I had an informative and enjoyable day at Brades Farm near Lancaster shooting pictures for an article about the ecological impact of dairy farming for the Financial Times.

Father and son farmers John and Ed Towers add Mootral - a garlic-based supplement - to their cows feed, reducing the methane emissions from their (the cows) profuse flatulence by 20% and lowering the environmental impact of the farm by 10%.

Thanks to Ed and John for the comprehensive tour, the coffees and the much needed lend of the wellies.
