随身英语 The future of food production 食物生产的未来
Play audio file 随着新型机械不断地被发明,人们对劳动密集型耕作方式的依赖在逐日减少。然而,以下这一景象会成为现实吗?农民不再需要下地干活,机器人会承包所有的工作。这是英国及世界各地的科学家们正在尝试的一个想法。
课文内容 Vocabulary: technology 词汇: 科技 Imagine a future where all farming is done by machine, and humans never set foot in the fields.
No, it’s not science fiction. In Shropshire in the UK, engineers in the Hands Free Hectare project are developing automated tractors and fleets of drones to grow and harvest crops.
And their experiment is not alone: agricultural robotics is a booming sector. Investment bank Goldman Sachs estimates the market will be worth $240bn over the next five years.
One reason why the sector is on the up is that global demand for food is rapidly increasing. The World Bank estimates we will need to produce 50% more food by 2050 if the planet’s population continues to grow at its current speed. Add to this to the forecast that yields will decrease by over a quarter due to climate change, and the situation looks serious.
Could futuristic farming provide the answer?
One company in Japan believes so. The firm Spread has dispensed with farming on land altogether, and instead grows vegetables on stacks of trays indoors in an automated factory.
