The future - Let's all feed ourselves!!

This is fabulous in every way. Hugh F-W has launched an initiative called Landshare with Channel 4 (http://landshare.channel4.com) - where people who want to grow things can pair up with people who have land that they don't use. It's all about getting us back to growing our own fruit and veg. After the war there were about 1.5 million allotments in the country and we got half of our fruit and veg from them. Now we all rely on the horridness that is Tesco etc, to feed us. Why?
On River Cottage last night, there was a woman who lives in a 2nd floor flat, so she "borrows" someone else's garden to grow her vegetables. In exchange, she gives the garden owner a quarter of what she grows. She hasn't had to buy vegetables since and the whole thing cost her £30.
Such a fantastic idea, we all live under the misconception that we have no space to do things like this. But there's so much land that isn't being used - all we need is access to it.
This has got to be the future. We'd be better off (because we won't being ripped off by supermarkets for vegetables that have been flown in from Guatamala), happier (in our glorious self sufficiency), more relaxed (what better way to de-stress after work/at weekend, than with a couple of hours tending the broccoli).
Here's to growing marrows.
