Minimising the adverse impacts of various activities on terrestrial biodiversity.
The transformation of terrestrial areas is perhaps the most visibly dramatic evidence of the loss of biodiversity. Terrestrial areas have been modified and transformed for purposes of cultivation or afforestation, for urban or industrial development, or to enable roads, railways and dams to be built. Areas which are not developed may be subject to overgrazing, to infestation by alien plants and animals, or to the overexploitation of certain species for subsistence or trade purposes.
