Light Pollution : An Earthquake Shook Los Angeles

Now, as most may know sea turtles are both marine and land animals depending on what stage of life they are in. Which means that they need to be able to go on land during certain stages of their lives. One of the main reasons why a sea turtle will go on to land is to lay their eggs. Within the last few years this has become harder and harder for the already endangered species. It

While Verlyn Klinkenborg has good authority on this topic he uses very little evidence that has been researched and proven. He only mentions two scientific studies. One talks about how light attracts animals and the other is a study that connects brightness in neighborhoods. Throughout the essay he gives what seems to be logical evidence that light pollution has a negative effect, but he is no scientist. The use of reliable scientific sources cited in the essay would have been better evidences. Klinkenborg could have supported his argument using sources.

Humans have heavily affected sea turtle mortality rates, but one may ask what the benefit of having a stable and healthy population of sea turtles is. Sea turtles hold many important roles in both terrestrial and marine ecosystems where they are found. Along coasts where sea turtles are found nesting, beaches have been seen to have an increase in organic matter, phosphorus, nitrogen, and lipids (Bouchard 2000). This matter left by the sea turtle is in the forms of unhatched eggs and eggshells, which are then brought into the food chain through decomposers, such as beetles, or sea turtle predators, such as crabs (Bouchard 2000).

California’s unique geography as a state makes it a very appealing place to call home. From the odd east to west transverse San Gabriel mountain ranges of the Los Angeles Basin, to the bumpy coastal ranges of the Bay Area, any person can find a compatible topographic terrain to their liking. California may seem to be the perfect place to live with its ideal climate and extensive geographic features. However, due to California’s location over the shifting continental plates, coupled with its enormous and also multiple faults, at any time this great state can fall victim to a seismic disaster. After examining evidence from both Rong-Gong Lin’s II Los Angeles Times article of April 18, 2016 and the NOVA videos Killer Quake ( 2006), Earthquake (2007), as well as Geologic Journey II – Episode 3 (The Pacific Rim: Americas) – Part 3 (San Francisco) and The Great San Francisco Earthquake (American Experience ~ 2005), one can take a comparative account of the three major earthquakes of California’s past. Although each earthquake was very devastating on is own; the Great Quake 0f 1906, the Loma Prieta quake of 1989, and the NorthRidge quake of 1994 each amounted to an extensive forfeiture of property and life. Each of these earthquakes created much suffering and loss. It is imperative for each citizen of this great state to understand the damage that a California quake can actually do and be prepared; for the threat of one always looms.

The San Francisco Earthquake written by Jack London is journal of his events throughout the devastating acts of God that hit San Francisco in 1906. (461-466)

The pictures from the L.A. Times are a snap shot of the devastation that occurred in San Francisco on April 18, 1906, and they are riveting. There are men and women in period dress standing in the streets surrounded by swirls of water, and looking ahead down a hilly street to the plumes of smoke overtaking the city. It began with an earthquake between 7.8 and 8.3 magnitude on April 18, 1906 at around 5:12 to 5:13 AM, and ended in three days of fires with 90 percent of the city in ruins and an estimated 3,000 lives lost. After several days of fires, building and houses laid gutted and in ruins. Why was the earthquake so deadly and how could it cause such devastation?

What did the people of San Francisco suffer after the earthquake of 1906? In order to answer this question, we need to know what the San Francisco earthquake was. The San Francisco earthquake happened in 1906 with a magnitude of 7.8 and caused a fire that burned for 7 days. This was the biggest recorded earthquake in San-Francisco. The foreshock started at 5:12am and 25 seconds later the earthquake started that lasted 40 to 60 seconds, with most San-Franciscans asleep in rooms, they became trapped with only their hope to save them. The earthquake and fire of San-Francisco in 1906 will go down as one of the worst earthquakes in the United States’ history. It’s after affects can still be felt in the California area.

Bogard starts building his argument from the very beginning of his article. He builds his argument fact by fact to give you multiple reasons to understand the need to reduce light pollution. He states that "the World Health Organization classifies working the night shift as a human carcinogen." Without darkness our bodies are unable to perform some of the daily functions that we need, such as sleep and melatonin production. Without these, we are more likely to develop disorders such as diabetes and depression.

“ Computer images of the United States at night… show that what was a very dark country as recently as the 1950s is now nearly covered with a blanket of light. “ Using this to make us really think about the beauty of nature and what we are missing. Bogard brings in our health to give us a view of different problems that could occur beside losing the beauty of darkness, “Already the World Health Organization classifies working the night shifts as a problem human carcinogen, and the American Medical Association has voiced its unanimous support for “light pollution reduction efforts and glare reduction efforts at both the national and state level.” Putting the reader on an edge as we see more problems appear throughout the

The green sea turtle occurs throughout tropical and subtropical oceans and is among the largest of the hard-shelled sea turtles growing to as much as 440 pounds and four feet in length. The breeding populations in Florida were listed as endangered in 1978 (43 FR 32800 32811, July 28, 1978) whereas all other populations were listed as threatened (NOAA 2015h). There is a proposal for identification of a North Atlantic green sea turtle distinct population that would be listed as threatened, continuing its current listing status near New York (80 FR 51763 51764, August 26, 2015). They are found in the shallow waters (except during migration) of shoals, bays, lagoons reefs, and inlets, often where submerged aquatic vegetation exists, from Maine south to Florida, and throughout the Gulf of Mexico and the Caribbean Sea (USFWS 2015n, 2015o; NOAA 2015e). Green sea turtles nests are not present in New York; however, they occasionally are found stranded on or near the shore (NYSDEC 2015ad). Breeding takes places in subtropical to tropical oceans every two, three, or four years between June and September, with peak nesting in June and July (NOAA 2015h; USFWS 2015u). Hatching usually occurs at night, and many green sea turtle hatchlings seek refuge and food in masses of floating sea plants (USFWS

The lighting causes many turtles to die by leading them away from the moon which can cause dehydration, getting run over, Etc. There are turtles being born each year and 100-300 turtles are dying each year due to the lighting on beaches. If the turtles are being affected by lighting on the beaches many things could happen. A few examples are that the turtles will soon be extinct and we soon will not be able to see their beauty. The other animal rates could go down also because some of the animals need to eat the turtles to survive. People should stop putting the lights near the beach now. It kills the loggerhead turtles each year and soon they will become extinct.

Light pollution is a comparatively unknown and yet relatively serious problem that is constantly growing. Because of the way most lights are designed they throw light not just down, where it's needed, but also up and to the sides. This causes unnecessary light to be cast that can disorient animals as well as throw off their normal routines.

Sea turtle hatchlings are now having trouble finding their way to the sea because of all the lights from buildings that are built on the coast. They get disoriented when they are born and will wander in the wrong way away from the sea. This leads them to predators that live inland or will even cause the turtle to become dehydrated and die. Humans are also building coastal armoring that is blocking female turtles from reaching a suitable nesting habitat. This is a severe problem in Florida where they have many coastal rock elevations and sand bags. Where all this beach development is occurring thousands of sea turtles are trying to nest. Beach dredging is also having a direct effect on sea turtle's trying to nest. If the sand is too impacted or is drastically different from native beach sediment, the mother will have trouble creating the

Imagine a world of chaos. We see things like that all the time in movies, where zombies roam the earth and there are just those few main survivors left. The world is in ruins. If ocean life was to die out, there would be a collapse of civilization as a whole. Just like we see on TV, the world would become a place where no order exists. This would lead to human extinction. The ocean dies, we die along with it, and if sea turtles die, so does the ocean. In simple words, one could say that human life depends on sea turtles. In this speech I will be covering three topics. First, how a sea turtle’s diet benefits marine life and humans, second, how sea turtles provide homes and food for other species, and last, how sea turtles protect beaches from washing away.
