Land Waste Threatening Marine Life

About 5,400 kilometers of coastlines and 30 islands are threatened by marine pollution, said the Department of Environment’s deputy for marine environment. “Most sources of marine pollution—about 60%—are land-based,” she said on Friday, at the First Modern Engineering Design Conference in Tehran, Mehr News Agency reported. The official said the Caspian Sea shores in the north are being swamped by agricultural waste that make the water murky and reduce marine species. Even in the south, the coastlines of Persian Gulf and Sea of Oman are grappling with industrial waste. “Algal bloom and increased water temperatures caused by global warming are also threatening southern waters,” she said. Farshchi lamented years of mismanagement for Iran’s marine pollution and said fisheries in the northern provinces harvest only 250 tons of sturgeon annually—a marked drop from the 3,000-tons-a-year in the past 20 years.
