海洋浩劫在加拿大新斯科细亚海岸不远处,有一块名叫乔治沙洲的浅水海域,那里曾经藏有丰富的鱼群。根据17世纪的文史数据记载,船只周围总是围绕着大群的鳕鱼、鲑鱼、条纹鲈鱼与鲟鱼。今日的光景却迥然不同。拖网渔船用以面积足球场般大的拖捞网从海底拖过,把海床都削去了一层,一日所获,连同整个生态系都给捞了起来,其中不乏支撑生态系的基质,如海绵。海洋更远处,延绳(longline)与流刺网钩住仅剩的鲨鱼、旗鱼和鲔鱼。这种劫掠式的疯狂捕捞,使这些经济鱼种的捕获量逐渐缩小,鱼的个体也越来越小,其中有许多鱼甚至还来不及长大就被捉起来了。这个现象不只局限在北大西洋,更涵盖了整个地球。许多人怀有错误印象,以为海洋物种的减少要归咎于污染,有些人则很难相信食用鱼种居然不足,因为附近的鱼市场里 Marine catastrophe Not far from the coast of Nova Scotia, Canada, there is a shallow waters called Georges sandbar, where there was a large number of fish stocks. According to 17th-century literary data, there are always large groups of cod, salmon, striped bass and sturgeons surrounding the ships. The situation today is very different. Trawlers have been dragged by seabed over an area of ​​soccer-like fishing nets and have been cut off by a single layer on the seabed. The first day, along with the entire ecosystem, has been brought to fishing. Many of them support the matrix of the ecosystem , Such as sponge. Farther out of the ocean, longlines hook onto shark nets for the remaining sharks, swordfish and anchovies. This grab-like frenzied fishing, the catch of these economic species gradually reduced, the fish individuals are getting smaller and smaller, many of them are even caught up with the fish too late to grow up. This phenomenon is not limited to the North Atlantic, but covers the entire earth. Many people harbor the false impression that the reduction of marine species is attributed to pollution and that some people find it hard to believe that the species of fish are not enough because of the nearby fish market
