The primary consequence of overfishing on marine life is the depletion of fish populations, leading to significant ecological imbalances. Overfishing disrupts food webs and can result in the collapse of target species, with cascading effects on associated marine organisms. This decline in biodiversity may affect predator-prey dynamics and ecosystem health. Additionally, genetic diversity may be compromised, making populations more susceptible to disease and environmental changes. Sustainable fishing practices are critical for preserving marine ecosystems and ensuring the long-term viability of fish stocks.
