The Declaration of the River on Environment and Development, standing out the beginning of the support. Agenda 21, a base so that each country could elaborate its plan of preservation of the environment.
Thousands of films, announcements and news articles had been made after this, valuing the nature mainly. The lesson that was incomplete: research of the Ministry of Environment, carried through in 2003, showed that 67% of the Brazilian population do not incluam the human being in its slight knowledge on ecology. little people knows today, until, that ' ' ecologia' ' it is the study of the place where if it lives. In the populated regions, where ' ' algum' ' it lives. But a more including knowledge was express of impactante form. The Copenhagen Consensus (2004), that it congregated nine economists world-wide of the great prestige, concluded that the main ambient problems of this planet were, for the order, the AIDS, me the nutrition, the trade barriers and the malaria.

The ONU now prepares the Rio+20, that will offer a possibility to the world in the fight against the poverty, according to undersecretary-generality of Economic and Social Subjects, Shah Zukang, who complements: the meeting will try to close an agreement of transistion for ' ' economy verde' ' , that it will have to help to reduce the number of poor persons in the world. Finally, we place the human being in the center of the attentions. It does not have nothing that degrades more the nature of what the misery and the illness.
