In the 19th century, it was often to hear people in America and Europe say that the resources of the sea could not be used up. Today there is evidence(迹象) that resources of the sea are as really threatened(威胁) as those of the land and the air. Further, the threat to fish is more serious(严重) in some ways. than the threat to birds and land animals because fish are a much needed food resource. Many people throughout the world depend on fish as an important part of their food. Fishermen in the North Atlantic alone every year harvest 20 billion pounds of fish to satisfy food demands. But it is important to know that these practices cannot continue without using fish resources within the next few years.
It is only with care and planning in this generation(一代人) that the food supplies of the sea can continue for future generation.
