A deadly bacterium that has ravished Italian Olive Trees could spread to other European countries.
Insects spread the disease Xylella which is one of the worlds deadliest pathogens. There is currently no cure for this. As well as Olive trees, Almond, Cherry and Plum trees are at risk.
Italy, Greece and Spain provide 95% of the worlds olive oil supplies. If the infection spreads to these countries, the economic impact could run into billions.
