12:38 Kerry McCarthy (Labour)
The Bill is not just about tackling food poverty. By creating unnecessary demand, waste drives up food prices and the surplus puts pressure on scarce land and resources, contributes to deforestation and needlessly adds to global greenhouse emissions. In fact, 10% of rich countries’ greenhouse gas emissions come from growing food that is never eaten. The water used globally to irrigate wasted food would be enough to meet the domestic needs of 9 billion people—the number expected on the planet by 2050.
