Winter A Franciscan Blessing 2004/5 May God bless you with discomfort at easy answers, half truths, and superficial relationships, so that you may live deep within your heart. May God bless you with anger at injustice, oppression, and exploitation of people, so that you may work for justice, freedom, and peace. May God bless you with tears to shed for those who suffer from pain, rejection, starvation, and war, so that you may reach out your hand to comfort them and to turn their pain into joy. And may God bless you with enough foolishness to believe that you can make a difference in this world, so that you can do what others claim cannot be done. Amen A Letter from South Africa “It appeals to our ego to consider what ‘we’ have and what ‘they’ need. I went to South Africa once, to a small village about 800km from Cape Town. The people were extremely poor, conditions were basic; alcoholism was rife. My first impression was typical of a Westerner: I thought ‘These poor people...’ and I thought about what ‘we’, in the prosperous North, could offer people in poor developing countries. But, by the time I left, having been invited into homes, eaten and laughed with both kids and adults, talked to folk wherever I roamed, I came away thinking more about what they had to offer to us. The visit made me realize that in our greedy pursuit of wealth we have lost a great deal of what money cannot buy. Our value system has gotten out of kilter with what is important in life. The people I met had an abundance of natural generosity, exuberance, lust for life, sense of community and family. I am now more worried for us and the road that we are walking, blinded by unconscious greed because we always look after number one. We all, rich and poor alike, have something very valuable to gain if we share the world resources more fairly, and if we look again at what is really valuable in life.” (Fran Healy, singer/songwriter with the band Travis) This passage comes from “The Rough Guide to a Better World”, a book published by Rough Guides, for the Department for International Development. It contains lots of information relating to both the developing world and how we can help, through charity and lifestyle.

The leaf mulch and lack of cultivation mean the crop is good for wildlife. Grants are available if planting within 10miles of a small biomass user, 25miles of a large one. Alternative uses (not grant attracting) include equine bedding and composite materials. BiEcc is a local company set up by farmers and Bical as a contractor to plant and manage Miscanthus crops – contact BiEcc at Site Office, Raleigh Hall Industrial Estate, Eccleshall, Stafford, ST21 6JL. They are particularly seeking farmers panels. Over 3200 m2 of Sharp panels, of nominal within a 25 mile radius of Eccleshall to supply a 391kW rating, will generate 180,000 kWh of biomass power plant there – this includes the electricity annually.
