How Big Is The Ocean Persuasive Essay

The ocean is MASSIVE. I was personally astonished with the statistics and facts of the ocean. “As of 2013, the ocean contains upwards of 99% of the world's biosphere” (Gass,“How Big is the Ocean?”). We know that the human race heavily depends on the ocean. Oceans provide food, transportation, energies, etc. But are how are we using and affecting our oceans? How are we trying to resolve some of the issues caused by human interaction? And are there solutions to damage that's already been done? The following will attempt to answer these questions.

First, we need to recognize problems so that we are able to solve them. I have decided on 4 main problems that are at high concern and it will be discussed how these problems are substantially affecting

But claim that the average rate is increasing rapidly. But what about islands that can't afford not even inches of rise? Kiribati, located in Oceania, is currently experiencing the effects of sea level rise. This island's inhabitants are being forced to areas where there is no profit, no good farming soil and/or not suitable for humans because of the rising sea level. But they are not alone not only are there tons more islands that are facing this problem but also anyone living in coastal areas with low elevation. As of 2003, about 3 billion people lived within 200 kilometers of a coast line and it was predicted that the number would double by 2025. And as of 2007, 634 million people have been determined at risk from rising sea level. I found really cool satellite images of the Earth at night and you can tell that there's a lot of lights around the coasts. I have noticed that ocean warming and sea level rise are intertwined. Ocean warming affects sea level rise in different ways. As mentioned in the paragraph above, warmer waters expand and that increases sea level rise. Also as the ocean warms, ice caps and glaciers melt and let loose into our oceans so more water! The glaciers freeze above water so that's where their volume is at. When it melts, it melts into the ocean. Sea level rise also affects hurricanes because the water is already high

In global terms, fishing contributes 250 billion dollars per year to the economy. And 1 out of 7 people depend on fish for survival. So it can be assumed that fish affects the world, substantially. But it is important that we consider permanent damages to our oceans. It could be that the species I see throughout my lifetime will be extinct to my kids, or grandkids because of overfishing. Overfishing has been a problem for everyone around the world. Its when people fish a certain area faster than the species can reproduce. We have seen many situations in which we have over fished. For example, in the 1800s people needed blubber for lamp oil so the whale population dramatically decreased. Another good example is Bluefin Tuna. This species’ stock has quickly declined for more than one reason. Bluefin Tuna is a larger species of fish which is important to notice because large fish are more threatened by humans. “Big ole fish disappear first, and gradually as fishing intensifies, the species disappear in order of size” claims Professor Callum Roberts from the University of York. Bluefin Tuna are worth money therefore they are more of a target because of their size. In 2013, A Bluefin tuna sold for $1.7 million. Thats a lot of money! Secondly, since this species is larger, it takes longer to reach sexual maturity. And fishers tend to fish for the smaller ones so with excessive fishing, we are not giving species
