Growing your own is about as green and good as it gets. It’s cheaper, fewer food miles, no pollutants, more nutritious, and rather satisfying to be able to serve it up knowing that you made it happen. All it takes is one pot on your windowsill, or you could get a few more seeds and harvest more, or you can even buy a ready-to-grow veg patch (and if you order in the next week you even get a free herb garden.*)
So go and grow your own this year, and be even more fucking awesomer as a result.
*PS We’re not getting a kick-back, we just think it’s cool.
