We're living through oil wars, wildfire smoke and extreme weather driven by a warming planet. But environmentalist Bill McKibben says one thing is finally going right: the price of clean energy has plunged, making it cheaper than ever to power the world without burning fossil fuels. He breaks down how energy from the sun became the best option on Earth -- and why this narrow window of time may be our last real shot at a different future. "Energy from heaven, not from hell," he says. 
我们正经历着石油战争、野火烟雾，以及全球变暖引发的极端天气。但环保主义者比尔·麦吉本（Bill McKibben）指出，有一件事终于走上了正轨：清洁能源的价格大幅下降，让不燃烧化石燃料为世界供电变得比以往任何时候都更加便宜。他详细分析了太阳能如何成为地球上最佳选择——以及为什么这个稍纵即逝的时间窗口，可能是我们实现不同未来的最后一次真正机会。“来自天堂的能量，而非来自地狱，”他说道。

If you ate bread this week (or cooked with salt and oil), you probably benefited from something millions miss out on: food fortification. Social entrepreneur Felix Brooks-church is on a mission to solve "hidden hunger" -- malnutrition caused by a lack of nutrients -- by fortifying everyday foods for regions of the world hit hardest by food insecurity. Laying out a pragmatic vision to improve food systems globally, he reminds us that hunger doesn't always look like an empty plate.
如果你这周吃过面包（或是烹饪时用了盐和食用油），那你或许已经受益于一项数百万人无缘享用的举措：食物强化。社会企业家费利克斯・布鲁克斯 - 彻奇（Felix Brooks-church）致力于解决 “隐性饥饿”—— 也就是营养素缺乏引发的营养不良问题。他的办法是，在粮食安全问题最严峻的地区，给日常主食添加营养素。他提出一套务实的构想，意在改善全球粮食体系，并提醒我们：饥饿，未必总是表现为空空如也的餐盘。
