The disappearance of species and subspecies, many of them still noestudadas by science, deprives us of important potential sources of remdiose industrial chemical products. Epartes of our cultural patrimony destroys beings of great beauty forever; empobrece the biosfera. All we run risks, rich and poor, as much for quese benefits of activities that attack the nature how much the ones that did not sebeneficiam of it. The search of a more viable future has only felt if houveresforos more vigorous withholds the development of the ways of destruction. Environment and development do not constitute desafiosseparados; they are inevitably linked. The development if mantmse the base of environmental resources if does not spoil; the environment cannot serprotegido if the growth does not take in account the consequences of the destruioambiental.
