我確實有時會覺得某些皮製品是好看的，但當店家強調是真皮的時候，就變得不想買了。這篇介紹運用基因改造技術，不用再折磨動物就可以生產皮革的方式與好處...
"Factory-grown leather promises several advantages over skins taken from animals. One is that it can be made in convenient sheets with straight edges, rather than being constrained by the irregular shapes that animals come in. Another is that it is more consistent than the natural stuff. It is devoid of the scars, marks and other defects to which real skin is inevitably prone. Nor does it vary from animal to animal in the way that natural leather does. All these facts reduce waste and improve quality. They will also, presumably, please those who feel that animals should not have to die in order that people can have nice shoes and plush seat covers.
To produce its leather, Modern Meadow begins with a strain of yeast that has been genetically engineered to make a protein identical to bovine collagen. Collagen is the principal structural protein in animal bodies. In particular, it gives strength and elasticity to skin. It consists of long chains of amino-acids, the building blocks of all proteins, wound together in threesomes to form triple-helices that are then, in turn, wound together to make fibres."
