Environment al art Marika Rodionova 11a What is that? The term "environmental art" often encompasses "ecological" concerns but is not specific to them. It primarily celebrates an artist's connection with nature using natural materials. The concept is best understood in relationship to historic earth/Land art and the evolving field of ecological art. The field is interdisciplinary in the fact that environmental artists embrace ideas from science and philosophy. The types Ephemeral - made to disappear or transform Designed for a particular place - and can't be moved Involves collaborations between artists and others, such as scientists, educators or community groups What is the point? Informs and interprets nature and its processes, or educates us about
system and to what extent the aquatic ecosystem is maintaining that population. Depending on the type of stream visited and the field chemistry and habitat measurements taken, biologists have certain expectations of what type of species they should expect to find. When this ends up not being the case, as where warm water pollutant tolerant species are found in what would be considered cold water species habitat, then the biologists look closer into possible causes for the ecological imbalance. When combined with water chemistry, habitat, and stream invertebrate information, a clear picture of the ecological system is brought in to focus from which sound management decisions can be made. 8.1 Introduction · Electrofishing - use of electricity to: capture fish guide fish block the movement of fish Elektripüük öösel http://www.fisheries

Kuna inimene kuulub samuti viimase astme tarbijate hulka, siis kogunevad mürkained ka meie kehadesse, põhjustades näiteks vähki, viljatust või maksahaigusi (Kislenko et al. 2009). Toiduahela kontsentreerumise süsteem on iseenesest väga lihtne: pestitsiidid pritsitakse kahjurite tõrjeks põllumaale, kus nad satuvad maapinnale ning pääsevad mulda. Koos vee ja mineraalsooladega imenduvad pestitsiidid taimedesse (Introduction to ecological pyramids: biomagnification. Accumulation of harmful chemicals in food chains. 2010). Sellega on pestitsiidid toiduahela esimesse troofilisse tasemesse sisenenud ja pannud aluse biomagnifikatsioonile ehk bioloogilisele kuhjumisele (Miller & Spoolman 2008). Antud taimi tarbivad taimtoidulised organismid, mida tarbivad järgmise troofilise taseme organismid ja nii jätkub süsteem toiduahela viimase lülini. Igas troofilises tasemes on kogunenud organismi järjest

evidence for this view with a rotating hollow mask, where the mask can be seen hollow or normal. The assumption being selected is strongly influenced by past experience of faces. According to Gibson's view of optic flow where the perception is seen as a result from interaction with the environment and also within movement it is possible to perceive that the mask is hollow. Therefore a weakness of Gregory's´ theory is that it lacks ecological validity because it does not focus on everyday perception, but rare `abnormalities of perception'. Evidence for Gregory's view comes from demonstrations and visual illusions showing that conceptual knowledge affects the way in which simple visual phenomena can be perceived. Nevertheless, it does not explain how the knowledge for perception is acquired. In contrast Gibson has an alternative explanation with texture gradient and affordances.

They have also proposed a large tally of quintessentially nature-friendly, farming practices. As a trained economist with advanced degrees in both agricultural and forest economics, he is able to take the next step; that of presenting agroecology as a fully-fledged science complete with its own economic underpinnings. And so he wrote book called ,,Agroecological Economics", which I think is his life-work. Book review Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. Agroecological economics, a subsection of agricultural economics, evaluates the ecological consequences of agricultural methods on the economic scale. Agroecological economics considers green engineering is the best way to produce products. Agroecological Economics analyzes the current topics that must be addressed in order to provide sustainable agricultural systems

What Is a Healthy Lifestyle? A healthy lifestyle is one which helps to keep and improve people's health and well-being. Nowadays our life is getting more and more tense. People live under the press of different problems, such as social, ecological, economic and others. We need to be healthy to cope with the demands of daily life. But what does it mean to have a healthy lifestyle? To have a healthy lifestyle, we must eat a variety of healthy food most of the time, get regular exercise, have time to relax, give up all our bad habits, get adequate sleep. Food is a key element of our good health. Eating healthy, nutritious and vitamin-rich products can improve your health.

The ecological footstep of mankind is getting bigger and bigger by the day. Although everybody seems to acknowledge the problem and also care about the wellbeing and preservation of our planet the situation is only getting worse. Firstly, the ever growing need for energy is taking its toll on the environment. Due to the fast growth of the economical and industrial sector in recent years the need for energy has grown dramatically. Global warming which is responsible for the melting of the ice cap which leads to the rise of sea level is mainly caused by the high use of fossil fuels. Secondly, over-consumption caused by population growth on Earth leads to pollution which is becoming highly dangerous to the environment. The decomposition of materials used nowadays is often hundreds of years long. Unfortunately the number of reusable products is getting smaller by the day. Often the reusable product is also less affordable to the consumer wh...
native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak bear, which is approximately the same size. A boar (adult male) weighs around 350 700 kg (7701,500 l while a sow (adult female) is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Although most polar bears are born on land, they spend most of their time at sea. Their scientific name means "maritime bear, and derives from this fact. Polar bears can hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present.

Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution. Virtually all types of water pollution are harmful to the health of humans and animals. Water pollution may not damage our health immediately but can be harmful after long term exposure. Such as the water pollution is global ecological problem we have to know what can we do to prevent this contamination and how to keep waters clean. There are many things we can do to help. We have to be careful about what we throw down our sink or toilet. We can't throw paints, oils or other forms of litter down the drain. By having more plants in our garden we are preventing fertiliser, pesticides and contaminated water from running off into nearby water sources.
Moving from city to country has been the traditional path for those in their 30s and 40s, particularly if children are involved. Nowadays flat rates in cities can be more expensive than living in a house in the countryside. Therefore, living in the countryside can be more affordable. In addition, the countryside is generally quiet and peaceful without the toxic polluted water and air. Some people prefer to live in the country for ecological reasons. For example, eating home- grown or locally grown food may easily become a part of lifestyle. Some people even raise their own animals. Accordingly, because cars are not idling in traffic there is less smog. However, there are some negative aspects of living in the rural area. For some, the lack of entertainment and smaller community is the biggest turn-off. Others are concerned about distances between two points, especially if an accident has happened and medical care is needed.

If we look at the landfills we can see how full they are. I think it is that way because we produce too much and use too much packages. We should produce only as much we really need or in the future a really big part of earth would be covered with trash and air full of smog and acid rain. Also we should think some reusable way for packaging. Thirdly we are not thinking what we do with our everyday behaviour to the future. Almost a week ago we took a test, which showed how many planets is your ecological footprint. Mine was 3,22. It shocked me and after that I have started to think more about easy things we can do often. Like turning the water off while brushing your teeth, driving less with your car. Also before a trip I have never taught, what flying with an airplane does to the environment, next time I will. For conclusion I think we should think more about the future of our planet. We should waist less
maastike kaitse Viimastel aastakümnetel on üha enam hakatud tähelepanu pöörama elupaikade ja kasvukohtade kaitsele. Eestis võib metsade ja rabade pindala vähenemine kaasa tuua must toonekure ja kotkaste kui liikide kadumise. Ürgilmeliste metsade pindala vähenemine ohustab tugevasti lendorava püsimajäämist Eesti faunasse. Eestis on aktiivselt toetatud üle Euroopalise kompensatsioonialade võrgustiku kujundamise ideed European Ecological Network, EECONET. Liikide kiire väljasuremine ohustab inimkonna heaolu Bioloogilises mitmekesisuses toimunud muutused on viimase 50 aasta jooksul olnud suuremad kui kunagi varem inimajaloo jooksul. Liikide hävimine vähendab ökosüsteemide poolt inimeste heaolule ja keskkonnale kaudselt mõju avaldavaid positiivseid tegureid. Bioloogilise mitmekesisuse kahanemine jätkub või isegi kiireneb.

distribution of new pathogenic bacteria and also to increase the number of people who are suffering from food allergies. Some grades of transgene plants perniciously affect wrecker organisms and, as a result, they affect helpful organisms too. The possibility of escaping of an alien gene in the wild nature is not excluded, and it is difficult to submit what consequences can be. But it is clear that genetic pollution is capable to break natural balance and to lead to the ecological disaster which consequences can be much more dangerous than chemical and radioactive pollution. All things concidered, I think, that genetic engineering can be very helpful, but it is needed to make more researchers to prevent mutagen changes, which can be harmfull for human. If genetic engineering becomes more safe, many problems of humanity will be solved.
It is also in underground and, naturally, in the air. Even clouds consist of water steam. People, animals and plants couldn´t live without water. Their bodys contain more than a half of water, they need water constantly. Thirdly soil, which is the surface of all continents. The soil on the Earth is not the same fertility. Some places are covered by different plants and some are not, imagine a desert, where isn't growing anything. I'm sure you know there are many ecological problems today. It is the pollution of seas and oceans, dissapearance of many species of animals and plants, acid rains, destruction of the ozone layer and etc. In spite of this, people are still harming the enviroment. The great number of cars contribute much to the air pollution. Many factories are built near rivers into which they put their chemical waste. Amounts of industrial and city waste are placed near the lakes and rivers.

European Union economic 9th May 1951, six Western-Europe countries (Belgium, Italy, Luxembourg, Netherlands, France and Germany) signed a treaty to run their heavy industries coal and steel under a common management. From this economic cooperation agreement, European Union has grown up. For today, the aim of this union has made 180º turn but the reason why more and more countries are joining it is still same to rise the economy. So how does it work? European Union is functioning like an independent country. It collects taxes to reach its objectives. Taxes are collected mainly from member countries GDP (1,1% of countries budget) but as well the import duties on good bought into EU. Also, every member country is paying 0,1%-0,33% of their VAT (value added tax). It is the way how EU gets its budget which is about 120 billion per year. This money is spent mainly to improve agriculture (direct aid, export refunds, sto...

Gestation Period: 9 months Young per Birth: 1 Weaning: After 6 months. Sexual Maturity: Females at 15-36 months, males at 4-5 years. Life span: Up to 25 years. Primarily nocturnal, Giant Elands are highly nomadic, with large home ranges and seasonal migration patterns. During the day, herds often rest in sheltered areas. A gregarious species, Giant Eland herds usually consist of twenty or more animals and do not disband during the wet season, suggesting that social rather than ecological factors are responsible for herding. There is no evidence of territoriality, and males rarely display aggression, even during the breeding season. Giant Eland are alert and wary, making them difficult to approach and observe. They move quickly, running at over 70 km/h (42 mph), and despite their size are exceptional jumpers, easily clearing heights of 1.5 m (5 ft). Giant Eland live in open forest and savannah where they eat grass, leaves, and branches. Their

Technology and I´m standing here in front of you to talk about the ,,passive houses I will inform you about their magnitude and percentage nowadays and also talk about the potential difficulties that might appear when building a passive house". But I´ll start off by giving you an overview of the term. The definition of a passive house is based on its extremely low energy need. Passive houses consume less than a quarter of energy required for a standrard building, as a result reducing its ecological footprint. So it´s a ultralow energy building which requires little energy for space heating or cooling. Sounds appealing right? Sustaining the earth for our future generations and also in the long run benefit from living there with paying lower taxes. However sadly, nowadays there is known to be only up to 20,000 passive houses world-wide out of 1,6 billion households. Which leaves us only 1 house out of 80,000. So why such shocking figures?
(dipliitid). Another 52% is fully exploited, these are in imminent danger of overexploitation and collapse (kollaaps). Therefore a total of almost 80% of the world's fisheries are fully to over exploited, depleted, or in a state of collapse. Worldwide about 90% of the stocks of large predatory fish stocks are already gone. In the real world all this comes down to two serious problems. We are losing species as well as entire ecosystems. As a result the overall ecological unity of our oceans are under stress and at risk of collapse. We are in risk of losing a valuable food source many depend upon for social, economical or dietary reasons. FISHING DOWN THE FOOD WEB: It's not only the fish that is affected by fishing. As we are fishing down the food web the increasing effort needed to catch something of commercial value marine mammals, sharks, sea birds, and non commercially viable (vajabl) fish species in the web of marine

of disturbance. Some of these factors contribute to predictability of successional dynamics; others add more probabilistic elements. In general, communities in early succession will be dominated by fast- growing, well-dispersed species (opportunist, fugitive, or r-selected life-histories). As succession proceeds, these species will tend to be replaced by more competitive (k-selected) species. 39. Miks suktsessioon peatub? According to classical ecological theory, succession stops when the sere has arrived at an equilibrium or steady state with the physical and biotic environment. Barring major disturbances, it will persist indefinitely. This end point of succession is called climax. 40. Millised muutused toimuvad ökosüsteemide produktsioonis, hingamise intensiivsuses ja biomassi akumuleerumises suktsessiooni käigus? Suureneb biomass ja hingamine, väheneb produktiivsus. Suureneb liigiline mitmekesisus

milliste näitajate alusel ja positsiooni muudetakse ja tooteid täiustatakse. Selleks, et eesmärgid jääksid reaalsuse piiridesse ning oleksid juhtidele juhisteks, on kasulik silmas pidada nn SMART-reeglit, mille kohaselt peaksid eesmärgid olema: S (specific) konkreetsed M (measurable) mõõdetavad A (agreed) kokkuleppelised R (realistic) realistlikud T (timed) ajastatud STEEPLE ehk social, tehcnology, economic, ethical, political, legal ja ecological. Analüüsis käsitletakse vastavalt haridusnäitajaid. SWOT analüüs on samuti väga tuntud, lihtne ja laialt levinud analüüs, mille kaudu kaardistatakse organisatsiooni tugevused, nõrkused, võimalused ja ohud. On veel olemas Ansoff matrix ja BCG matrix. Majandusetunnid on minu jaoks huvitavad, saan palju uusi teadmisi.

palm oil production. Sustainable palm oil is an approach to oil palm agriculture that aims to produce palm oil without causing deforestation or harming people. RSPO is currently the largest sustainability-focused organisation within the palm oil sector, however its standards do not ban deforestation or destruction of peatlands for the development of oil palm plantations. Unlike many of the things we consume, which can have indirect ecological consequences, palm oil’s effects are direct. To stop the destruction we need to slow demand, in large part by making consumers aware of the clear link between the seemingly innocuous products we purchase and the environmental disaster they’re causing. As a consumer you have the right to say no and go the ohter way, more ethical, sustainable and healthful way.

Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summe...

Loodusturismi alused. Kordamisküsimused 2016. 1. Selgita loodusturismi mõistet laiemas ja kitsamas mõttes? Kitsam - Loodusturism on turismi vorm, mille peamiseks motivatsiooniks on looduse vaatlemine ja väärtustamine. Laiem - tootekeskne definitsioon: 'Loodusturism sisaldab kogu turismi, mis põhineb loodusel. 2. Selgita turismivorme: Maaturism: see on maapiirkondades aseteidev, kohalikul kultuuripärandil ja elulaadil baseeruv väikesemahuline, kohalike inimeste poolt juhitud turism. Loodusturism: on turismi vorm, mis keskendub looduselamuste pakkumisele ja kasutab selleks looduskeskkonda ärilistel eesmärkidel.

not even capable of making formal-looking curriculum vitae. Chapter two has ended what then? Our favourites the tests, of course! This time it'll be having listening part and grammar mostly, but a surprise attack is not out of the list, so everybody's got to be really careful and attentive in order to get a good mark (if that is possible at all). Chapter three concentrates more on a developing human himself; we're going to learn ourselves during the four units and make an ecological footprint can't wait until the last one since I've never made one myself before. Such topics as making a home, my room etc. are included as well. Another big test follows, including not only grammar and reading, but listening and speaking (!) as well. Hopefully it's going to happen after March, so we'd be having it after we've overlived the nice practice of the language in England, the best place to learn true English. Chapter four plays around the consumer society topic
