Gender Demographic Group Of The Media - 1382 Words

Homosexual Demographic Group Essay People in America tend to view media as an all-knowing, reliable source of information that affects their very lives. It’s no wonder that any form of demographic portrayal put in the media is automatically consumed by thousands of people every single day. This makes the mass media an important component in the society’s perception of many demographic groups. One of the most common demographic group thrown into the media is the LGBTQ. This organization was brought to America in 1988, however, sexuality is only a human feeling, existing from the time humans were evolved. The portrayal of the LGBTQ has evolved over time; Gays are more accepted now than they were around the 1950’s. â€Å"In 1980 to 90 the†¦show more content†¦As an American sometimes you have to ask yourself, why would the media in the past, or even now, try to dehumanize a group of people? It all depends on how you depict the situation. Nowadays, homosexu als are seen overall as almost a normal thing to be. We all are human, and we all bleed the same blood; However, things were not always how they are today. The Society of Human Rights was the first gay organization founded in 1924 by Henry Gerber. This organization immediately caused chaos and was disbanded almost instantly because of the political pressure. A majority of Americans saw gays as taboo and almost sickening. â€Å"1925 was the year police raids began to occur at gay and lesbian restaurants.†(United Church of Christ) One of the main reasons people looked down upon homosexuals was because of them being considered a threat. They were seen as sociopaths and psychos. Psychologists believed that homosexuals had sociopathic intentions and needed electric shock therapy. (PBS) During the Cold War in the 1950’s propaganda spread that stated that since homosexuality was a mental illness that â€Å"homosexuals were a security risk to the nation because those who eng age in overt acts of perversion lack the emotional stability of normal persons.† (PBS) Following this statement, years later, President Eisenhower banned homosexuals from working in any part of the federal government due to the risk they brought.

Why Do Whales & Dolphins Strand Themselves on Beaches

Few things in nature are more tragic than the sight of a pod of whales—some of the most magnificent and intelligent creatures on Earth—lying helpless and dying on the beach. Mass whale strandings occur in many parts of the world, and we dont know why. Scientists are still searching for the answers that will unlock this mystery. There are many theories about why whales and dolphins sometimes swim into shallow water and end up stranding themselves on beaches in various parts of the world. Some scientists have theorized that a single whale or dolphin may strand itself due to illness or injury, swimming in close to shore to take refuge in shallow water and getting trapped by the changing tide. Because whales are highly social creatures that travel in communities called pods, some mass strandings may occur when healthy whales refuse to abandon a sick or injured pod member and follow them into shallow water. Mass strandings of dolphins are far less common than mass strandings of whales. And among whales, deep-water species such as pilot whales and sperm whales are more likely to strand themselves on land than whale species such as orcas (killer whales) that live closer to shore. In February 2017, over 400 pilot whales were stranded on a New Zealand South Island beach. Such events happen with some regularity in the area, suggesting that the depth and shape of the sea floor in that bay may be to blame. Some observers have offered a similar theory about whales pursuing prey or foraging too close to shore and getting caught by the tide, but this seems unlikely as a general explanation given the number of stranded whales that have turned up with empty stomachs or in areas devoid of their usual prey. Does Navy Sonar Cause Whale Strandings? One of the most persistent theories about the cause of whale stranding is that something disrupts the whales’ navigation system, causing them to lose their bearings, stray into shallow water, and end up on the beach. Scientists and government researchers have linked the low-frequency and mid-frequency sonar used by military ships, such as those operated by the U.S. Navy, to several mass strandings as well as other deaths and serious injuries among whales and dolphins. Military sonar sends out intense underwater sonic waves, essentially a very loud sound, that can retain its power across hundreds of miles. Evidence of how dangerous sonar might be for marine mammals emerged in 2000  when whales of four different species stranded themselves on beaches in the Bahamas after a U.S. Navy battle group used mid-frequency sonar in the area. The Navy initially denied responsibility, but a government investigation concluded that Navy sonar caused the whale strandings. Many beached whales in strandings associated with sonar also show evidence of physical injuries, including bleeding in their brains, ears and internal tissues. In addition, many whales stranded in areas where sonar is being used have symptoms that in humans would be considered a severe case of decompression sickness, or â€Å"the bends,† a condition that afflicts SCUBA divers who resurface too quickly after a deep dive. The implication is that sonar may be affecting the whales’ dive patterns. Other possible causes put forth for the disruption of whale and dolphin navigation include: weather conditions;diseases (such as viruses, brain lesions, parasites in the ears or sinuses);underwater seismic activity (sometimes called seaquakes);magnetic field anomalies; andunfamiliar underwater topography. Despite the many theories, and growing evidence of the danger that military sonar poses for whales and dolphins worldwide, scientists have not found an answer that explains all whale and dolphin strandings. Perhaps there is no single answer. Edited by Frederic Beaudry
