Big Washington Post story about a project to use duckweed as a main protein source for humans:
"Rubisco doesn’t just provide the protein we crave. It’s one of the world’s most versatile proteins, shape-shifting into forms resembling egg whites, meat, milk, gluten or even steak — all extracted from leaves. If we can harvest enough, it may elevate plants from a side dish to the main course — and as I found, it tasted delicious."
I knew that all that duckweed in my tanks would be valuable someday!
