How secure is our food supply in Ireland? and who controls supply? Why are we exporting almost as much food as we are importing, while producing enough meat and dairy to feed a population 5 times the size of Ireland?.

Duncan Stewart explores the idea of a woodland corridor of native Irish trees planted along waterways, and looks at the efforts of those trying to save and restore Ireland's native woodlands - a task that would help to regenerate the biodiversity that has thrived for thousands of years.

Presenter Duncan Stewart explores the changing weather in Ireland, asking Met Eireann along with some of the world's leading climate experts for their views on the issue, which has seen the country importing food from the UK and facing flash floods.

Duncan Stewart investigates what the world may look like in 35 years' time, examining issues such as population growth and food production, and discussing what that could mean for Ireland's future. Featuring a visit to the world's `smartest' city to learn about the plans its residents have made to secure their future and contributions from several environmental experts.

Duncan Stewart explores how to create food and fuel locally to address a market imbalance where Irish communities import 98 per cent of their current supplies. The presenter visits the Aran Islands and North Tipperary to see for himself the efforts that have been made in creating sustainable changes.

Duncan Stuart investigates Irish agriculture, which is currently the country's biggest industry, and explores whether its current level of growth is sustainable.

Duncan Stewart explores how to save money while making environmentally friendly changes, and meets a Kilbarrack fireman who turned an ageing fire station into one of the greenest and most cost-efficient in the world.

Duncan Stewart investigates how the environment affects people's health, exploring the link between cleaning products and so-called superbugs, and revealing how chemicals in water sources are giving rise to intersex fish. The programme also looks at research showing that green spaces can provide health benefits, and questions what that means for future planning in towns and cities.

Duncan Stewart investigates the state of Ireland's water infrastructure, focusing on problems with the current system - including shortages and viruses - as well as what the real cost will be to the consumer.

Investigating the 'circular economy' system, which involves reusing and recycling minerals taken from the ground, which reduces both the environmental and monetary costs of the previously used wasteful system.
