Compare the advantages and disadvantages of using bioethanol over fossil fuels.

Bioethanol is a renewable fuel produced from plants, which photosynthesise to grow, taking in carbon dioxide and producing oxygen. This means there is no net increase in carbon dioxide, which is a greenhouse gas. Furthermore, using bioethanol means fossil fuels are used up at a slower rate, helping conserve them. Finally, fossil fuels often contain sulfur impurities, whereas bioethanol does not, meaning that no sulfur dioxide will be produced during combustion. However, producing the fuel from plants also means that a significant amount of land is required to grow them due to the low yield of the production process. This land could be used for food, an important issue for a growing population. More land being used leads to the destruction of animals' habitats, leading to a decrease in biodiversity.
