Dog poo in little black plastic bags left by walkers is a blight on the countryside, but farmers are alarmed at suggestions the offending matter should be left to rot naturally. They say the faeces can carry diseases that cause cows to abort their calves and want dog walkers to bag the poo and bin it, preferably a long way away from their fields. Scientists aim to find natural ways of dealing with pests and diseases that have become resistant to traditional chemicals. A project aimed at improving the country's hedgerows is about to be launched. And a multi-million pound project is restoring peat bogs in Scotland.
