@5342f2ee Nitrate pollution almost certainly, added to this warm weather. Until the government stand up to farmers, Ireland is going to have a big problem. Less animals and no more slurry derogations and that needs to start now. NI has no body of water in good standing because of this. It destroys the whole ecosystem-soul microbes, aquatic micro life, fish, plants, migratory species, and it will destroy our ability to feed ourselves if it’s not stopped.
