Recommended: Water scarcity in easy words
When referring to Arizona’s water Kris Mayes, chairwoman of the state’s utility regulatory panel once said, “How do you say just how valuable water is in an arid state like Arizona?” she said. “It’s like the credit-card commercial-it’s priceless” (McKinnon). She was right, because in a dry state like Arizona, water is pretty important. To say water is ‘pretty important’ for the world is an understatement. We use water to function. And when we think of water we think of saving it. Keep the faucets from dripping or turn off the water while brushing your teeth. There are numerous tips for water conservation, but people don’t often think of the damage that is already done. Damages like ‘dead zones’. Dead zones in the ocean have been around for years and have been steadily growing.
So, what are ocean dead zones? It is exactly as the words suggest. Dead zones are areas in the ocean that have no life. When there is a decline in oxygen levels in the ocean marine life are unable to survive (Vogt). They either flee or die leaving those areas vacant while the zones expand. The dead zones end up looking like “biological deserts” (“What is”). Ocean dead zones are being caused by climate changes, synthetic fertilizers and toxic waste. By increasing biodiversity, stopping the use of synthetic fertilizers, and using ecotechnology will help lesson dead zones and are worth looking into.
Since the 1960s dead zones have doubled every 10 years (McDermott). In 2008 the number of dead zones were 400 (McDermott). They have been found near the coast of Asia, New Zealand, the Black Sea, and Australia, just to name a few (Yarbrough). They have also been found in Lake Eerie (“The Gulf of”). One of the largest ocean dead zones can be found in the Gulf of...

First the causes of the dead zone will be introduced. Large contributors of excessive nutrients will be discussed. There is not one source to blame the Chesapeake Bay dead zone is a large problem with many variables that effect each other. Next the pressure that is put on the bay and its organisms will be discussed. A picture of what you might find out in the dead zone will be painted. The reality of the rapidly declining organism populations will be understood. Third, the possible solutions will be explained. Since this is a multiple variable problem there are many potential solutions that may or may not work. Last the lack of action will be observed. There are many solutions that could bring the bay back to life but the cost and lack of effort fr...
During the summers the oxygen content atop the water normally has a salinity level consistent with “more than 8 milligrams per liter”; but when oxygen content drops down to “less than 2 milligrams per liter” the water is then known to be in hypoxic state (CENR, 2000; USGS, 2006). Hypoxia is the result of oxygen levels decreasing to the point where aquatic organisms can no longer survive in the water column. Organisms such as fish, shrimps, and crabs are capable to evacuate the area but the fauna that cannot move either become stress and/or die. Due to this, many call the hypoxia zone the “dead zone” (Overview, 2008; USGS, 2006).

Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to discover.

Freshwater in the world makes up only a small portion of the water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only 1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.
