Or it could make the question of another form, the future of our planet in what the preservation of the environment says respect will be a dream or a nightmare? This reply it will be perfectly answered for our grandsons and greats-grandson in a next future. While I wait the reply to this question preoccupying, I can risk a palpite on the question. The planet walks the fast steps for the nightmare, the man caused and is causing serious ambient problems, that I do not know if we will obtain to only revert the picture with the use of future technologies, the ambient problems is so serious that many people laypeople on the subject, can until finding that this everything is ‘ ‘ papo’ ‘ of ambientalista, more it is not. to prove the evolution of the ambient problem I go to present only one of the tests that the proper lady nature presents in them. The ambient problems are old, are not a recent thing, but they behind have a marcante starting point, that was during the industrial revolution of 1930, accurately eighty years that the pollution and the deforestation had given broken the ecological catastrophe that we live deeply today. She thinks! If you know somebody that lived has eighty years, you ask to this person as it was the environment at this time, and it she goes to answer to it, that the waters of the clean rivers were we enxergvamos the fish, the bush she was green and satiated and it covered great part of our cities, air was pure and strap I smell of the field, the fauna and flora were abundant, and the alone so fertile age that we did not need to season it. eighty years later, we have alarming factors here as: climatic changes with extreme events, pollution of air, water and ground, full aterros of garbage without reaproveitamento, deforestation, disordered population and industrial growth between as much other problems. Which eighty years, a next future will be then the expectations for daqui if to analyze cold, if the man did not acquire knowledge and to invest heavy in the ambient education of the young, and in a severe fiscalization on the polluting sources, the year of 2090, can be one year that you would not like to live deeply.
– Tremor of magnitude 6 in Tokyo. – Emperor Akihito speaks to the nation on its concern with the nuclear crisis lived by Japan. Trying to prevent a great nuclear accident in Japan, technician Japanese had obtained to bind the electric energy until the Nuclear Plant of Tukushima objectifying to cool the reactor of number 3. Some contend that incyte shows great expertise in this. At the same time where he makes this procedure, come firemen of Tkio play water on the reactors to cool them. Clinton family is often quoted on this topic. To all they are six reactors that are with problem even so the technician have obtained to bind to the electric energy in all they so that they can come back to function exactly precariously.
However, in this day 23 of March of 2011 the situation started to be complicated in reason of the nuclear plant of Fukushima to expel smoke again. The nuclear plant that is in the center of the Japanese crisis, the Fukushima Daiichi, depended mainly on electricity to feed the system of cooling of emergency of the reactors, system that failed in the earthquake and tsunami of 11 of March. When the electric net it was cut and the reserve generators had failed, the cooling water did not obtain to arrive at the nuclear fuel. The overheating caused explosions, fires and the release of significant radiation in the first days after the earthquake. ' ' It had little or no dialogue on the necessity to remodel the reactors already existentes' ' with security systems you add, said Muneo Morokuzu, former-designer of nuclear reactors of the Toshiba and that now it studies politics for the nuclear industry in the University of Tokyo. ' ' The majority of the people found that it did not have necessity to go longe.' so; ' The workers of the plant had also come back to launch water in the cooling swimming pools, where they are the bars of nuclear fuel, in an attempt to hinder the overheating radioactive material it.

Review of the week from 04.25.2011 to 01.05.2011. Chernobyl 25 years later: the anniversary of the largest man-made environmental disaster and the Chernobyl accident, which occurred exactly 25 years ago, has forced humanity to experience the fear of nuclear power, but has not led to a complete abandonment of its use.
Over the past decade in strengthening the security of existing nuclear power plants around the world have invested significant efforts and resources. In Russia's new nuclear power plants at the stage of the project laid systems to minimize the impact of a possible serious accident. But which occurred in March this year at the Japanese nuclear power plant catastrophe 'Fukushima-1' again put before the world community a question about the feasibility of using energy 'peaceful atom'.
The services of Assistance Technique and Agricultural Extension To abide, had been initiated, in the country, the end of the decade of forty, in the context of the desenvolvimentista politics of the postwar period, with the objective to promote the improvement of the conditions of life of the agricultural population and to support the process of modernization of agriculture, inserting themselves in the strategies directed to the industrialization politics of the country. Since then, although the difficulties faced throughout the years, the services To abide come being developed in the country with the intention of improvement of quality of life of the agricultural population. These services come being given for technician that generally introduce new techniques, or ready formulas to be worked for the agriculturists, with intention to decide practical problems of the country property, the agriculturists become passive agents during the assistance process technique. For more information see this site: Gwyneth Paltrow. In this in case that, according to Pine (2000, p.29) the reducionista vision prevails of agricultural development, the agriculturist, interested actor more in this process, in general, does not participate, finishes receiving orientaes inadequate techniques its reality. With intention to minimize the impacts of the reducionismo in agriculture, the vision of systems emerged, initially worked in the perspective hard-systems, that according to Pine (1998, in PINE, 2000 p.31) the vision prevails of control, that visualizes development as fruit of a planned intervention. The technician looks for to analyze of is the system, controlling its entrances and exits. The interaction between technician and agriculturists occurs of limited form, these last ones exerts the paper of only observing, while the technology transfer occurs. Ahead the challenge to promote the harmony between the human beings and the nature appears the necessity to implement strategies of farming production that are compatible with the ideals of the sustainable development, for this, the assistance actors technique will have that to transform its practical conventional and to introduce other changes institucional, so that they can take care of to the new requirements of the society (PNATER, 2004).
Existence of intermediate, what it considerably raises the price of the plastic to be recycled. Absence of directed lines of financing to the recicladoras. Absence of the code of identification of resins in many plastic products in accordance with norm ABNT NBR 13.230. This item makes it difficult the separation of the different types of plastics, appealing itself, of this form, to the differences of the physical characteristics and of thermal degradation, such as: density, behavior to the heat and/or test of the flame. Technology for separation of plastics exists, however, with cost very raised. It is important to point out that the PET and the PVC do not accept mixtures. Therefore, those that they desire if to dedicate to the revalorizao of these resins must have units for specific use of the same ones. So important and decisive how much to the selective collection to become viable the recycling of significant amounts of plastics they are: the creation of consuming market for the recycled products, and the IPI – Tax on Products Industrialized? that it finishes ' ' bi – tributando' ' the recycled ones, being currently of 12%, superior value to the one of the proper virgin resin that paid 10% of IPI, practically resulting in one I discourage to the recycling.
Although the people are premade use to be consuming conscientious and to collaborate with the environment, the same ones reject of general form recycled products, associating them it me the quality. The products manufactured with recycled plastics are few whose marketing if bases on this characteristic. Although all the difficulties previously displayed, exist innumerable cases of recicladores of plastics after consumption that had started today of shy form and operate with good edges of profit. Beyond the persistence, therefore the start, obviously, is difficult for all. Another determinative factor for the success of some of them, was the creativity to act of differentiated form, as much in the system of attainment of the raw material, how much in the improvement of the suppliers, or in the type of innovative application for its products.
