Det store barriererevet i Australia er redusert med 50% de siste 27 år, og vil sannsynligvis være helt borte i løpet av en 10 års tid i følge en ny forskningsrapport i PNAS.
- Australia’s iconic Great Barrier Reef is dying, and little will be left less than 10 years. More than half of the coral in the 2,300 km long reef has died over the past 27 years, according to a scientific survey released Monday.
- Storms and subsequent runoff directly account for 48 percent of the coral deaths. Crown of thorns starfish are responsible for 42 percent, with bleaching from too warm waters accounting for 10 percent, according the intensive survey of 214 of the 3,000 reefs in the GBR. Only three of the reefs surveyed were unaffected.
