Aggressive seaweed smothers one of world`s most remote reefs
(World News USA)

HONOLULU (AP) — Researchers say a recently discovered species of seaweed is killing large patches of coral on once-pristine reefs and is rapidly spreading across one of the most remote and protected ocean environments on earth. A study from the University of Hawaii and others says the seaweed is spreading more rapidly than anything they`ve seen in the Northwestern Hawaiian Islands, a nature reserve that stretches more than 1,300 miles north of the main Hawaiian Islands. The study was published in the journal PLOS ONE on Tuesday.
