70 per cent of ducks bought in English butchers, game dealers and supermarkets have been shot with lead shot, despite that being banned 11 years ago. That's according to a new Defra funded study which has revealed that though the law was changed in 1999 to prevent other wetland birds swallowing the shot and getting lead poisoning, the majority of people are still using it to shoot ducks. But conservationists say lead poses a threat to both wildlife and human health. Also on Farming Today, The National park Authority insists there are no plans to privatise one of the country's biggest assets. The Government has just begun a public consultation, asking for views on improving the management of our national parks. Presented by Charlotte Smith and Produced by Anna Varle.
