As of 2018, our ocean, which takes up about 70 percent of our planet’s surface, is still 80 percent unexplored, nor observed. An expedition that was important for the exploration of our ocean, was the “Challenger Expedition,” which was led by Charles Wyville Thomson from 1872 to 1876. The voyage helped lay the foundation of oceanography. The vessel for the voyage was the HMS Challenger, which traveled 70,000 nautical miles that revealed existential information. As a result, the Challenger Expedition, impacted our understanding of how we view our ocean. Scientists aboard the HMS Challenger vessel sounded a trench that turned out to have a depth of 8,184 meters (26,850 feet). The truth is that the exploration of the “Mariana Trench” that followed years after its discovery, is only a very minor percentage of the world’s ocean that has been explored by humans. Our ocean provides life to thousands of species, and also sustains the life of many people across the world by supplying food and producing a generous portion of oxygen.

In recent decades, our beaches, oceans, and marine life have suffered immense damage from pollution consisting of oil spills, sewage, and hazardous chemicals. Oil companies have been irresponsible with the containment of their oil. The same irresponsibility is seen in many beaches across the world, as they have basically become disposal sites where nothing is being done to prevent or remove the trash. Beaches in Brazil, India, and Hawaii were places once seen as beautiful and clean, which made them frequently visited sites; however, they are now a dump. Trash has not been limited to only the beaches, but is also found in the middle of our oceans among the habitats of marine species. In a more dramatic and catastrophic manner, ocean levels are rising due to the increased temperatures that are melting glaciers on both poles of the Earth. Recent projections have indicated that within several years if the melting of glaciers remains the same, major cities in Africa and Asia will be underwater and will displace thousands of people from their homes. Actions must be taken quickly to prevent the displacement of perhaps millions of people across the world due to rising sea levels, and to take into account the importance of the ocean on our lives, and to maintain its hospitality toward many discovered and undiscovered species living in it. In the stage that we find ourselves in, rising sea levels may be inevitable, but our actions of reducing worldwide emissions of all kinds can contribute to the important task we have to slow down the pace rising sea levels currently have and avoid worldwide tragedies.
