带领大家进行一趟简短的旅程
这种森林经砍伐后的鱼骨状图案
穿过一道类似细缝的地方
数年后-2003年的景观
较多植物性蛋白质喂食动物
河水用来灌溉沙漠中的作物
同样地,我们开采水源
或许记得地理课中曾经学过
而是环境本质上的改变
(美国前副总统)给我的一张照片
这些东西,将这个时代的情形
疑惑地想,“你们到底在想什么?”
并非奢侈品,而是不可或缺的需求
供应世上70亿人口所需
消耗更多粮食、更多资源
潜在农业用地,假设气候变迁
新贸易补贴法案、新农业法案-
2040年全球将拥有90亿人口
逐渐增长的人口,而不对地球造成破坏?
+生质能源生产=自然资源面临的压力
水量相当于2800立方公里
农业是造成气候变迁的最大因素
更大规模的沟通、全球性的对话
新型作物、滴水灌溉系统
更佳的耕作方式、更睿智的饮食型态
