From the inherent value of biodiversity to the role they play in regulating global climate patterns, rainforests
have tremendous local and global impacts. For example, the Amazon rainforest has been called 'the lungs of the world'...why? Discuss some of the local and global impacts rainforest have, current issues such as deforestation, climate change and/or medicinal discoveries. This would be a great thread to include maps, photographs, graphs and article references in your posts. Please provide details when discussing examples--rainforests are found on multiple continents, so reference which specific forest(s) you are discussing.
