Week. This mystery box shows up at my doorstep. Its one of those subscription subscription boxes.
Except instead of dog toys or makeup. Its food from local farmers. I never know exactly what im gonna get got some salad greens asparagus and red corn but this wasnt always such an unusual sight if you look through old seed catalogues like these ones.
Youll see hundreds of varieties of corn.
With names like dibbles mammoth kendels early giant and my personal favorite potters excelsior . But none of these varieties exist. Anymore.
American farmers used to grow hundreds of varieties of sweet corn tomatoes and other edible plants today just a tiny fraction of those varieties are still around so what happened to all these plants for most of our time on this planet. Humans have been hunter gatherers we ate what was nearby this was still true when we invented farming 10000 years ago by cultivating wild plants like teosinte in central america and thorn apple in africa. The middle east and southeast asia over thousands of years farmers bred these wild ancestors into foods like corn and eggplant that we would recognize today as humans moved around the world.
So did the seeds and farmers continued to breed different varieties to adapt them to their new environments.
Which led to a ton of genetic diversity farmers could raise different genetic varieties of different crops if disease or pests killed one type there were others to fall back on but gradually industrialization and cheap fossil fuels made us less dependent on what grew well nearby food on the move from distant parts of the world comes. The great variety of foods americans demand. Most farmers switched from growing a variety of edible plants to a single crop.
That was easy to process and ship as this model spread beyond the united states older varieties of plants and animals disappeared from farms around the world by 1970 90 of the wheat varieties that had once been grown in china were gone as were 80 of the varieties of maize or corn. That were once grown in mexico by the summer of 1971. More than 85 of the corn planted in the us was genetically identical crop scientists had bred this new corn so that it grew without a tassel making it easier to harvest.
But because these plants were genetic copies of one another that also made them susceptible to the same deadly fungus southern leaf corn blight it took over the us corn crop costing farmers and taxpayers millions of dollars and the damage would have continued if it werent for a humble little plant called teosinte the wild grass native to oaxaca.
Mexico and the common ancestor of the 22000. Known varieties of corn teosinte includes a gene for resistance to the same fungus that was devastating the us corn crop scientists halted the damage by crossbreeding teosinte with american corn. But that didnt totally solve.
The problem of genetic diversity today more than 40 of the corn grown in the us is derived from just six inbred lines and seed companies driven by profit can repackage genetic copies of the same seeds for different prices farmers plant them thinking that theyre genetically diversifying their fields when really theyre not since the corn crisis in 1971 disease has ravaged genetically uniform crops of beans rice tomatoes and bananas and its about to get worse. The plants. We eat have spent thousands of years evolving to grow in specific conditions conditions we are changing rapidly by releasing more and more carbon dioxide into the atmosphere we depend on corn wheat and rice for more than 60 of our global calories and by 2050.
Well have 2 billion more people to feed.
But because of climate change. Well actually be producing less of all three of these crops. Were going to need plants that can grow in radically different conditions and the more genetic varieties.
We save the better protected. Well be there are seed banks. All over the world where scientists indigenous communities and farmers are all preserving older seed varieties.
But thousands have already been lost. Which is why its so critical to preserve the genetic diversity. We still have the weird stuff like red popcorn.
And the best way to save the seeds that might save us one day is to grow them and eat them .
