BRASILIA, Dec 7 (Reuters) - Brazil runs the risk of losing control over its vast Amazon rainforest region to organized crime and traffickers who use the lawless region to smuggle drugs, a Supreme Court judge warned on Wednesday.Justice Luis Roberto Barroso proposed that environmental experts, investors and local authorities come together to brainstorm on how to foster sustainable development that would preserve the Amazon rainforest, the world's largest, and help the livelihood of the 25 million people who live there.The Amazon absorbs vast amounts of greenhouse gas responsible for global warming and its preservation is seen as essential to the fight against climate change.Under Brazil's current President Jair Bolsonaro, illegal activities have surged in the Amazon, encouraged by the easing of environmental protections and reduced funding for enforcement agencies.Barroso, who attended COP27 United Nations climate talks in Egypt in November, proposed that Brazil gather "the best minds in the world" to discuss how to develop a "bioeconomy" for the Amazon to stop the degradation of the region."
