In the sixteenth century, when Eurpoeans first ventured across the Atlantic to the northeast coast of the North American continent, they were amazed at the abundance of fish in the shallow waters of the Grand banks.
the fish are largely gone in early 1900, the fishing industry in Newfoundland collapsed, and despite efforts to help fish stocks to recover to date they have not done so.
some marine biologists suggest that the ecosystem has changed and that it might not be possible to return the environment to what was before and stabilize it at previous levels
