Over time, global climate change and more deforestation will likely lead to increased temperatures and changing rain patterns in the Amazon, which will undoubtedly affect the region's forests, water availability, biodiversity, agriculture, and human health. Human Activity in the Rainforest Biome has allowed for the discovery and implementation of many different medicines, nearly 120 prescription medications today are derived from plants in the tropical rainforest, nearly ⅔ of these drugs are known to have cancer fighting properties, not only are the drugs used to combat cancer, they are key in fighting malaria, heart disease .
