Topic sentence: "Pollution is a problem that people are becoming increasingly aware of"

In our day by day it is possible to recognize the pollution that is around us. Moreover, in a micro-dimention, for instance: trash at streets, highly construction of buildings, smog in the cities etc (a more human context). And, on the other hand on a more macro-dimention, as follows: unfrozing of the ices, acid rain, erotion of the ground etc (a more nature related context). Consequently the human activity in pos of taking the task of doing something about the problem, has increased. A lot of enviromental ONG's, international organizations and reunions specifically motivated by the complain of solving the topic of pollution are emerging strongly.

Particullary, taking the micro-dimention is possibe to show how people it is generating a sort of enviromental concience that 20 years ago did not exist or exist in a lower grade. In the case of Chile, Santiago different organizations are trying to promote this emerging concience, by doing certains activities in their local places. Universities, working places, poblations -for instance- have more reciclating iniciatives, propoganda for taking charge on the own trash and even for cleaning determinated places.

In the case of the Social Science Faculty from University of Chile there exists a enviromental comission who takes charge of this kind of topics. Ocacionally, in determined weeks of the years there is a reutilization period of the academic material, that is; printed books, fotocopies, notes etc. Also, in periods of electionary campaigns (to inside the university) the phamplets and similar propaganda are recicled and reutilized.

On the other case, under a more macro-dimention it is possible to see all the movement around problems that concerns directly to nature. The Kyoto Protocole or ONG's like Greenpeace.
