Overfishing, a Major Threat to the Global Marine Ecology - Environment Alert Bulletin 4

In 2002, 72% of the world's marine fish stocks were being harvested faster than they could reproduce. Fishing activities have various negative impacts on marine ecosystems. The greatest concern is the rapid depletion of fish population due to extensive commercial fishing. A full one-fourth of the total catch (27 million tones in 2003) is not those targeted, and most often are lost.
