Urban agriculture: it’s a veggie-roots movement
As a child, I was lucky to learn food growing skills that have stayed with me ever since – including through a long career in finance and technology. I often wonder how many of today's adults could grow their own food if they had to. My vision is for organic gardening to be built into the national curricula from early childhood centres upwards.
