  Deep sea mining might stress out jellyfish, starve them to death, warn scientists   Environmental scientists and biologists often raise concerns about the potential unintended consequences of human activities in the deep sea. The deep ocean is a poorly understood and fragile ecosystem, and disturbances to this environment could have cascading effects on marine life. The expansive underwater communities of the world remain largely unexplored and surprisingly under-studied. However, a recent publication in Nature Communications provides initial insights into how deep pelagic jellyfish respond to stressors associated with global warming and deep-sea mining-induced sediment mounds. Deep-sea drilling is of concern among scientists and environmentalists because of its potential impact on marine ecosystems. Deep-sea mining involves extracting valuable minerals and resources from the ocean floor. The process can cause habitat destruction, change sediment patterns, and rele...
