The world's stocks of afood will have collapd (暴跌) by 2050 at prent rates of destruction by fishing, a scientist said. By 2048, to be exact, catches of all the prently fished afoods will have decread 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 world's growing human population — expected to ri by 50 percent to nine billion in 2050.
Overfishing also destroys the stability of ocean environments largely, reducing the ocean'
s ability to produce afood, resist dias, filter (过滤) pollutants and rebound (回升) from stress such as climate change. And every species matters when it comes to the ocean's ability to repair itlf, 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 becau we will do something about it. But if this trend continues in this predictable fashion, as it has for the last 50 years, the world's currently fished afoods will have reached what we define (定义) as collap by 2048.”
“Every year a higher percentage of the currently fished stocks collap. 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 a are not merely embellishments (装饰) to be wondered at. They are esntial 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 rerves around not just Britain, but globally. ”
