This movement lasted one month more than and involved laborers of all the branches of the industry, as metallurgist, masons, shoemakers, marble workers and seedbeds, graphs, teceles, hat makers, dressmakers, workers in wood. It is important to detach that the wages were not paid during the strikes, being thus, many times the laborers finished coming back to the work without nothing to obtain. The conquests gotten with the strikes never were definitive. Therefore, from time to time, the laborers entered in strike; in 1906, the railroad workers of So Paulo had stopped for better conditions of work and wages; in 1912-1913, laboring of some categories they had 1912-1913 made strikes against the high prices of the life and for better wages. First the great movement striker of syndical history in Brazil that paralyzed the city of So Paulo in 1917, was initiated with strikes located in txteis plants, in the quarters of the Moca and the Ipiranga. The leaders strikers demanded better wages and better conditions of work, beyond the requirement of suppression of the contribution ' ' pr-ptria' ' (campaign of financial support to Italy, developed for the immigrant bourgeoisie of So Paulo, arriving until making discountings of the wages of the workers, as it was the case of the Cotonifcio Crespi).

In way that the deduction on the studies of Ratter agrees that the roots of the majority of the ambient problems are of nature social politics or and that many problems of this order can be decided, having will politics and certain conditions of cohesion and social solidarity in the society. This application of ' ' gua' ' , they must just fix a price for the water, nominated thanks to a tarifao of the water based on a economic evaluation of the uses and the value of this and to the introduction of programs of obligator measurement of the water consumption. On the other hand, in order to limit the negative effect of the economic development of certain hidrogrficas basins and to promote the use rational of the water, the distribution of the water and the respective financings would have to be more efficient. Thus, emphasis will have to be given to the destined measures to improve the order of the territory, and in special to the integration of the question of the water availability in the exploration of agricultural lands, to the strict application of the directive one on the strategical ambient evaluation (), to the census of the hidrogrficas basins that suffer frequent or permanently of water lack and the adoption of disposals of management adequate to these basins. According to Ayers and Westcot argue the following one: The reduction of the availability of hdricos resources of good quality and the increase of the production of domestic and industrial oustings, have stimulated the water use of inferior quality in the irrigation, whose evaluation if becomes necessary (Ayers & Westcot, 1991, P.
