A new 33 hopes to change this. Smoothly launched in London on April 27th, Ocean Census (海洋普查)aims to discover 100, 000 new species of marine animal over the coming decade.
The attempt is happening now for two reasons. One is that, the longer scientists 34 , the fewer there will be to document. Climate change is heating the oceans, as well as making them more acidic as carbon dioxide is absorbed into the water.
The second one is technological. Marine biologists discover about 2, 000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census is 35 it can go faster. “Cyber taxonomy(网络分类学)”, for instance, involves feeding animal DNA information into computers, which can quickly decide whether it meets the 36 for a new species.
