Biodiversity: Invasive Species Non-native alien species are increasingly having a detrimental affect on our native Irish plants, animals and fishlife. Eco Eye asks where these strange and unusual species came from and why they are costing us millions each year in extermination. Duncan also visits success stories such as in Lough Corrib where the battle is slowly being won against the invasive but deadly Lagorasiphon Major. Eco Tourism: Saltee Islands Tania visits Waterford's fishing village, Kilmore Quay and takes a boat journey to one of the world's major bird sanctuaries. Here we also meet Tony Murray from National Parks & Wildlife who is researching the local Grey Seal Colony. Cycling & Transport In Ireland our dependency on the car has caused a rapid decline in the numbers of people cycling to work and school. Eco Eye explores the reasons behind this and Duncan tackles the obstacles and difficulties faced by cyclists in their daily commute.
