D i ox i n s a n d f u r a n s i n t h e atmosphere. Their impact on humans and nature. Emission sources What are dioxines and furans? The term Dioxin is commonly used to refer to a family of toxic chemicals that all share a similar chemical structure and a common mechanism of toxic action. Most dioxins and furans are not manmade or produced intentionally, but are created when other chemicals or products are made. This family includes: seven of the polychlorinated dibenzo dioxins (PCDDs), ten of the polychlorinated dibenzo furans (PCDFs) and
born. ( EX: infant's reaction to heights ) The visual cliff- an infant is placed on the center board of a heavy sheet of glass and his mother calls to him. If he is the deep side of the cliff, he will not crawl across the apparent cliff.This suggests that the perception of depth is not learned through experience, but is built into our system at the very start. Complex social behaviour in humans: human social interactions are more subtle and flexible than those of animals. For much of human social life is based on the individual's rational appraisal of how another person will respond to his own actions: ,, If I do this...he will think this...then I will have to do this.." and so on. Peacockss courtship ritual happens to fail then he has no alternate strategy; all he can do is display his tail feathers again and again.
Protecting endangered species will make a difference in humans' life In the nature of humankind it is natural to hunt animals. However, nowadays hunting endangered species will make humans be just killers, because it is not necessary to kill something just to have a trophy on the wall at home. People can be proud of what they have done, but decreasing the population of a species largely will cause the specific animal breed to go extinct faster than it would happen via natural causes. Therefore, humans should stop hunting endangered species to slow down their extinction, as these species offer balance in the wildlife, are used without purpose in medicine, and may
Banning smoking Smoking is very harmful to humans, but young people do not think about it much. The smoke is many harmful substances that destroy the human body. Young people who smoke do not think about what awaits them in the future .Each smoke, they pulled by damaging their body. Smoking is harmful to humans. The smoke contains many toxic agents. Smoking causes all sorts of horrible diseases - which can be fatal. Usually young people begin to smoke mostly out of boredom or large nervous tension. Many young people also want desperately to quit, but they will not be able to the more so because the body is accustomed to smoke too much, and if they can not reach your collection they become nervous. Smoking damages the nerve cells.
Human nature exposed in G.Orwell's ,,Animal Farm" Humans are the most deceitful animals in the World. Even if we do not want to confess it to ourselves, we have to accept the fact that humans constantly change their ways of thinking and acting to make the World a better place to live in for themselves. Our lives are fulfilled with lies we enter to our or someone else's mind. A lot of it is connected to people's constant need of power and control. "Animal Farm" is a book that reverberates that kind of human nature through politics, dictatorship and power, but in nowadays' World this kind of behaviour occurs also in our everyday life, not only politics.
The Future of Work Automation anxiety has been spreading lately. What's clear is that there will be significant change. What's less clear is what that change will look like. The threat of technological unemployment is real. A picture that we see on our television screens, in everyday commentary is one where an army of robots descend on the workplace with one goal in mind: to displace humans from their work. Yes, machines displace humans from particular tasks, but they don't just substitute for humans. They also complement them in other tasks. Sometimes they complement humans directly. So a taxi driver can use a satnav system to navigate on unfamiliar roads. It also complements humans indirectly and it does this in two ways. Think the economy as a pie. Technological progress makes the pie bigger. As productivity increases, incomes rise and demand grows. People displaced from the
According to the common thought, people decide to keep pets for many reasons. Firstly, a lot of old people keeps a pet at home to feel less lonely and to have a companion in their everyday life. Pets keeps occupied a lot of time of their days, doing things such as taking the pet out for a walk or play with them. Moreover, families too choose to have a pet in their lives for many reasons, for instance having their baby feel a lot more confident with animals. Historians don't know for sure when humans started keeping pets. Dogs were one of the first animals domesticated by humans and have been domesticated for some 10,000 years. According to ancient Egyptian law, taking the life of a greyhound warranted the same punishment as killing a man. As early as 3500 B.C., Egyptians were domesticating wildcats from Africa. They considered cats to be godesses pets. That ranked them above humans, making them the first to be saved if a house caught fire, before the people.
such as modern medicine. But is that all that defines us? In recent years, many traits once believed to be uniquely human, from morality to culture, have been found in the animal kingdom (see part one in this two-part series). So, what exactly makes us special? The list might be smaller than it once was, but there are some traits of ours that no other creature on Earth can match. No animal can get close to the devastation humans can cause (Credit: Thinkstock) No animal can get close to the devastation humans can cause (Credit: Thinkstock) Ever since we learned to write, we have documented how special we are. The philosopher Aristotle marked out our differences over 2,000 years ago. We are "rational animals" pursuing knowledge for its own sake. We live by art and reasoning, he wrote. Much of what he said stills stands. Yes, we see the roots of many behaviours
And this can bay back very hard. For example the event what took place in Kauhajaki school, where one young guy named Juhani Saari, who killed very many his fellow pupils and himself too. This disaster took place because other pupils taunted and japed him. Religion is in the 21st century very disunited. This makes society acceptive to every little suasions. At the same point education is very easy to get. And when some malevolent human studyes psychology, can he or she manipulate whit other humans and that way he or she can create his or her new religion. And the end of this religion could be very tragic and it could end with very many deaths and suicides, just because somebody tells it is the only right way. For example in the Guyana jungle were founded 914 corpses. They were reverend Jim Jones commanded Folks Temple sects members. Jim Jones used academic psychology to manipulate with them. Abnormal freedom of speech gives in economy big opportunityes to cause a big changes. For
Kafka's Hunger Artist Kafka, in his masterpiece "The Hunger Artist," suggests that humans can never satisfy their desires. This is illustrated through the metaphorical hunger artist for whom nourishment is not being nourished at all. The viewing public's interest is derived from their desire to see the hunger artist cheating, but to view this would put an end to that desire. Finally, Kafka presents this idea while the artist is at the circus and describing when people wish to view the starved man. The hunger artist's nourishment is spiritual
The pollution of water kills hundreds of thousands of water animals and birds. Some of the big companies have accepted the problem and are taking action. For example McDonald`s and Burger King are not using plastic straws anymore. Second thing that affects the life on Earth is overpopulation. The estimated population in 2050 is near 10 billion. Population growth also raises overconsumption. People are encouraged to consume by companies and their commercials. The problem is that humans are consuming more than the Earth can regenerate. The exhaustible resources are running out. And with the population growing, it will become an even bigger probleem. This means people in the future may not have enough resources, because right now humans are using too much. Another huge problem is global warming. The effects of global warming can already be seen today. Half of the Great Barrier Reef already dead because of the increasing temperature.
Sheep senses and social cognition Sheep generally are held in low regard as far as cognition and social skills are concerned. However there is now interesting evidence from studies of their behaviour and brain function that they have highly sophisticated social and emotional recognition skills using faces, voices and smell. They are able to recognize and remember many diferent sheep and humans for several years or more and appear to have some capacity for forming mental images of the faces of absent individuals. The precence of such social cognition abilities in this species means that we must pay careful attention to welfare factors such as the composition and stability of their social environment as well as the nature of our own interactions with them. To many humans sheep are regarded as being as close to an automaton and amindless animal
Pros and Cons of Technology Humans are developing technology every day. What are the benefits and risks that technology can cause to humanity? There are a lot of different fields of technology. It is hard to find a profession where people do not use technology. Thanks to technology, we can make much more work during the day, for example a car, we can get from one town to another much faster with driving than walking. Althought it is good and comfortable for humans, it is not good for the air we breathe because of the exhaust fumes. This is the example to my belief that every technology have pros and cons at the same time. Year by year people are getting used to get their work done by or with technology, that is why i think we may get lazy and do not value what we have to do to get something done. Technology helps us to live longer. Our medicine is on whole next level than it was a century ago. I am sure that in future our average age will raise.

The Pros and Cons of Vegetarianism Vegetarianism is getting more and more popular nowadays. The most popular reason why people start being a vegetarian is because of health. They say that humans do not need so much meat as they eat. According to some experts vegetarians live six to ten years longer than meat-eaters. Nature offers us an enormous variety of fruits and vegetables, they have some or all the following: vitamins, minerals, proteins, fat, water. A well planned eating plan can provide all those things you need in a meal. Vegetarianism helps maintain weight, changes that a human is going fat with vegetarian lifestyle are very less
has the highest average elevation of all the continents. The coldest natural temperature ever recorded on Earth was -89.2 °C at the Russian Vostok Station in Antarctica on 21 July 1983. Antarctica is also extremely dry, technically a desert, whit an average of only 166 mm of precipitation per year. Population of Antarctica The number of people conducting and supporting scientific research. The number of people varies about 1,000 humans in winter and to about 5,000 humans un the summer. Many of the stations are staffed yearround, the overwintering personnel typically arriving from their home countries for a oneyear assignment. Emilio Marcos Palma was thr first person born on the Antarctic mainland in 1978. Geography of Antarctica Antarctica is divided in two by the Transantarctic Mountains close to the neck between the Ross Sea and the Weddell Sea. The three largest mountain ranges on the Antarctic continent are the Transantarctic
Religion did not let science to evolve, but thanks to the sciences like Galileo Galilei science evolved because he was brave enough to say that earth is not the centre of the world. 2. Truth always comes out, Crusade wars began because of Turks conquered the holy lands and mistreated the Christians not because Christians wanted to increase their religion that happened later after the Crusade wars. 3. The Bible put humans to believe that we all are Childs of Adam and Eve but in fact humans evolved from apes and the truth helped the science to find the real origin of people. 4. Many people say that they have seen UFO-s but most of us do not believe them and the truth of alien existence may hide behind area 51 who have hidden many facts and proofs of UFO-s. 5. The war in Afghanistan is pointless but Americans don't want to see the truth that Russians lost the war
Animal Experimentation Based on the Constitution of Estionia, we are all born with equal rights. However, mankind denys that animals share these rights. Animals are just as entitled to the rights of living, avoiding pain as humans are. Nonetheless, we still abuse them, often even without a second thought. Despite the wide use of animal testing, the research gained from it is not helpful to mankind. The chemicals and medicines tested on animals reacts differently on every species. That is why results gained from animal testing could be incorrect and misleading. In many cases, not only are the results wrong, but the opposite can be true for humans; a drug may
Class essay. Music is the Universal Language. Music is everywhere around us.. it is in the wind when it blows.. birds, who are loudly screaming now. The noise of cars.. the noise of humans, expecialli their laughing makes me a little happier everytime when I hear it. There're such beautiful voices. Sometimes we just must stand quiet in center on those voices, and catch their message. Music tells us stories wich were never known. Nowadays young people hear music on MP3. They're like in their own reality. Yes it's great to feel that, but a little bit strange, because when somebody wants to ask something at the bus stop, they can't hear anything. Thats sad
11. kl Destroying Angel 0 Commonly referred to as the Destroying Angel, Amanita virosa is a deadly poisonous fungus. The Destroying Angel is more plentiful in mountainous areas and grow in or near the edges of woodlands. They can also be found on lawns or grassy meadows near trees or shrubs. 0 Destroying Angels usually appear in July, August and September. Immature specimens of A. virosa resemble several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Description of Destroying Angel 0 Caps of the Destroying Angel are 5 to 10cm in diameter, pure white, and without any marginal striations. The cap is initially egg- shaped or occasionally almost flat. Amanita virosa gills are white, free and crowded. 0 Stems of Destroying Angels are 9 to 15cm tall and often slightly curved; pure white and fibrous with fragile ring high up on the stipe. 0
Being normal components of intermediary metabolism, neither formaldehyde nor formate are stored to any significant extent in any tissue of the body. Formate is excreted in the urine (primarily as formic acid), incorporated into other cellular molecules, or oxidized to carbon dioxide and exhaled. Formaldehyde vapors are readily absorbed from the respiratory tract. Due to rapid metabolism to formate, little, if any, intact formaldehyde can be found in the blood of humans or animals exposed to formaldehyde. Formaldehyde is also readily absorbed from the gastrointestinal tract and meets with the same metabolic fate as formaldehyde after inhalation exposure. The studies available in the open literature suggest that very little formaldehyde is absorbed via the dermal route. In all cases, absorption appears to be limited to cell layers immediately adjacent to the point of contact. Entry of formaldehyde into the blood (i.e
An adult can weigh up to 200 pounds. It is the second heaviest cat in the New World, after the jaguar, and the fourth heaviest in the world, after the tiger, lion, and jaguar, although it is most closely related to smaller felines. Cougars are good climbers and can leap more than 20 feet up into a tree from a standstill. They can jump to the ground from as high as 60 feet up a tree. A single male lion may travel 25 miles a night while hunting. Cougars may be active by day in areas far from humans. They are most active at dawn and dusk, the times when deer are out feeding. In a healthy ecosystem, Mountain Lions are a top predator, helping to balance wildlife populations. Deer are their primary food sources, and the presence of deer indicates likely presence of cougars. Mountain lions are opportunistic feeders, and can survive on a variety of prey including rodents, birds, porcupines, fish and raccoons, as well as livestock and domestic animals.

The name itself refers to the exact reason we are special our mental capability. What does ability to think give us and how does it affect out world? Human is a social being and cannot live without expressing himself. In order to communicate clearly we have developed a vast system of symbols languages. There are over 6000 different languages in the world and each language comes with a different culture. Because of our ability to remember, humans are able to transmit information from generation to generation. Humans know their history, because we remember what we have created. Our world-view is more than what is seen to the eye. Homo sapiens is a developing species. Our body has changed and so has our mind. We understand concepts like time (past, present, future), religion, philosophy and moral behaviour. A human is curious, asks questions and finds answers. Unlike animals, we are conscious of our inner thoughts, desires and sensations
Something out of nothing. Why do people enjoy making something out of nothing? I believe that it gives us great pleasure to know, that we've made something new and interesting just because we're humans. We like to feel big and important, it's just our nature and we can't help it. For example, many people believe in God. They believe God is always watching over them, so they have to behave, because noone wants to be on the bad side in the eyes of God. And ofcourse everyone wants to go to heaven, so you can't really get on God's nerves, or he'll just send you to hell. The way I see it, God makes all the rules and you can't really argue with him, because he's God. He

Homelessness Every night thousands of people are on the streets. This type of behavior is considered deviant because it does not reflect the norms and values of our society. In many cases the homeless people in our country are treated as total outcasts. Many of these people have severe mental disorders. Some are victims of an economy that has failed them. The homeless are in need. As fellow humans we are obligated to help those in need. They are not only in need of money, but they are also in need of our attention and our support. In the past fifty years the United States has invested more money in helping the homeless people than any other country in the world. The result is that we have more poor people now and more people dependent on the government than we did fifty years ago. The welfare program in our society has failed
Retelling the Aboriginal people 1. The formation of the continent Australia, a continent of geographic and biological diversity (mitmekesisus), has an amazing range of animal and plant life, as well as one of the world's oldest ethnic groups. After the last Ice age, when sea rose considerably (märkimisväärselt kasvanud), Australia and its largest island Tasmania, became isolated form the rest of Asia. 2. The earliest inhabitants The earliest humans living in Australia are called Aborigines and they are descended (pärinevad) from among the earliest humans in the world. For thousands of years Aborigines lived as hunter-gatherers along the coast and in the inland desert areas, following the same lifestyle as their ancestors. 3. Finding food and water Aboriginal tribes obtained water from trees and roots and even squeezed water out of the bodies of frogs. Women collected anything that grew or moved, including fruit, lizards,
back, rump and the base of its tail, which earned the animal the nickname “tiger". • Its body hair was dense and soft, up to 15 mm (0.6 in) in length; in juveniles the tip of the tail had a crest. Extinction in Australia • The thylacine is likely to have become near- extinct in mainland Australia about 2,000 years ago, and possibly earlier in New Guinea. • The absolute extinction is attributed to competition from indigenous humans and invasive dingoes. • Humans had an adverse effect on the environment and brought disease to Australia that their arrival drove the thylacine to extinction. Extinction in Tasmania • Although the thylacine was extinct on mainland Australia, it survived into the 1930s on the island state of Tasmania. • The Van Diemen's Land Company introduced bounties on the thylacine from as early as 1830, and between 1888 and 1909 the
Books have been our mates many centuries. They give you a lot of knowledge, they make you feel happy, but sometimes also sad too. If you have read any book through, one is certain your life is not the same anymore as it was. So, a question comes to my mind if books are material things, they can not speak, they can not do anything to you, they just lay on the table, then how they can influence your life sometimes so much? They are all written by humans. But the interesting thing actually is, that in his lifetime, human being is the smartest on this planet and can make big things, but this is all transient. Humans die. But if human creates something, for example, a book, then it may live centuries. Books are like the continuation of the book writers life. Human's mind can forget, but if the book is in the bookshelf and your name is on the cover, then it will not disappear anywhere. You may "live" thousands of years.
Influences- Tales about werewolfs, vampires, dragons, arcangels have been told hundreds years before the first otherkin community was founded. It is obvious that these stories and strange events connected to these stories influenced the appearance of real vampires and half-unicorns but there comes the question- where were the otherkins two hundred years ago? Or why did they firstly appear only 20 years ago? Well, it is believed that non-human humans always lived on the planet, thruout the history but only in 1990-s they had a chance to talk about themselves, after the World experienced so much- two world wars, genocide etc. Only then could the otherkins talk about themselves without a fear of being bullied. First big otherkin community grew out of the elven online communities of the early-to-mid-1990s. The oldest Internet resource for otherkin is the Elfinkind Digest, a mailing list started in 1990. It was the time when
But...oh!" And a deep cry filled with hopeless despair filled the air. The man remembered about the fire and said, "I could help you I`m one of the Royal Soldiers!" But the woman became even more sad and said, "I am a human myself, just like you, but when I was 7, evil monsters called the ishues came to our city city La Air it was then as I remember..." "Wait!" interrupted the man, "You mean these "ishues" or what-so-ever aren`t just normal humans?!" The woman burst out laughing and her baby cried even louder by now. "Humans? NORMAL HUMANS?" she shouted nervously, "The ishues are pure demons! Even the prays can`t keep them away! We tried everything we could: starting with building more and more once holy and pure churches like this one was then and finishing with..." But the woman couldn`t finish her story because one side of the roof had fallen on her. The man was covered in dust and so was the baby that the poor woman had
I slaid I am going to talk about strange animals that live in Australia. II slaid Australian kangaroos are the most famous Australian animals, and they belong to the most recognisable icons in the world. Australians call them 'roos' and they can be found in all parts of Australia, not just in the Outback. Their young are called joeys. All kangaroos are herbivores and only eat plants. The biggest enemies of kangaroos are humans. III slaid The Koala is one of Australia's best known animals. It is an icon represented when promoting Australia to the tourist industry. Koalas are mainly found in the south east Australia. Koalas are often referred to as a Koala bear. However they are not a bear. The name Koala comes from an Aboriginal word. It means "no drink", as Koalas get enough fluids through the eucalyptis leaves they feed on. They do not move around much and are only active for about 2 hours of the day. IV slaid
Something was wrong with him too. He was scared and frightened. His hands were sweating and he had pale look on his face, like he had seen something creepy. „What’s going on? Why’s everyone outside? Why is the rainbow so different?“ I asked him. My friend didn’t answer. Suddenly I heard something strange. The city gates opened and an army of monsters came in. They were all dressed in black. They had big teeth and they were carrying swords and gems. They had a very similar faces to humans, but something was different. They had tales. I couldn’t understand whether they were humans or animals. I was really scared. Suddenly they shot my friend. I was shocked and I couldn’t believe my eyes. People ran away screaming, some even fainted. I was upset and didn’t know what to do. I closed my eyes for a second. Tears fell down on my face and I asked myself: „Did I really just see, how my best friend died?“ I knew that I had to take myself together

. This is like someone is sitting in your room and making notes about your likes and dislikes. The things we search online, personal things, are stored in the ,,big data" possibly forever and are available to researchers in the futuure. Google, ,,hungry" for data, confessed that they know pretty much every WiFi password in the world. Of course they can not access to this data when ever they want, but they do store this sensible information, In the end, maybe humans stop to be humans all together because we do not have to think anymore, just open Google and this will predict our wishes. I really like how Julie Cohen describes that The "smartest guys in the room" no longer work for Enron, Lehman Brothers, or AIG, now they work for Google or Target or Acxiom, pursuing the holy grail of knowing customers better than they know themselves". This is pretty much the same with politics, government uses networks to identifying and targeting

October 1906. It is the story of a wild wolfdog's journey toward becoming civilized in Yukon Territory, Canada, during the Klondike Gold Rush at the end of the 19th century. White Fang is a companion novel to London's best-known work, The Call of the Wild, which cares a kidnapped civilized dog turning into a wild animal.Much of the novel is written from the view-point of animals, subject to London to explore how animals view their world and how they view humans.

We were able to produce food crops for our consumption and for trade/sale successfully even before photosynthesis was discovered and therefore we don't find it as valuable. When we compare photosynthesis to the discovery of the double helix in DNA structure which has helped scientists identify genes that trigger diseases and manufacture drugs for those diseases, it is safe to say that DNA discoveries are much more valuable to us, the ordinary people, as they can save humans lives, whereas learning about photosynthesis doesn’t. The scientific community might, however, find information about photosynthesis very useful and valuable nonetheless. Ethical knowledge is valuable though often times easily produced. Different people have different perceptions of what is ethical and what isn’t. We do heavily rely on common and widespread ethical beliefs, but our personal ethical beliefs are essentially what we act upon
The size of the frog may vary from 1.5 centimeters to 6 centimeters. Some poison dart frogs weigh as less as 2 grams and are about the size of a paper clip. Their colouring can be yellow, gold, copper, red, green, blue or black. Colourful skin is very appealing yet venomous. Dart frog venom These frogs some species are absolutely lethal. Poison dart frogs keep their poison in their skin and this can kill anyone that touches them. The golden poison dart frog has enough venom to kill 10 adult humans. Only two micrograms of all dart frogs venom is enough to kill a large mammal. Other facts Only some predators like certain spiders and the Amazon ground snake seem immune to the poison dart frog toxins. Frogs get poison from animals which they eat. Medical have already developed a synthetic version of one compound that shows promise as a painkiller.
ARCTIC WOLVES ARE SMALLER THAN GREY WOLVES, THEY ALSO HAVE SMALLER EARS AND SHORTER MUZZLES TO RETAIN BODY HEAT. GREY WOLF ARCTIC WOLF HABITAT AND DISTRIBUTION • They have lived in North America for more than two million years. • The arctic wolf inhabits the Canadian Arctic and the islands, parts of Alaska and northern parts of Greenland. • In their natural habitat, they rarely encounter humans. MAIN THREATS • The greatest threat to the Arctic wolf is climate change. • Extreme weather variations in recent years have made it difficult for populations of muskox and Arctic hares to find food, and this has caused a decline in numbers. CLIMATE CHANGE THANK YOU FOR LISTENING!
