  1. (A) Today, 3 million fishing boats operate and are greatly depleting the
    supply of fish and other aquatic life-forms. Over the past 40 years, fishing
    quotas have more than tripled. In 1950, 20 million tons of fish and marine
    products were harvested. By 1990, this amount had increased to 100 million
    tons per year. The depletion of fish stocks has led to overfishing in all
    oceans and other bodies of water. Past catches were generally higher than
    those of today due to overfishing. Therefore, to base today’s harvest limits
    on harvest numbers that were probably higher in the past would only
    accelerate the depletion of current fishing stocks.
