Japanese scientist use proteins found in sewage mud to create edible proteins as meat substitutes.
Although I agree with the ingenuity of the research, and the idea of having less animals for meat, and the concept of reusing waste, I would think twice about eating this meat. Proteins have be reused from many sources to create “meat”, hence textured vegetable protein. However, I don’t believe there would be any pure sources of nutrients in these new meats. Most nutrients will have to be inserted and most likely they will be synthesized nutrients from laboratories.
Scientists in the United States are also researching GMO lab grown meats in the name of “Going Green”. Laboratory grown meats will reduce carbon emissions, reduce the amount of land needed for livestock, and keep the animal rights activists happy, because there is no consciousness from the slab of porterhouse they are growing.
The larger issue that prompts science to conduct this research is the high demand for meat.The cost of oil has gone up, along with all things related. The cost of cramming animals into 6 square feet their entire lives has become too costly for industry, and drives the price up for wallet wary consumers.
These scientific advances do not solve the problem, they are merely patching up a leak, rather than looking for the source of the problem.
