RIO DE JANEIRO, BRAZIL – An unpublished study conducted has found that around eighty percent of Brazil’s coral reefs – which are found predominantly off the coastline of the country’s northeast region, stretching 2,000km (1,240 miles) between Rio Grande do Norte and Bahia states,  have been lost over the last half century due to urban pollution and illegal removal. The group believes the remaining reefs are now threatened by climate change.

The startling results have emerged after a monitoring group from the Universidade Federal de Pernanbuco (Pernanbuco Federal University, UFPE) and the Ministério do Meio Ambiente (Ministry of Environment, MMA) began to monitor the state of the coral reefs in 2002.

The reefs are found along the coastline, as well as near bigger cities, such as Recife (whose name literally translates as “reef”), Maceió and Salvador – but untreated sewage from these large urban centers has caused irrevocable damage, and the corals have also been illegally removed.

UFPE’s Beatrice Padovani, who coordinated the study, told Globo’s G1 news site that “domestic, industrial and agriculture pollution,” as well as “increased sediment caused by the deforestation in the Atlantic forest and local mangroves” have caused the biggest damage, as well as removal for “construction, ornamentation and fishing.”

Using data from previous studies, the group have ascertained that the reefs have reduced by eighty percent. The study says overfishing is also threatening a number of fish species that depend on the coral.

Up to the 1980s the reefs were removed – by pick or explosive – for use in calcium oxide (quicklime) production, and the situation only then improved after specific legislation was brought in.

Extremely fragile and sensitive to changes in water conditions, coral reefs occupy less than 0.1 percent of the ocean’s surface and yet support a quarter of all marine species.

  1. “The group believes the remaining reefs are now threatened by climate change.”

    That’s just plain sad. I’ve been to that area and like Australia (which I’ve also been to) it’s really really sad. And yet, Hannity and Limbaugh, two “America is never wrong” mouth pieces that host talk radio shows in the U.S., willingly and wrongly both tell you it’s just panic-reaction from eco-terrorists; that global warming, according to experts, doesn’t exist. As I’ve said before, let either of those two step outside the studio and go see these places- the polar ice caps, Glacier National Park, etc.- in person for themselves, then compare them to photos just a few years past. Then go back on the air and claim “humans have nothing to do with it” as opposed to “Hey listeners, call in with suggestions on what you will do as an individual to help solve the problem”. I hope with the influx of recent money and economic expansion, Brazil uses their money wisely to preserver these things, i.e. the reefs, rain forest and other beauties (yes, the supply of Victoria’s Secret models too I suppose).
