What if your favourite food became extinct?

It is possible. Flavours have been lost to the past as culinary physicist Lenore Newman explains. She points to the extinction of the passenger pigeon — one numbering in the billions throughout North America — as an example. In 1914, Martha, the last passenger pigeon, died at the Cincinnati zoo — and in place of the pigeon, came the industrialized farming of chicken. Newman says we're now transitioning lab-raised food — a technology capable of pushing a global history of scarcity into one of abundance, and that's all without any land usage. She calls it the "food singularity."
