The article from newscientist.com had revealed the food made from methane by a biotechnology company in UK. The most refreshment we have eaten was made by plants as a result from their photosynthesis process just a few months or year before we ate it. A biotechnology company namely Calysta, is set to announce the factory that uses microbes to turn natural gas, methane, into a high-protein food for the animals that human eat. In the European Union, the methane-made food has already been approved for feeding to farmed fish and livestock such as pigs. Now, there is a question that is it goo turning fossil fuels into food for livestock. That depends on what people think is more important when it comes to protecting environment. The process would reduce the demand for land to grow food for livestock if it done on a large scale. However, it would also increase emission of carbon dioxide. Calysta is using a bacterium called Methylococcus capsulatus
. This bacteria are grown in vats, fed methane, and are then dried and turned into pellets. However, when methane is used for a food, then more CO2 are released into the atmosphere. This carbon emission could be reduced by using methane from a renewable source such as biogas, not from a fossil fuel.
