Thanks for posting it, Taboule... what an interesting read!
I'm with you 100%, let the robots pull - or clip and mulch - why not?
Especially if solar powered.
Some of the agrochemical industry versions sound pretty awful. Imagine six different weed killers onboard, for a variety of combinations against resistant weeds... Unknown, combo residues in the field - but only in spots. So most of the food would test clean, but every now and then, somebody gets a nasty little chem residue coctail.
I would be more concerned about inconsistent residue levels of multiple chems, as a consumer, than I am now with the knowledge that yes some residues are present but they are monitored and expected to comply with a standard of safety. I have no reason to expect the industry would do adequate safety research on all the combinations of weed killing products. So there are a lot of questions raised in that article.
Can't wait to hear about the first organic robot!!
