Getting back to my previous post regarding growing stuff, thanks to Jack for this link:
Don't Give Up
To quote briefly:
"Yet the sun still shines down on your garden, and photosynthesis still works so abundantly that in a thoughtfully organised vegetable patch (one planted from seed, nourished by compost from the kitchen and involving not too many drives to the garden centre), you can grow the proverbial free lunch - CO2-free and money-free. This is the most-local food you can possibly eat (not to mention the freshest, tastiest and most nutritious), with a carbon footprint so faint that even the New Zealand lamb council dares not challenge it. And while we're counting carbon, consider too your compost pile, which shrinks the heap of garbage your household needs trucked away even as it feeds your vegetables and sequesters carbon in your soil. What else? Well, you will probably notice that you're getting a pretty good workout there in your garden, burning calories without having to get into the car to drive to the gym. (It is one of the absurdities of the modern division of labour that, having replaced physical labour with fossil fuel, we now have to burn even more fossil fuel to keep our unemployed bodies in shape.) Also, by engaging both body and mind, time spent in the garden is time (and energy) subtracted from electronic forms of entertainment."
Whether you're converted and like to be preached to, or are in need of a bit of convincing that there's something we can do about our vampiric energy needs and its environmental impact, this is a well-written, well-thought out article, imho.
