Yet scrutiny over these debates reveals a worrying trend; more people are supporting a pro-GMO stance on the grounds of solving sustainability issues, before considering whether more ethical and sustainable alternatives exist. Recently in the world of GM, scientists have managed to create “surrogate sires” (Ciccarrelli et al., 2020, p.1). These are sterilised male animals who act as vessels for the production of sperm donated to them from another male carrying a desired trait.  The technique involves using CRISPR-Cas9 technology - a game-changing gene editing tool that can knock out the male fertility gene in sires and make them sterile. Sperm-producing stem cells can then be transplanted into surrogate sires, enabling them to carry traits from the donor. Male mice, pigs, goats and cattle have all been subject to the technology, but so far only surrogate mice h...
