Today there’sr r( 3 )rthat the resources ofthe sea are as seriously threatened as r( 4 )rof the land and theair. r r( 5 ), the threat to fish is greaterr r(6 )rthan the threat to birds and land animals because fish area r( 7 )needed food resource. Many people throughout the worldr r( 8 )rfish as an important part of their food and areductionr r(9 )rthe fish supply could have wider r( 10 )ron hunger and the population.
