IELTS Writing Task 2: A Band 7.5 Essay (Is Ocean Exploration as Important as Space?), Graded

In today's era, exploration—whether of space or the oceans—is extremely important for the advancement of human knowledge. While some may advocate for space exploration due to its global attention, ocean exploration provides innumerable benefits such as mineral extraction, a deeper understanding of climatic systems and marine ecosystems, and improved disaster management. I strongly believe that ocean exploration must be promoted by governments and private organisations.

To begin with, as oceans are a vast habitat for marine life, understanding their ecosystems advances scientific research. For example, recent research suggests that a specific protein found in whales may help extend human longevity. Furthermore, oceans possess vast quantities of rare metals and minerals which are not only useful for industrial manufacturing, but also for the development of high-capacity hardware to power the next generation of artificial intelligence. Moreover, the study of the ocean's topography augments our weather prediction and disaster preparedness such as tsunamis and heavy floods. A pertinent example is the recent mapping of the tectonic plates near the Japan archipelago, which revealed a higher probability of tsunami occurrence in the next two decades.

Although many organizations champion space exploration, it demands heavy funding and may ultimately prove fruitless. For instance, a recent mission to Mars took years of research and yielded minimal returns. On the other hand, ocean exploration is comparatively less expensive and also requires shorter timeframes.

In conclusion, ocean exploration is as important as space exploration, if not more. It has shown substantial benefits to both private and public organizations by deepening our understanding of the natural world.
