Earth's oceans are growing darker, threatening marine life worldwide: study

A recent study has found that Earth's oceans are growing significantly darker, posing a threat to marine life worldwide. According to satellite data, 21% of the world's oceans have experienced a decline in brightness over the past two decades. This darkening is primarily attributed to changes in plankton populations, which play a crucial role in the marine food chain. The study's findings suggest that the reduction in ocean brightness is affecting the photic zone, the uppermost layer of the ocean where photosynthesis occurs. This change can disrupt the delicate balance of marine ecosystems, impacting the growth and development of various species, including fish, coral, and other marine organisms. Researchers warn that the consequences of this darkening could be severe, with potential impacts on global food security, the carbon cycle, and the overall health of the world's oceans. The study emphasizes the need for further research and immediate action to address the underlying causes and mitigate the effects of this alarming trend.
