For example my initial thoughts regarding the use of biofuels were quite positive, as I believed that creating fuels from plants would decrease our carbon emissions. Upon further research, I discovered that this might not necessarily be the case as a large amount of energy is required in the production of biofuels, which may not outweigh the benefits. Furthermore, I hadn’t heard of the “food versus fuel” debate before, which I now know is in regards to crops for fuel production limiting the arable lad available for food production and therefore may contribute to a world food shortage.
