We Europeans like our things as poison free as possible.
While we do use pesticides and herbicides, even I do on my small garden, they are of a more eco-friendly, less efficient variety. The one I use is non-toxic to warmblooded animals and disolves in sunlight. I spray it in the evening and when the bees start doing their rounds it's already inactive.
There's something very retarded about killing the one animal that makes your produce possible
That's why the strict legislature, billions of euros were lost because bees were dying.
And the legislation was forced by the general population because of this reasons, the governments would preffer not to be forced into something new they'd have to enforce and actually have people working a their job.
