One of our members found an article on feeding the growing population of the world in the future and the changing nature of food production that will be required. There are a number of ways that are given a quick run through – all of them have possibilities. As the article says, change takes time to bring through the system and many of the ideas require work, some investment, trial to make .
Of course changing to urban farming, organic farming or using permaculture will take time and will meet with resistance from those who are set in their ways but all the ways mentioned can be used. Go Local Food seems to be well on the road to the future reading through this article.
