The loss of tropical forests, to mostly agriculture farming, may become a source of greenhouse gases and limit the amount the forest absorbs carbon dioxide. The Paris Agreement of 2015 set a goal of limiting to the global temperature rise of only 2 degrees Celsius. If tropical forest are continued to be cut down, it could mean keeping this goal impossible. As of now, tropical forest take in as much carbon from the atmosphere through growth. The act of deforestation has made these forests a source of greenhouse gases rather than absorbing them. As animal grazing, farming, and mining become more popular in South America, Asia, and Africa the risk of these forests becoming a source of climate change are becoming more likely. This loss of the forest accounts for about one-fifth of recent human-made  greenhouse gas emissions. The high amount of carbon in the atmosphere do  allow for the trees to grow easier. Furthermore, if deforestation and degradation ceased and the forest were allowed to grow out, then they would once more help absorb a significant amount of greenhouse gases. Though it is difficult to predict an outcome, on one hand it is more difficult for trees to grow in higher temperatures and the occurrence of more droughts is  present, but the high levels of carbon assist the growth of trees.
