A remember a thread a few days ago about making Ecocide an international clime. Well research suggests that nano particles produced by diesel engines could be messing up bees and hence the recent alarming drop in their numbers.
So all you diesel drivers could find yourself getting a one way ticket to the Hague!
Not being an expert on bees I googled "nano particles diesel bees" and the following is fairly representative of the results :

Apart from the widespread use of pesticides in the countryside the growing of vast swathes of a single crop which has a limited flowering period really isn't going to keep the poor bees sustained. I suppose that's why in the US they transport hives thousands of miles in articulated lorries so they have enough food ie are always available to pollinate crops when they are needed before being moved onto the next one. No wonder they are feeling slightly stressed
