答案
Oceans
Almost three quarters of the earth’s surface is covered in water. / And around 90% of all the living space on Earth is contained in the oceans. /
These vast reserves cradled early life / and continue to be home to a wealth of extraordinary creatures. / At least 230,000 unique species have been documented, / although as humans have only explored a small fraction of the depths, / there may be as many as two million. /
As well as being home to marine creatures, / the oceans offer a range of critical services, / including acting as a source of food and regulating the atmosphere. / In particular, the oceans are also vital as sponges for green house gases. / Today, the oceans soak up around one third of all of human carbon emissions. / But this comes at a terrible cost. / The oceans are changing to contain more acid, / threatening the tremendous diversity of creatures that call them home. /
解析
海洋
几乎四分之三的地球表面被海水覆盖,地球上约90%的生活空间都包含在海洋中。这些巨大的储备空间孕育了早期生命并持续作为大量奇特生物的家园。除了为海洋生物提供栖息之地外,海洋还充当食物来源的角色以及起到调节大气环境的作用。
