Deforestation
In the AMAZONAS, the last remaining rainforest, some 40,000 criminal mafia organisations operate illegally to hack down the remaining large hardwood trees. Access being provided by the Trans-Amazonas-Highway supplemented by ever more airstrips none of which should ever have been built.
Everywhere so-called rainforests are just pitiful cash crop plantations where trees are grown to be cut down/exploited as soon as possible. Habitat that is now unsuitable for wildlife or birds.
Our nearest ancestors the Chimpanzee and Orang Utang are dying out for lack of undisturbed forests.
