Part 8/10:
As researchers delve deeper into the depths of the Black Sea, they uncover evidence of its unique ecosystem and the effects of pollution, particularly hydrogen sulfide contamination. Below a depth of 150 meters, the Black Sea contains hydrogen sulfide, giving rise to a “dead zone” where life struggles to survive. Yet, some surprising discoveries have emerged; certain forms of life, such as archaea that thrive in methane-rich environments, reveal just how complex and resilient ecosystems can be under extreme conditions.
