淡水魚物種數(shù)量將“災(zāi)難性”減少

一份報告警告說，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.

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