Several medicines that treat human diseases have been sourced from plants in tropical rainforests. For example, quinine, which i

As only approximately 10% of the plants in rainforests have been investigated for medicinal compounds, researchers predict that there may be many more plants with medicinal properties yet to be discovered in rainforests. Deforestation of rainforests would most likely affect such plants by causing....
