Green Ships: Keeping Oceans Blue

摘要

A famous quote of Arthur Clarke is often cited: "How inappropriate to call this planet Earth, when clearly it is Ocean." More than 70 percent of Earth's surface is liquid water, most of it sparkling blue oceans that cover nearly 140 million square miles of Earth, a greater area than all continents combined (McMillan & Musick, 2007). It is vital that we promote the manufacturing of Green Ships that don't pollute the environment and strengthen the laws that prohibit waste dumping so oceans stay clean and healthy; otherwise, the direct output of this concept-the existence of humanity in the years to come-will be questionable.
