Production is in the region and the local administration, entered into an agreement with the company refers to the fact that this craft creates jobs. Allegations that the seals violate state fisheries can not withstand scientific criticism, say environmentalists. Nowhere is there is no serious evidence that culling Seals is a way to protect fish resources. According to fishermen, due to depletion of fish stocks are excessive fishing, oil spills and dumping of toxic waste. On the contrary, the seals consume predators that prey on fish, fishing, and their destruction leads to a decrease in its quantity.

Commercial hunting and poaching have put some species of the family seal on the brink of extinction. For example, now very quickly declining stock of ringed seals as a result of uncontrolled harvesting and water pollution by industrial wastes. Scientists have found an animal that can survive in space, Swedish scientists have proved that living organisms known as tardigrades, are able to survive in open space. Tardigrades belong to the arthropod animals of up to 1.5 mm in length and are considered the most enduring form of life on Earth. Tardigrada prefer moist conditions and at during the dry period fall into a state of suspended animation. Thanks to their endurance they are spread almost everywhere. Tardigrada in the experiment were sent into Earth orbit and conducted in open space about 10 days, experiencing the impact of cosmic radiation, low temperatures and pressures.

At the end of the experiment almost all the animals were seared, but the spacecraft, due to its unique biological mechanism to re-establish their life functions and even been able to reproduce offspring. How tardigrades survived in open space, biologists still unknown. Perhaps these animals are capable of restore the structure of dna, broken the influence of hard ultraviolet radiation. Understanding of how living systems are able to defend themselves against the damaging effects of space, is an important development astronautics. Zoologists for the first time managed to take pictures of the okapi in the wild cameras installed by specialists Zoological Society of London in the Democratic Republic of the Congo National Park Virunga, photographed a rare animal is the okapi in its natural habitat, which is a unique case. Okapi are very rare and shy, so getting pictures of these animals in the wild is almost impossible. Okapi was unknown to the Western world until the early 20 th century. Last okapi officially observed 50 years ago. In 2006, experts of the World Wildlife Fund (WWF) have found traces of an okapi in the west bank of the River , it the northern sector of Virunga National Park. There are currently three areas of their habitat, they are protected. Virunga National Park, where photos were taken, is one of those areas. Okapi – a rare cloven-hoofed mammal of the family of giraffe, the body length is about two meters in height at the withers to 1.2 meters, weighs about 250 pounds. On the forehead of two short horns. Variegated coloration: head light with dark markings, body grayish-brown, cereal and limbs – with alternating white and dark transverse stripes like a zebra. Okapi live in Africa, in tropical rain forests of the Congo Basin. Okapi can be met so rarely that a long time These animals were considered mythical

Such a way as the main threat at the moment – the melting of glaciers on planet. But British researchers conducted another study – they have found new evidence that solar activity has no effect on climate change on the planet. They could not find a connection between solar activity and global climate change. Thus, they questioned the theory about the influence of cosmic rays, launched by the Danish scientist Henrik Svensmark, who says that the intensity of cosmic rays depends on solar activity. If research scientists from the University of Lancaster are confirmed, the main factor stimulating global warming, will be considered by human activities, specifically the huge emissions of greenhouse gas emissions worldwide. Sochi Olympic facilities again 'gunpoint' And again, the Olympic venues of the capital the 2014 Olympics were in the sights of activist environmental organizations. For example, Greenpeace last week announced that they are currently considering the possibility of appeal to the court against the International Olympic Committee (IOC) of gross violations of environmental regulations in preparation for the Winter Olympics in Sochi. But the concrete requirements have not yet been formulated.

However, it is possible that it will demand the abolition of the decision to hold the Games in 2014. World Wildlife Fund (WWF) also continues to insist on transferring the bobsleigh track in Sochi construction of which will affect the Caucasian Biosphere Reserve, an area of Polyana. The head of the Russian branch of wwf Igor Chestin said that now the position of environmentalists to move the tracks already supported by the Ministry of Natural Resources of the Russian Federation and the sc itself 'Olympstroy', which is engaged in construction of infrastructure and sports facilities in Sochi.
