So, what's the future regarding hunger? I'm an ardent believer in science. I hope that genetic engineering will make breakthrough after breakthrough, producing ever-better plants and animals to feed humans.
A technique called CRISPR (clustered regularly interspaced short palindromic repeats) snips a plant's own DNA as needed rather than inserting bits of foreign DNA as in past gene-splicing. The revised genome duplicates itself endlessly as new generations of crops ensue. National Geographic says it has potential to "help feed the world."
Here's hoping that gene science spawns a second Green Revolution and keeps humanity thriving.
