Man-made mercury pollution has reached the deepest seabed, according to scientists. Two groups of scientists from China and the United States found toxic mercury in fish and crustaceans that live more than 11 thousand meters below sea level — precisely in the Mariana Trench. "This is shocking. Previous research stated that mercury was found in the top several hundred meters of the ocean. That way, deep sea animals are unlikely to swallow the hazardous substance. But now, we know that's not true, said Dr. Ruoyu Su, research leader from Tianjin University in China. Also Read: The Sky Looks Clean During Pandemic, Are Emissions Reducing? Mercury, which is ingested by small marine animals, can ultimately endanger larger species when they eat the organism.

The Ocean Health Index (OHI), developed by the National Center for Ecological Analysis and Synthesis (NCEAS) and Conservation International, ranked Indonesia 137th out of 221 countries in 2018, with a total value of 65 out of a scale of 100. This value is still below the average global sea health of 71.

"If we are buried in the ground, we cannot live because we cannot farm, we cannot farm, we cannot have livestock." While cross-legged under the granary of ancestral remains, Layuk revealed that Toraja is a plateau consisting of rock hills and most of it is non-productive land. It was this understanding of the Toraja natural condition that made the ancestors of Layuk set an example for their successors to bury their dead on rock cliffs - a tradition that continues to this day.
