….According to the report, 75 percent of the food we consume comes from just 12 plant sources and five animal sources. And just three crops — wheat, corn and rice — make up nearly 60 percent of the plant-based calories in most diets.
The lack of variety in agriculture is both bad for nature and a threat to food security, the report says. It argues that it’s essential we change our eating habits to protect the planet and ensure we are able to feed our growing global population….
….Maria Haga, the head of Crop Trust, an organization focused on preserving crop diversity, says the new campaign is on target. “We probably have globally like 30,000 plants that we could eat,” she says. “We eat roughly 150 of those.” And to have just a handful of crops be so dominant is “really a challenge for the whole food system.”
Haga says dependence on just a few crops is also a threat to food security…. If we’re to feed everyone with a changing climate, says Haga, we’ll need diverse crops that can adapt to extreme weather conditions. The planet has lost thousands of varieties of foods in the last hundred years, says Haga. And once they’re gone, they’re gone forever….
….people are beginning to wake up to the problem and to the wide variety of alternative foods, many of which he grew up eating. One example is the ancient grain fonio, which resembles couscous. “It’s a grain that’s great for the planet,” says Thiam. “And it’s gluten free; it’s drought resistant; it grows in two months; it scores low on the glycemic index, so it’s great for your health too.”… Besides grains like fonio, they include various mushrooms, beans and pulses, nuts, tubers, algae and cactuses…
