And also, more importantly, who knows real cases of authorities paying attention to and obeying the results and recommendations of the EIA, and the Environmental Declaration? Effective management and conservation of biodiversity in areas affected by development could be improved if EIA processes are seriously treated by authorities.
EIA is not only politics, but also (and mainly) science; however, politicians are not always prone to pay too much attention to such issues. For example, most politicians must consider that impacts are cumulative, interactive and sinergic, and that the ecological landscapes are limited in their carrying capacity, and that, hence, EIA should include an evaluation of any previous source of impact or disturbance which accumulates and interact with the new ones to reduce and deteriorate biodiversity.
