Referring to Arizona water, Kris Mayes, chair of the state's utility regulatory committee, once said, "How can you tell How precious is water in a dry state like Arizona? she said. “It's like credit card advertising: it's priceless” (McKinnon). She was right, because in a dry state like Arizona, water is very important. To say that water is “pretty important” to the world is an understatement. We use water to function. And when we think of water, we think of conserving it. Stop faucets from running or turn off the water while brushing your teeth. There are many tips for saving water, but people don't often think about the damage they've already done. Damage such as “dead zones”. Dead zones in the ocean have existed for years and are growing. So, what are ocean dead zones? This is exactly what the words suggest. Dead zones are areas of the ocean where there is no life. When there is a drop in oxygen levels in the ocean, marine life is unable to survive (Vogt). They either flee or die, leaving these areas vacant as the zones expand. Dead zones end up looking like “biological deserts” (“What Is”). Ocean dead zones are caused by climate change, synthetic fertilizers and toxic waste. By increasing biodiversity, stopping the use of synthetic fertilizers and using ecotechnology, we will help learn lessons from dead zones and are worth studying. Since the 1960s, dead zones have doubled every 10 years (McDermott). In 2008, the number of dead zones was 400 (McDermott). They have been found near the coasts of Asia, New Zealand, the Black Sea, and Australia, to name a few (Yarbrough). They have also been found in Lake Eerie ("the Gulf of"). One of the largest ocean dead zones is in the Gulf of...... middle of paper...... New Jersey. " Daily Nature and Science News and Headlines | National Geographic News.
