In Northern Ireland peace and prosperity have long been prioritised over environmental protection. Tom Heap asks if a new generation can push nature and wildlife up the agenda. For decades a blind eye was often turned to suspect developments in natural areas and breaches of pollution regulations. A more recent upsurge in large-scale dairy, pig and poultry farming has added to the burden on Northern Ireland's once green and pleasant land. New laws to fight climate change and a new subsidy regime for agriculture give Northern Irish politicians and regulators the chance to put things right. With the help of BBC Northern Ireland Environment Correspondent, Louise Cullen, Tom Heap considers the issues in advance of the Stormont Assembly elections. Producer: Sarah Swadling
