WHAT I WANT IN THE PERFECT BEEF COW

摘要

Back in the early 1990s, headlines generated some interest in developing a "green cow." This green cow was supposed to produce (synthesize) its own food, just like our green forages. I believe it had something to do with photosynthesis, using sunlight as energy. Theoretically, that would have significantly contributed to making the perfect cow: low input with high output. So, did science fail because there is no such thing as a green cow?
