Озеро Гижгит находится в Баксанском ущелье Кабардино-Балкарии, недалеко от поселка Былым. Взглянув на озеро, сложно представить, что подобная красота является рукотворной, и к сожалению, даже таит в себе угрозу.
Строго говоря, озеро Гижгит совсем не озеро, а запруда одноименной реки. Дело в том, что в 1940-2000 годы примерно в 10 км от этого места рядом с г. Тырныауз действовал Тырныаузский горно-обогатительный комбинат (ТГОК), специализирующийся на добыче и обогащении вольфрамо-молибденовых руд. В 1966 году в русле реки Гижгит, которая является притоком бурной горной реки Баксан, для нужд ТГОК было построено третье (основное) хвостохранилище, или, если говорить проще, отстойник токсичных отходов производства. Устье реки было перегорожено плотиной, в результате чего в русле горной реки образовалось водохранилище, называемое сейчас озером. Сток воды из озера Гижгит осуществляется по специальному отводному тоннелю в реку Баксан.
Хвосты — профессиональный термин, обозначающий отходы производства руды, зачастую токсичные. Хвостами называют токсичные отходы обогащения полезных ископаемых, соответственно хвостохранилище – комплекс специальных сооружений, предназначенный для их хранения и захоронения.
В годы работы комбината в хвостохранилище по десятикилометровому трубопроводу поступали отходы обогащения вольфрамового, молибденового и медно-висмутового концентратов. Около 30 наименований химических соединений металлов, каждый из которых в сильных концентрациях смертельно опасен для здоровья человека и животных. По различным оценкам, с 1966 по 2001 год тут было захоронено от 25 до 118 млн кубических метров отходов.
В настоящее время трубопровод демонтирован, но отходы остаются в озере. Уровень воды в нем поддерживается при помощи сбросного колодца для водопонижения и водоотведения, связанного с водоотводным каналом, соединяющим озеро с Баксаном. Считается, что отходы на дне озера слиплись практически до состояния цемента.
В 2018 году на страницах научно-технического журнала "Вестник МГСУ" группой ученых (К.А. Гегиев, А.Х. Шерхов, З.Ж. Гергокова и К.К. Анахаев) была опубликована статья под названием "Экологические проблемы Тырныаузского хвостохранилища на реке Гижгит", в которой подробно описана опасность, исходящая от бывшего хранилища ядовитых отходов:
"В обогащенных отходах содержатся до 30 наименований химических соединений металлов (в т.ч. высокого класса опасности), которые с поверхности пляжа хвостохранилища в виде пылеватых облаков переносятся постоянно дующими вдоль долины р. Баксан ветрами (Тырны-Ауз в переводе с балкарского языка «ущелье ветров») на прилегающие к ним сельхозугодья и природные пастбища..."
Гижгит — река в России, протекает в Эльбрусском районе Кабардино-Балкарской Республики. Длина реки составляет 28 км. В низовьях запружена, образует водохранилище-хвостохранилище Тырнаузского горно-обогатительного комбината. В самом низовье протекает по искусственному тоннелю до места впадения в реку Баксан. Устье реки находится в 112 км по левому берегу реки Баксан.

We are All Animals, 130 Bloor Street West: We arrive at the forecourt of this condominium to find a family of coyotes waiting outside the entrance. A pup, huddled under its mother, looks toward the street and the park beyond. The other coyotes face away from the park, and toward the building’s entrance: do they want to come in?
But these coyotes are not entirely natural. Their triangulated forms bridge the natural and digital worlds. Do you see the large LED screen near the entrance to the building? This part of the work also focuses on the relationship between the natural and the digital. Powered by gaming software, the digital landscape changes subtly with the seasons. This digital representation of the natural environment sits in conversation with the environment of High Park just steps away across the street. Take a seat on the brass bench, maybe pause to consider the co-existence of ecology, environmentalism and the technology we have created. This bench is inscribed with the name of this work “we are all animals”.
The creators, Public Studio, is the collective art practice of filmmaker Elle Flanders and architect Tamira Sawatzky. The artists are concerned with the personal, social, and political implications of landscape. Public Studio’s multidisciplinary practice often engages themes of political dissent, war and militarization, and ecology and urbanization, through the activation of site.

An estimated $12.95 million worth of wild life animal skins were burned during the 2006 Tibetan New Year festival. Tibetans use animal skin for the decoration of traditional dress.
As a result, millions of dollars worth of animal furs and skins were destroyed as a pledge of sorts. Some say Tibetans in Tibet are advocating a clean environment and loving animals as per the Buddhist way of life.
From an environmental point of view, religion has been a positive and successful force influencing the relationship of Tibetans with their environment. But from other perspectives, religion can be seen as promoting dogmatic behavior with little long-term understanding. The majority of Tibetans have never learned about the environment, nor the ecological science and doctrine behind it. Tibetan Ecology Foundation wants to more deeply explain environmental science to Tibetans and rest of the world by publishing Wild Tibet: Tibetan Mammals and the Landscape of the Tibetan Plateau.

J'ai toujours aimé tirer les goélands, leurs habits gris sont tellement beaux et leur vol est puissant.
I have always loved shooting seagulls, their grey coats are so beautiful and their flight is powerful.
Vine Street Expressway
The street lights around the Vine Street Expressway onramp at 21st St are favorite perches from which the Parkway hawks scan the rodent-rich scrubby verges of the crosstown highway. The field of road ecology, which studies the ecology of transportation infrastructure, was founded by R.T.T. Forman around the turn of the century.

5 exposures of +2, +1, 0, -1 and -2 made up this HDR image.
Used autobracket feature of Nikon D200 (can go up to 9 exposures in one burst).
The HDR treatment I used here is to reveal a realistic image rather than my usual artistic HDR style. Some HDR afficionados call it True Tone HDR or TTHDR for short.
Hope you like it.

Elephants in the San Diego Zoo have a huge enclosure.
Today, seven elephants live in the Zoo’s Elephant Odyssey habitat. Its features include a state-of-the-art Elephant Care Center, helpful, as the herd is made up of older, non-breeding elephants at this time.
They’re enormous and intelligent, strong and sociable. Humans have been impressed by elephants for centuries, simply because they are so big—a male African elephant can weigh up to 7.5 tons (6.8 metric tons)! They also amaze us with their long and flexible noses, large and flapping ears, and loose, wrinkly skin. There are many stories about elephants—you’ve probably heard of Horton, Babar, and Dumbo. Elephants are one of the best-known animals in the world.
Elephants are large and gray and have big ears and long trunks, right? If all elephants seem the same to you, take a closer look. There are two elephant species that are usually recognized: the African elephant and the Asian elephant. There is some ongoing debate about how many subspecies may exist, or whether some of these might, in fact, be species in their own right. Here are a few ways to tell them apart:
- African elephants have large ears that are shaped like the continent of Africa, both males and females have visible tusks, their skin is very wrinkly, their back is swayed, and the end of their trunk works as if they have two fingers there to help them pick things up. African elephants are the largest mammals on land.
- Asian elephants have smaller ears, usually only the males have visible tusks, their skin is not as wrinkly as African elephants’, they only have one "finger" at the ends of their trunk, and their back is dome-shaped.
Empress and Queenie were the San Diego Zoo’s first elephants, arriving here in 1923 via train from San Francisco. After being led off the train, the two Asian elephants refused to move another step, no matter how much encouragement they received. The Zoo’s founder, Harry Wegeforth, M.D., was there to greet them, and it occurred to him that they were probably used to being ridden, so he climbed up on Empress and another staff member did the same with Queenie, and off they walked from the train station to the Zoo, gathering many astonished looks along the way!
Peaches was the San Diego Zoo’s first African elephant—and she made sure to be a memorable one too. When she arrived in 1953, she was three years old, smart, curious, and, as then ZOONOOZ editor Ken Stott described her, “playful as a quarter-ton kitten.” She had made the journey from Africa to San Diego with keeper Ralph “Gabe” Davis, and they got along famously—at least most of the time. When Gabe gave her breakfast, she would grumble and trumpet at him until he left her alone to eat—apparently, she was not sociable in the morning. She also showed a marked preference for men, even pushing away Zoo Executive Director Belle Benchley when she tried to say hello. Peaches did become more mellow as she grew up, but even as an adult, she still had a way of “flirting” with men while more often than not giving women a cool stare.
Since that time, we've had numerous elephants at our two facilities, and our first elephant birth occurred in 1981. In 1971, Asian elephant Carol became famous by appearing on The Tonight Show with the Zoo’s animal ambassador Joan Embery, to meet Johnny Carson and paint for him while millions watched nationwide!
Elephants have been hunted relentlessly for their tusks (even though they’re made of dentine, the same as our teeth). Elephants are now protected, but poachers still hunt them, and they face other problems, too. Because they are so big and need so much food, they can eat themselves out of “house and home.” Elephants and people often come into conflict as elephant habitats undergo dramatic reductions in size. Asian and African forest elephants are listed as endangered, primarily due to habitat loss and fragmentation. African bush elephants are threatened, primarily due to habitat loss and being poached for their tusks.
Elephants Without Borders has been deploying satellite-monitoring collars on elephants throughout northern Botswana since 2000, having tracked over 90 individual elephants; this is one of the longest and largest elephant movement studies in Africa. Every individual pachyderm has its unique character and intriguing story to his or her own seasonal march, preferred routes, and favored places. Each new elephant fitted with a tracking device provides new information to understand the ecology of these animals. Unpredictable individual ranging behavior coupled with a dynamic, ever-changing environment in Botswana underscore the need for long-term elephant studies. The elephants are tracked from a fixed-wing plane, which allows a visual assessment of collared elephants to determine herd structure and habitat use.
Conservation farming project
In collaboration with San Diego Zoo Global, Elephants Without Borders has established a conservation farming project in the Chobe Enclave in Botswana. This project is developing experimental plots with various methods of keeping elephants away from crops, including farming of specific chili species that are thought to be unpalatable to elephants and may deter them from invading crop areas. Along with aerial survey wildlife counts and satellite-collared elephant data, these projects are essential for developing community-based conservation programs to reduce human-elephant conflict and make better-informed conservation decisions for all.

The Ringling Bros. and Barnum & Bailey Circus will phase out the show’s iconic elephants from its performances by 2018, telling Associated Press exclusively that growing public concern about how the animals are treated led to the decision.
