Who Will Own Deep-sea Life
Ever since human’s early ancestors first peeled shellfish along the southern coast of France 300,000 years ago, food has been the measure of the bounty (物产) of the sea. These days, however, the notion of that bounty is expanding. Increasingly, it includes genetic building blocks contained in unique deep-sea creatures that thrive under conditions once thought impossible for sustaining life.
But as biotech companies begin to eye these organisms as a potential source of raw material for medicines and other products, calls are emerging for rules of the road to help ensure that the benefits of deep-sea gene prospecting are shared globally. Admittedly, most biotech and pharmaceutical companies are not yet rushing to hydrothermal (热液的) vents, sea mounts, and other unique habitats to dig up organisms and figure out if they can be useful. The vast majority of marine bio-prospecting these days is done in shallower wa
A. the lack of clear rules governing it
B. the lack of government’s support of exploiting it
C. the poor prospect of exploiting it
D. the lack of commercial interests of pursuing it
