin is rising, but the results wuld benefit all ur lives. Understanding the ceans will help us find new surces f fd, drugs and energy.
Perhaps nw it’s time t begin a new perid f sea explratin. Manned explratin f space is science fictin. The adventure f the deep sea is science fact.

A study has warned that seafd supplies frm the wrld’s ceans culd be almst gne by the middle f the century.

As lng as we have been n earth, we have used the sea arund us. We take frm the cean, and we give t it.
We take fishes frm the cean — millins f kilgrams f fish, every year, t feed millins f peple. 1 We take minerals frm the cean.
