			- The main population of Cryptanthus ferrarius, along the road Mariana to Catas Altas, will be extinct in few years due to the large number of iron-mining activities carried out in the whole area. This mining activity, despite being economically important for the country in providing thousand of tons of iron required for the so-called world development, is responsible for an unprecedent large-scale devastation of the mounains of the Espinhaç range of Minas Gerais and its unique flora and fauna. —See J.
