They also house 80 percent of our terrestrial biodiversity, eCollection 2016. van Kuijk M, Anten NP, Oomen RJ, Schieving F. Front Plant Sci. But Project Drawdown points out that they are often created with purely economic motives and little regard for the long-term well-being of the land, environment, or surrounding communities. It also calls them ecological deserts, as a stand of only pines, for example, does little to promote the multi-species plant and animal diversity found in a natural forest system.
