• Biodiversity of the High Seas: They are home to around 2.7 lakh known species, many of which are yet to be discovered. 
• Regulate Climate: The high seas regulate the climate by playing a fundamental role in planetary stability by mitigating the effects of climate change through its absorption of carbon and by storing solar radiation and distributing heat around the globe.
• Anthropogenic Pressures on the High Seas: It include seabed mining, noise pollution, chemical spills and fires, disposal of untreated waste (including antibiotics), overfishing, introduction of invasive species, and coastal pollution.
