At Lough Boora Bog in Co Offaly, Derek Mooney and Sinead Kennedy examine the current uses of Irish bogs as well as their future potential in helping fight climate change. Bogs have been a vital source of fuel and sustenance for Ireland's people for millennia, but there has been growing recognition in recent times that human exploitation of them has brought many species of plants and animals to the brink of extinction. The vital role that bogs play in preventing flooding will also be examined.
