Farmers need to deal with weeds in a more environmentally friendly way.  Global warming makes weeds grow faster which means that farmers must use more chemicals.

The surprising fact is that 95% of these chemicals go into the soil or they end up on plants. Spraying fields is expensive and very inefficient. Startups like Precision AI are introducing a fresh approach with AI-powered drones which reduce chemical use by up to 90%. Traditional farming uses expensive machines like ground sprayers, which cost a lot and farmers use them only a few weeks a year.  Precision AI uses AI drones which scan fields, check plant types, and spray only the weeds. This saves about 95% of chemicals compared to old methods.

Difficult words: weed (a wild plant which grows where people do not want it), approach (the way of dealing with a problem or situation), inefficient (a person, system, or machine that does not work in the best way and wastes money, time or energy).
