there is some truth to this. same news was posted here on HN last year. but in reality, there is more to it. yes, there is a pathogen. but EU olive industry is moving to turkey and morocco. why? simple. cheap labour. olive trees can live for a very very long time, but there are two kinds of olives harvested. for oil and then for table olives. the former has been mechanised and the latter is not. so it's expensive. it…
Sure there are a lot of mass production olive oil across southern europe consisting of 'young' olive trees.
