According to British and American media reports, a Japanese scientist invented edible "dung meat" from human excrement and used it to make a unique hamburger. However, this practice has caused great controversy. It is reported that Hiroyuki Ikeda, a Japanese scientist, recently discovered that there are abundant protein in human excrement through the experiment of reusing human excrement, and successfully developed an edible "dung meat". Ikeda Hiroyuki said that this kind of dung meat is made by separating protein from human excrement and mixing it with beans, beef and other substances, which tastes similar to beef. He also said that artificial meat has low fat content and less greenhouse gas emissions during production, which is very environmentally friendly.

The report also pointed out that "dung meat" contains 63% protein and 25% carbohydrate, which has high nutritional value, so its price is 20 times higher than that of real meat. But I hope that the cost of research and development will be reduced in the future, and mankind must overcome obstacles.
