In the last few decades, new farming technologies like surveillance drones, autonomous tractors and high-tech greenhouses have greatly reduced the costs of growing food and helped increase the food supply. Looking ahead, new advancements in weed control techniques could be the next big agricultural tech breakthrough to help transform farming and improve the environment. 

The advent of automated, laser-guided methods of weed control for agriculture could mean that farmers will no longer have to use potentially dangerous herbicides or less effective natural weed control options. In light of public concern with the use of herbicides, some regions of the U.S. have
