Down To Earth is Newstalk’s dedicated programme about our natural environment and how we address the limits of our planet's resources.

From climate change to species extinction, we cover the toughest challenges with leading experts and celebrated thinkers. You'll hear diverse views, as we try to find common ground in how to fix our most pressing global crises.

This week, we look at water quality, both at home and abroad.

Sinead O’Brien of the Sustainable Water Action Network gives the low down on Ireland’s water quality.

Trish Murphy talks about how Inishowen River Trust is slowing the flow to manage flooding in Donegal.

Barry Deane explains the risk of pollution to our drinking water supplies.

From the USA, Charity Water’s, Brian Hoyer, takes us around the world in the fight for clean water.

And the Winky Weatherman, Gerald Flemming, is the guest this week for 'My Green Life' - where he explains how his career as a meteorologist brought him to the front lines of the climate crisis.
