That's according to figures from the Environmental Protection Agency.
Only a third of Irish people believe that agriculture is the State's largest source of pollution that causes climate change.
That's according figures released in a report by the Environmental Protection Agency.
That figure is even less in the Midlands, with just 31% in Westmeath, 29% in Offaly and 28% of adults in Laois saying they know the farming sector is driving climate change.
The county with the highest figure is Cork at 38% and the lowest in the country is Donegal with just 25%.
