Scientists had known for years that they were coastal environments with high carbon storage, but because...

The McMurdo Dry Valleys are a row of valleys west of McMurdo Sound, Antarctica, so named because of their extremely low humidity and lack of snow and ice cover. Photosynthetic bacteria have been found living in the relatively moist interior of rocks. Scientists consider the Dry Valleys to be the closest of any terrestrial environment to Mars.

Scientists calculated that 275 million metric tons of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million metric tons entering the ocean. This map shows the estimated mass of mismanaged plastic waste from each coastal country; the darker the color, the larger the amount; countries shaded in white were not included.
