　　The future of agriculture must achieve several goals at the same time．

　　First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels （生物燃料） We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture’s impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world’s poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the under-nourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our high-efficiency, globalized world has many benefits, but it is vulnerable （易受伤的） to destruction, whether from droughts, diseases or sudden price rises． We must start building better food systems to better keep us away from future shocks．
