Part C 29. Carbon dioxide is known to be a greenhouse gas that contributes to global warming. Due largely to human activity, such as the burning of fossil fuels, the amount of carbon dioxide in the atmo- sphere continues to increase significantly. Dis- cuss how planting more trees could help reduce the amount of carbon dioxide in the atmosphere. How might this slow down the rate of global warming? the world are being

As we know plants are a sink of carbon, through the process of photosynthesis carbon dioxide is fixated, now this has been widely discussed if this will actually would help to decrease carbon dioxide in the atmosphere as trees also breed. In the case of young plants, the rate of photosynthesis surpasses the respiration rate however once the growth has slowed both rates are similar, now there are other photosynthetic organisms that could make a bigger difference and those are cyanobacteria and algae. Finally, we can say that more plants can help however the majority of their benefits come from other aspects such as habitat or decreasing urban heat, as carbon sinks there are more efficient organisms, likewise, carbon dioxide is not the only greenhouse gas, there are other gases with greater impact like methane.
