(News24) - An Earth-friendly future for French wine could include disease-resistant grapes, solar-powered robots, and lighter packaging, as vintners innovate to slash their environmental footprint. "We can't keep functioning like this, polluting the Earth," Alexis Raoux, sustainability manager for the Bordeaux-based drinks group Castel, said. "What feeds us is the soil. If we continue like this, in a few decades the land will be polluted and our wine won't be any good."
