Other pressures include alien species and exotic diseases, overexploitation, pollution, fire and climate change (Figure 1.13). Overall, about 70% of the total territory still has its original vegetation, in various degrees of conservation (MMA, 2010). The share of original vegetation varies widely across biomes, with the Amazon and Pantanal having more than 80% and the Atlantic Forest biome, where nearly three-quarters of Brazilians live, about 20% (Figure 1.13).
