Environmental disaster in the context of "Karakum Canal"

The San Juan Mountains is a high and rugged mountain range in the Rocky Mountains in southwestern Colorado and northwestern New Mexico. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range. The last large-scale mines were the Sunnyside Mine near Silverton, which operated until late in the 20th century, and the Idarado Mine on Red Mountain Pass, which closed in the 1970s. Famous old San Juan mines include the Camp Bird and Smuggler Union mines, both located between Telluride and Ouray.

The Summitville mine was the scene of a major environmental disaster in the 1990s when the liner of a cyanide-laced tailing pond began leaking heavily. Summitville is in the Summitville caldera, one of many extinct volcanoes making up the San Juan volcanic field. One, La Garita Caldera, is 35 miles (56 km) in diameter. Large beds of lava, some extending under the floor of the San Luis Valley, are characteristic of the eastern slope of the San Juans. The eruption of the La Garita Caldera shaped the San Juan Mountains by completely obliterating the volcanoes that once stood in the area.

A dystopia (lit. "bad place") is an imagined world or society in which people lead wretched, dehumanized, fearful lives. It is an imagined place (possibly state) in which everything is unpleasant or bad, typically a totalitarian or environmentally degraded one. Dystopia is widely seen as the opposite of utopia – a concept coined by Thomas More in 1516 to describe an ideal society. Both topias are common topics in fiction. Dystopia is also referred to as cacotopia or anti-utopia.

Dystopias are often characterized by fear or distress, tyrannical governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society. Themes typical of a dystopian society include: complete control over the people in a society through the use of propaganda and police state tactics, heavy censorship of information or denial of free thought, worship of an unattainable goal, the complete loss of individuality, and heavy enforcement of conformity. Despite certain overlaps, dystopian fiction is distinct from post-apocalyptic fiction, and an undesirable society is not necessarily dystopian. Dystopian societies appear in many sub-genres of fiction and are often used to draw attention to society, environment, politics, economics, religion, psychology, ethics, science, or technology. Some authors use the term to refer to existing societies, many of which are, or have been, totalitarian states or societies in an advanced state of collapse. Dystopias, through an exaggerated worst-case scenario, often present a criticism of a current trend, societal norm, or political system.

The Immigration Act of 1990 (Pub. L. 101–649, 104 Stat. 4978, enacted November 29, 1990) was signed into law by George H. W. Bush on November 29, 1990. It was first introduced by Senator Ted Kennedy in 1989. It was a national reform of the Immigration and Nationality Act of 1965. It increased total, overall immigration to allow 700,000 immigrants to come to the U.S. per year for the fiscal years 1992–94, and 675,000 per year after that. It provided a family-based immigration visa, created five distinct employment based visas, categorized by occupation, and a diversity visa program that created a lottery to admit immigrants from "low admittance" countries or countries whose citizenry was underrepresented in the U.S.

Besides these immigrant visas there were also changes in nonimmigrant visas like the H-1B visa for highly skilled workers. There were also cutbacks in the allotment of visas available for extended relatives. Congress also created the temporary protected status (TPS visa), which the Attorney General may provide to immigrants who are temporarily unable to safely return to their home country because of ongoing armed conflict, an environmental disaster, or other extraordinary and temporary condition. It specifically benefited citizens of El Salvador.

The 2000 Baia Mare cyanide spill was a leak of cyanide near Baia Mare, Romania, into the Someș River by the gold mining company Aurul, a joint-venture of the Australian company Esmeralda Exploration and the Romanian government.

The polluted waters eventually reached the Tisza River and then the Danube, killing large numbers of fish in Hungary, Serbia, and Romania. The spill has been called the worst environmental disaster in Europe since the Chernobyl disaster.

The Deepwater Horizon oil spill was an environmental disaster beginning 20 April 2010 off the coast of the United States in the Gulf of Mexico, on the BP-operated Macondo Prospect. It is considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at 4.9 million barrels (210,000,000 US gal; 780,000 m). After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history.

A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and 1,840,000 US gal (7,000 m) of oil dispersant. Due to the months-long spill, along with adverse effects from the response and cleanup activities, extensive damage to marine and wildlife habitats and fishing and tourism industries was reported. In Louisiana, oil cleanup crews worked four days a week on 55 mi (89 km) of Louisiana shoreline throughout 2013. 4,900,000 lb (2,200 t) of oily material was removed from the beaches in 2013, over double the amount collected in 2012. Oil continued to be found as far from the Macondo site as the waters off the Florida Panhandle and Tampa Bay, where scientists said the oil and dispersant mixture is embedded in the sand. In April 2013, it was reported that dolphins and other marine life continued to die in record numbers with infant dolphins dying at six times the normal rate. One study released in 2014 reported that tuna and amberjack exposed to oil from the spill developed deformities of the heart and other organs which would be expected to be fatal or at least life-shortening; another study found that cardiotoxicity might have been widespread in animal life exposed to the spill.

The Kingston Fossil Plant Spill was an environmental and industrial disaster that occurred on December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons (4.2 million cubic metres) of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, used a series of ponds to store and dewater the fly ash, a byproduct of coal combustion. The spill released a slurry of fly ash and water which traveled across the Emory River and its Swan Pond embayment onto the opposite shore, covering up to 300 acres (1.2 km) of the surrounding land. The spill damaged multiple homes and flowed into nearby waterways including the Emory River and Clinch River, both tributaries of the Tennessee River. It was the largest industrial spill in United States history.

The initial spill, which resulted in millions of dollars' worth of property damages and rendered many properties uninhabitable, cost TVA more than $1 billion to clean up and was declared complete in 2015. TVA was found liable for the spill in August 2012 by the U.S. District Court for the Eastern District of Tennessee. The initial spill resulted in no injuries or deaths, but several of the employees of an engineering firm hired by TVA to clean up the spill developed illnesses, including brain cancer, lung cancer, and leukemia, as a result of exposure to the toxic coal ash, and more than 30 had died within 10 years of the spill. In November 2018, a federal jury ruled that the contractor did not properly inform the workers about the dangers of exposure to coal ash and had failed to provide them with necessary personal protective equipment. After rejecting multiple offers, workers reached a settlement with the contractor in May 2023.

The Exxon Valdez oil spill was a major environmental disaster that occurred in Alaska's Prince William Sound on March 24, 1989. The spill occurred when Exxon Valdez, an oil supertanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef, 6 mi (9.7 km) west of Tatitlek, Alaska at 12:04 a.m. The tanker spilled more than 10 million US gallons (240,000 bbl) (or 37,000 tonnes) of crude oil over the next few days.

The Exxon Valdez spill is the second largest in U.S. waters, after the 2010 Deepwater Horizon oil spill, in terms of volume of oil released. It is the costliest disaster ever with no direct human fatalities. Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. The region is a habitat for salmon, sea otters, seals, and seabirds. The oil, extracted from the Prudhoe Bay Oil Field, eventually affected 1,300 miles (2,100 km) of coastline, of which 200 miles (320 km) were heavily or moderately oiled.
