淡水魚物種數(shù)量將“災(zāi)難性”減少

一份報(bào)告警告說(shuō)，淡水魚的數(shù)量將出現(xiàn) “災(zāi)難性” 下降，近三分之一的淡水魚面臨滅絕的威脅。

More than half the world's fish are found in lakes, rivers and wetlands – from carp and minnow to giant catfishare disappearing, and the European eelremained critically endangered.

在英國(guó)水域，鱘魚和江鱈已經(jīng)絕跡；鮭魚正逐漸消失，而歐洲鰻鱺仍處于極度瀕危狀態(tài)。

According to the WWF, much of the decline is driven by the poor state of rivers – mostly as a result of pollution, dams and sewage.

世界自然基金會(huì)指出，造成數(shù)量下降的主因是河流狀況不佳，這主要?dú)w咎于污染、筑壩和污水排放。
