Practical one that it designates the arrival definitively of squares Christmas is the assembly of the celebrity and adored Christmas tree. This is a scene that, for the smashing majority of the families, if uncurls in an environment of full tranquilidade, being irrelevant any types of external quarrels to the mere act to celebrate the Christmas. However, a controversy that if repeats year year after and that it involves some organisms of the scientific community, as well as some associations of carcter exists not-governmental: the debate around the ambient impact that the Christmas tree involves. In cerne of the quarrel it is already the old question to decide that sort of pine of Christmas, if artificial or if natural, is the solution most ecological. It has some years behind, the lesson that if taught in the schools was clear and direct: the artificial option is most sustainable.
The arguments that presented in them, by the way, were fully convincing. To know more about this subject visit Gordon Allport. The risk of desflorestao caused for a massivo cut of trees it justified the artificial option fully. However, passing of the time brought new ideas and realities, and currently the use of the artificial pine already is not so consensual. However, having in consideration that most of us since was always taught to opt to the artificial one, it will be interesting to observe what it will have moved however. The main problem of the false pines is in the fact of its production to be made to the policloroeteno base, a substance derived from fsseis fuels not passvel of reclagem. In according to place, it stops beyond already the cited composition, has several other pollutants freed during the production of these trees that are cancergenas, being one strong public threat to the health.
It is the case of the 1,2-dicloroetano and the dioxinas. It also has other composites that are applied to become the plastic most malleable and that they cause some problems to the level of the devices reproductive and renal. But although this terrifying scene, many also insist that the culture massivo of natural trees has equally dangerous consequncias for the health and environment. The erosion of green spaces is not only a risk more than known, as well as the constant pesticide use and used chemical seasonings in the commercial culture of pines, what it puts all at risk a public water net. Thus being, it has that to conclude: which is then the best solution for the problem? Of all the involved problems, of the natural trees seem to be most easy to skirt. By the way, already exists makes who it: to practise a biological agriculture (not-pollutant) in the culture of the pines and to vender them with the roots! In time to abate or to order to abate a tree, if you to buy with the enclosed root and to preserve it, most of the problem could be decided. When making it (and articulating with more ecological methods of agriculture), he will be helping to have a more ecological Christmas, skirting the counterparts and betting in the benefits. If he has not limited to be seated waiting for the Christmas presents: it offers to you yourselves a gift to the planet, contribundo for a better world.
To know if this relation is beneficial or is still more harmful to pluralism. Until point can exist or it transacional relation between culture and capitalism and thus the Amaznia not to be able to be seen of a form in which, perhaps, never it are seen, a possible more distant vision of the Golden El, vision that lasts on it has some centuries since the exit for first navigator route to the unknown Sea of the Ocidente. Read more here: Luxify. To raise questionings on this aspect beyond reviver the process of Brazilian settling, with the strong European oppression in the attempt of aculturao of the indians to become them allies of the metropolis with the calls missions, is also to perceive now that great part of it I still begin colonizador is remained, not more for Europeans, but yes for also living Brazilians and of the proper Amaznia. THE AMAZNIA AND THE CAPITALISM: A COMPLEX APARTMENT the Amaznia if presents today as a great source of natural and cultural wealth of the world, aspects that had always met in same, but only one extremely was valued during the centuries, of marketing economic character, that always prioritized the exploration of the Amaznia the lucrative ends, deforesting, extracting and burning, disrespecting of cruel and humilhante form there existing the cultural manifestations that depend directly on the natural way where they live. If you are not convinced, visit Sanofi. For better understanding of what it is if to say becomes necessary an embarkment in caravelas of the Europeans, travelling in the history of the arrival of the man ' ' white civilizado' ' in the Amaznia, that in search of new sources of wealth, still existing in the Europe, but little for the imperialistas ideals, would not allow that nothing a multitude of equalized natives opposed itself much less in its way ' ' animals selvagens' ' The known historical period as Average Age, period that precedes the routes of ' ' discovery of the Amrica' ' , with its feudal regimen it starts to present its first steps of decay parallel the limitations of considered products indispensable dominant social classroom, this fact made with that the commercial relations if expanded beyond the feudals, until then, self-sufficient. .

According to PAIVA recommendations (2001), in the composition of the vegetation of a square if do not have to introduce toxic species or that they present physical danger to the users and nor so little fruitful species, therefore they can cause some upheavals to its users (figure 2). As, it was observed that, species: Euphorbia you ingest laciniosa Bromlia, Mangifera indicates had been found with sufficient frequency. Inadequate species for square: Laciniosa Bromlia SOURCE: IT HISSES, M.L. 2006. In accordance with SAINTS (2001), species that present system to radicular superficial in reduced area and depending on quality of the used material, the pressure exerted for the roots will be able to provoke trincas and to compromise the space where if they find. Species was evidenced that as the Mangifera indicates rigid Parapiptadenia and other identified individuals do not compromise that physical space when observing (figure 3), see that the roots are provoking the particle disaggregation of the ground, this process if it intensifies during the rainy period. Figures 3? Species not identified that presents voluminous roots: SOURCE: IT HISSES, M.L. 2006.
The species diversity does not determine the identity of a space COAST et. al (1996). The 15 found species, in the square probably are proceeding from random plantios carried through by employees of the city hall who were unaware of the techniques of arborization of an area. Species with 3 and 2 individuals had been found representing (4.90%) and 5 species with only 1 individual representing 4.09% of the total of plants. Another indication that discloses the lack of knowledge and planning are that 17.21% of the trees and shrubs divide the space in one same seedbed (figure 4), other well next ones to the others without mensurao of espaamento. Mangifera indicates Psidum guayava, rigid Parapiptadenia, Hibiscus schizopetatus, Euphorbia you ingest and other strangers had been distributed of random form in the seedbeds.
At maintaining the pace of modern mass extinction may occur in three centuries. Scientists argue that the cause of the sixth mass extinction would be human activity. Its harmful effect is damage to habitats, relocation of animals, spreading disease, killing fish and climate change. In order to prevent the massive extinction of species, experts urge humanity to action today: it is necessary to allocate money for preservation of endangered species, to make laws for the protection of flora and fauna. It should be noted that not only mammals are threatened with extinction. Extinction threatens and other species.
For example, in 2010 published a number of studies on the sharp decline in populations of reptiles on Earth. Thus, the study populations of snakes in Europe, Africa and Australia showed that over the past two decades number of reptiles has decreased significantly, and the reasons for this are unclear. The authors of another work believe that by 2050 nearly warming will inevitably lead to the extinction of 6% of the lizards, but if you do not take the necessary measures, by 2080 could disappear out of every five of their appearance. A rapid pace today is the extinction of bees. Scientists claim that the extinction of bees, which recently is due to unknown reasons, can aggravate food crisis has already begun on the planet. Plastic bags and the environment is very unusual for the results reached by researchers from the UK. They found that plastic bags are much greener paper packets and canvas bags.
How to lose? First of all, increased secretion of gastric juice and its acidity, the deterioration process of absorption of water in gastrointestinal tract, resulting in deformed intestinal mucosa. And the longer this drink "dead" water, the less remains in the body of calcium, phosphorus, and alkaline phosphatase. Feel like mineral starvation is simple – the body as a powerful computer, just takes distress as dizziness, fainting, and muscle spasms. And this is just the beginning, as long calcium loss threatens the destruction of enamel, frequent bone fractures and the development of various serious diseases. So far, based on experience and research specialists, we can safely assume that many of the diseases are in daily use contaminated water. Microfiltration, ultrafiltration, nanofiltration membranes can be used for water purification, but in the complex, because they do not have the ability to hold bacteria and viruses. They cost between 300 to 1,000 rubles. Reverse-osmosis systems are quite expensive from 20,000 to 60,000 rubles.
Household filters almost all water filters are based on coal cleaning. Absorbent carbon has a large surface area and is able to absorb large molecules of organic compounds, bacteria, and any mechanical particle, but this method of treatment does not protect against a variety of harmful substances. Moreover, For example, the filter-pitcher cartridges should be changed 1-2 times a month, otherwise there is accumulating rapidly multiply and harmful bacteria. For the sake of saving many neglected frequent replacement of cartridges. As a result, bacteria in the water at the outlet of the filter is greater than the input.
Weather – fickle and unpredictable thing. For us, but not for weather forecasters. On what to expect from the weather during the second half of May, they have learned our journalists. In early May, in Europe suddenly snowed. Ukrainians should not be afraid sudden changes in weather – forecasters say.
