India is standing at the threshold of a new frontier. But the most important question is not how deep we can go, how much we can mine, or how much wealth lies beneath the ocean floor. It is more fundamental: Should everything that can be technologically exploited necessarily be exploited? The question is particularly important as India strengthens its position in deep-sea exploration and develops the scientific and technological capabilities to access one of the least understood parts of the planet.
These achievements also impose a profound responsibility to decide whether technological ability should ultimately lead to exploitation. Technological progress can create a dangerous assumption: if we can exploit something, we should. But the deep ocean challenges this logic. We cannot confidently predict the consequences of large-scale seabed disturbance while our understanding of these ecosystems remains incomplete. This is not an argument against science, but for more science before potentially irreversible intervention. Deep-sea minerals may have legitimate strategic importance for India’s renewable-energy, electric-mobility and advanced-manufacturing ambitions. However, strategic importance cannot automatically become ecological permission. Before considering extraction, India should ask whether the minerals are genuinely necessary at the proposed scale, whether alternatives exist, and whether demand can be reduced through recycling, efficiency, substitution and a circular economy. Necessity must be demonstrated, not presumed. P. Ragavan is a marine biologist with over a decade of professional experience in the conservation and management of coastal and marine environments
Under the Deep Ocean Mission , India is developing deep-sea mining technology, underwater robotics and the MATSYA-6000 human submersible, while the National Institute of Ocean Technology has tested a mining machine at depths of about 5,270 metres. At the same time, biodiversity surveys across 19 seamounts have studied around 1,300 deep-sea organisms, including nearly 23 species reported as new to science.
It is a complex and poorly understood ecosystem, and India’s own biodiversity research continues to reveal previously unknown organisms.
