For 25 years I sold healthcare and environmental solutions. Then I realised one of the biggest health problems I had ever seen was the lake I grew up beside.
Lough Neagh and many other waterways in Ireland and the UK are in nutrient overload. Too much phosphorus and nitrogen are entering the system, mostly from agricultural runoff, septic tanks and sewage storm overflows which flow untreated into our waterways.
The toxic blue-green algae you see on the surface isn't the problem — it's the symptom. The problem is upstream. And the only durable fix is to reduce the load before it ever reaches the shoreline.
