According to the report ‘Our common future’ by Ms. Harlem Brundtland, Sustainable Development is defined as development that satisfies the needs of the present without compromising the ability of future generations to satisfy theirs. This report, published in 1987 by the United Nations World Commission on Environment and Development, insists on the need to protect the diversity of genes, species, and all terrestrial and aquatic ecosystems in nature. This is possible in particular via measures to protect the quality of the environment, and by the restoration, development, and maintenance of habitats that are essential to species. This implies the sustainable management of the use of the animal and plant populations being exploited. In other words, it is the rational management of human, natural, and economic resources that aims to satisfy the essential needs of humanity in the very long term.
