activity in the entire world is having a very serious effect on the health of the oceans as a whole. When commercially valuable species are overexploited‚ other species and habitat that share the same ecosystem are affected. According to many marine scientists and marine ecologists‚ unsustainable (overfishing) fishing is the greatest threat to the ocean ecosystems. For example‚ recent scientific studies suggest that overfishing of large shark species has had a ripple effect in the shark’s food chain‚ increasing
