Salmon Farming: The Chilean Massive Die-Off

Last year, Chile exported $4.5 billion of farmed salmon, but now a deadly algal bloom is killing millions of farmed fish.

Many causative effects for this decline are known, but many remain to be clarified. Politics often prevents adequate investigation of...

Do Sea Turtles Eat Plastic Marine Debris? Yes!

By The Editors Floating marine debris accumulates in five main oceanic gyres. These debris accumulations consist mostly of plastics and are called great garbage patches. In recognition of the global threat posed by the great garbage patches, the United Nations Educational, Scientific and Cultural Organization (UNESCO) has recently granted them a symbolic State status, and officially recognized the Garbage Patch State. Marine debris...
