Though these measures are certainly positive steps, no country acting alone can ensure adequate protection of shark populations. After all, sharks are global wanderers; they have no regard for the boundaries of economic exclusion zones, protected areas, or countries’ territorial waters.
虽然这些措施无疑可以算作积极步骤，但没有哪个国家单凭一己之力就足以保护鲨鱼种群。归根结底，鲨鱼是全球迁徙的物种；它们根本不管国家领海、专属经济区或保护区。没有国际协调行动，鲨鱼保护行动就不可能取得真正的效果。
