will have decreased on average by more than 90 percent since 1950. the study says the loss of biodiversity (生物多样性) cuts down the ability of oceans to feed the worlds growing human population expected to rise by 50 percent to nine billion in 2050.overfishing also destroys the stability of ocean environments largely，reducing the oceans ability to produce seafood, resist diseases, filter (过滤) pollutants and rebound (回升) from stresses such as climate change. and every species matters when it comes to the oceans ability to repair itself, says the study.dr. boris worm, of dalhousie university, nova scotia, the lead author, said, “this is what is projected, not predicted, to happen. i am confident we will not go there because we will do something about it. but if this trend continues in this predictable fashion, as it has for the last 50 years, the worlds currently fished seafoods will have reached what we define (定义) as collapse by 2048.”“every year a higher percentage of the currently fished stocks collapse. we are losing it piece by piece.” prof callum roberts, of the university of york, who was not involved in the study, said，“the animals and plants that inhabit the sea are not merely embellishments (装饰) to be wondered at. they are essential to the health of the oceans and wellbeing of human society. we need to ban destructive fishing practices and create a network of largescale marine reserves around not just britain, but globally.”语篇解读：本文主要讲了过度捕捞造成的生物多样性消失最终将使海洋养活不了增长的世界人口。1according to the passage that all seafood will run out in 2050 will _amake the
