We're on a "spring roll" here these last few weeks on Odd Green Fridays. Sunshine, green cleaning, solar chargers. And today, we bring you green greens — and veggies and flowers and all manner of plants.

Of all the urges of springtime, the one to grow things may be strongest in our household. We planted our seeds for squash and peppers weeks ago, rejoicing at every baby leaf that poked through. We've been hoarding toilet paper rolls to help start and then later transplant those seeds. And we're drooling at the prospect of their harvest.

Turns out we're saving the world. We're helping our species reach 350. That's the number of parts per million of carbon dioxide that scientists believe is the safe limit for us. We're now at 391 ppm — and rising quickly.

So we feel good that our greens are green — not only because all plants lower CO2, but also because they're local food. No gobbling up of fossil fuels to ship them around the world. All we need do is walk out the back door, and voilà, dinner.

According to 350.org, food production and delivery use 19 percent of our national energy — after cars, they use more than any other sector of our economy.

So give in to this growing urge if you have it. It's not too late to start your seeds this season. But it's closing in on too late for the planet.
