They believed the world and nature would continuously reproduce all the resources they would need. For example, a【B2】______ biologist writing in the mid-nineteenth century commented that none of the great sea fisheries were to be【B3】______. Today, though, there is evidence that the resources of the sea are seriously endangered.
【B4】______, environmentalists have focused their attention on the land and air. Recently, however, they are beginning to discover that the resources of the sea are in as much danger. The list of endangered 【B5】______ now included herring and crabs as well as the African elephant, Indian tiger, and the American eagle.
Furthermore, the threats to fish are more【B6】______in some ways than the threats to animals and birds. This is because fish are a much more needed food source, and people【B7】______ depend on fish as an important part of their diet. Hence, a decline in the fish supply could have【B8】______ effects on hunger and population. Fishermen in the North Atlantic alone annually harvest 20 billion pounds of fish to 【B9】______ food demand, but the world needs to recognize that these practices cannot continue without depleting fish reserves within the next few years. Rapidly declining sea resources in many parts of the world are problems that cannot be ignored any longer. Unlike the【B10】______in the nineteenth century, we now know that food supplies in the sea cannot last forever.
