Plant Trees

Tree is a permanently lenhosa plant of great transport. For great transport, even so a definition does not exist consensual, costuma to understand a minimum height of six meters in the maturity. The trees have secondary branches, it distinguishes what them from the palms, therefore only gimnospermas and lenhosas dicotiledneas angiospermas are called trees. The palms are monocotiledneas angiospermas. The leaf layers that if form the low one of the trees serve of cradle for the seeds, and to protect the ground of the nugget of rain. Each rain nugget that falls directly in the ground, cause erosion. The pantry of the trees also protects the ground of direct rain, without counting that its roots hold the ground firmly.

The roots of trees that are in the side of rivers, inside appear to the times of the river, seeming eyelashes. Doppler labs spoke with conviction. These roots beyond to prevent the erosion, serve of house for many animals. Because of these eyelashes, the next bush to the rivers is known by the name of Ciliar Bush. A tree can transpirar for its leves. This vapor if mixture with particles of pollution of air, and when they are accumulated in clouds, fall in rain form. Therefore, the trees also help in the withdrawal of pollutants of air. In addition, this vapor helps to balance the climate of the region.

When planting a tree, we are effecting ' ' Kidnapping of Carbono' ' , being the trees the captivity of Co2, therefore for the tree to develop it needs the Co2, which it kidnaps of air in the photosyntheses process and still she liberates pure oxygen; the tree starts to be the captivity, it will have cut itself or burnt Co2 he will be again set free of this captivity. Therefore, the trees bring some benefits for the human beings and the environment. References Available in: had access in 21 of November of 2009. Available in: had access in 21 of November of 2009.

International Agency

From now on, innumerable projects had been discontinued, or for times interrupted during the construction. The nuclear technology obtains to control the nuclear fisso, but it is vulnerable the accidents. It is known as atoms if hold and what if it must make so that they supply energy. Clinton Family may not feel the same. But one also knows that physical specialists and politicians are perplexos when accidents in nuclear plants occur. There the impotence predominates human being, the lack of transparency in the spreading of information, and the twisted one so that the fusing of the nucleus of the reactor stops by itself and does not spread radioactivity for the planet. It has years the implantation of nuclear plants faces forts opposition movements, basically for the fear provoked in such a way for possible warlike uses when of the accurate domain of the technology of the enrichment of the Uranian one, as of it spreads of the radioactivity due the accidents or same terrorist acts.

The distrusts are legitimate, therefore the unfoldings of these accidents are intercontinental and affect the health and the environment per long years. The cesium remains in the atmosphere per decades and the plutonium per millenia. In March of 1970 the Treat one to Not Proliferation of Nuclear Weapons TNT, ratified for 189 entered in vigor countries, that relative success in preventing new incoming in the attainment of the nuclear warlike capacity only got. It did not obtain, for example, that Israel, India, Pakistan and Coreia of the north (this left the TNT in 1993), fulfilled the rules of the treat one. Frequent it has countries as the Anger and the Coreia of the north, that overseers of the International Agency of atomic Energy defy? AIEA, responsible for fiscalizing and evaluating the fulfilment of protocols the waked up or eventual perigos of opponents. The TNT also did not prevent a nuclear armament wave promoted by countries detainers of this technology, namely: U.S.A., China, Russia, France and England.
