In its interior, the national currencies, would be substituted by a communitarian, emitted and controlled verge for a central banking supranational. With this, the exchange fluctuations would disappear that continue to individualizar the national economies of a common market. The borders politics would lose and any meaning all economic. (MAGNOLI, 1997, P. 46). Official site: David Green.

The idea of the Economic and monetary Union consists of eliminating the last impediment for the full functioning of the common market, hindering the governments to favor the national companies through the manipulation of the taxes of interests, that influence the exchange taxes directly. The ATTEMPTS OF ECONOMIC INTEGRATION IN LATIN AMERICA the first attempt of Latin American integration if must to the effort of Simn Bolivar. This descendant of Spaniard of Caracas desired a Latin America joined and exempts. However the diversity of situations and the game of interests had cut into pieces it in some countries. When Bolivar convoked the Congress of Panama, in 1826, already he was worried about the deep foreign influence, over all of England and the United States, in Latin America. Made it difficult or exactly hindered for the main American nations, Bolivar attended disappointed and impotent to empty its project of South American integration.

In the following decades to the Congress of Panama, unfruitful nationalistic movements had occurred. The borders had started to move themselves not in the direction of the integration, but yes of the interests of domination of the countries most powerful. Innumerable wars, sponsored for distant interests, had provoked bigger distanciamentos between the Latin American countries. Thus &#039 can be perceived that; ' since this time the unit of America configured a problem of geopolitical and economic order. The integration projects had become subjects of the external diplomacy of the States soberanos' '. (MAGNOLI and ARAJO, 1998, P. 17). With the sprouting of the European Common Market, in 1950, Latin America if to see in the necessity to search ways for the concretion of the economic integration in the region.

Future Science

The word Hydroponics is derived from the Greek words Hydro (water) and Ponos (work or work) and literally means "working water." Hydroponics is the science of crops without soil. Although hydroponics is, in practice, synonymous with "growing landless, this does not necessarily mean that plants growing in water or hanging in the air or water baths as is the case of aeroponics. There are several ways of hydroponics, some of which make use of solid substrates ARE NO LAND, such as coconut shell, rice husk, washed river sand, perlite, rock wool, etc. Plants in these substrates can have adequate support to grow, and also offer the ability to hold moisture and promote oxygenation of the roots of plants. The earth is a substrate for classical breeding.

Provides support, maintains moisture and has its own nutrients from the soil in the crop is made. On the ground, however, the oxygen flow is not good and can be transmitted bacterial and viral diseases also presented factors such as pollution of soil and groundwater. These problems do not occur with hydroponics, because the substrate that is used in the hydroponic SOLO offers the support and the ability to maintain moisture and oxygen to the roots of plants. Failed to provide nutrients and is easily controlled that is free from contamination and pests and diseases. Nutrients ARE IN THE WATER (HYDRO) used as the hydroponic nutrient solution. And that is where the true art of art, to have adequate nutrient solutions for each crop at different stages, from the nursery (seed), through germination, bud, growth, flowering, pollination, fruit production and harvesting. The advantages of hydroponics are many and include: * Does not depend strictly stations because it can be done in greenhouses. * Do not depend on soil quality in the geographical area in question.

* You can control the quality of nutrients in a more objective. * Allows the production of certified seed. * Allows the control of pests, parasites, bacteria, fungi and viruses. * Allows the best use of water, because it recycles. * Allows reduced use of toxic agents. * Do not use heavy machinery. * Can be highly automated. * You can protect yourself from the effects of climate. * You can calculate the economic return with an error margin lower than in traditional cultivation. * Fruits and vegetables tend to grow on a regular basis (all with the same average size) with no patches of land for better or worse quality because they do not depend on the land but the solutions and the substrate. * Allows the implementation of crops in urban and sub-urban (including patios, terraces, etc) in the form of gardens. * Does not require large tracts of land.
