When entrepreneur Yi Li cofounded Farmworks, she set out to build 1,000 climate-smart farms across Kenya, complete with dams, irrigation and organic fertilizers. The science was sound, but reality proved more complicated. Learn what she discovered about the missing ingredient behind failed climate solutions — and how it challenges a core assumption of the environmental movement on how to create lasting impact.
企业家李艺（Yi Li）联合创立农田工坊（Farmworks）之初，立志在肯尼亚打造 1000 座气候智慧型农场，配套修建水坝、灌溉系统，并推广有机肥料。这套方案理论依据充分，现实落地却错综复杂。一起来了解：她发现了气候治理方案屡屡失败背后，究竟缺失了关键一环；以及这一发现，如何颠覆环保运动界关于实现长效影响的核心固有认知。

OpenClaw creator Peter Steinberger takes us back to the transformative moment he let his AI agent loose on the internet, igniting one of the world's fastest-growing open-source projects. He makes a fascinating (and slightly unnerving) case that agents are a real shift, not just better versions of chatbots, and explores how they might reshape your ability to work, build and create. "The lobster is loose, and it's not going back into the tank," he says. (Followed by a brief Q&A with TED Chairman Chris Anderson)
OpenClaw 的创始人彼得·斯坦伯格（Peter Steinberger）带我们回到那个他把 AI 代理释放到互联网上、点燃了全球增长最快的开源项目之一的变革性时刻。他提出了一个引人入胜（且略显不安）的观点：代理技术不仅是聊天机器人的升级，而是一场真正的变革，并探讨它们如何重塑我们工作的方式、构建和创造的能力。
“龙虾已经逃逸，已经无法再回到水槽里，”他如是说。
（随后简短的 Q&A 环节，与 TED 主席克里斯·安德森（Chris Anderson）对话。）

As a child in rural Kenya, conservationist Seif Hamisi fell asleep to the sound of lions outside his village. Today, the lions are gone, mirroring a continent-wide trend: African wildlife populations have plummeted in recent decades, despite billions spent to protect nature. Drawing on examples of successful conservation efforts from the grasslands of South Africa to the woodlands of Kenya, he shows how we've been attempting to solve the wrong problem — and makes the case that conservation works best when it makes economic sense.
小时候在肯尼亚农村，保护主义者赛夫·哈米西（Seif Hamisi）在村子外的狮子声中睡着了。今天，狮子已经消失了，这反映了整个大陆的趋势：尽管花费了数十亿美元来保护自然，但近几十年来，非洲野生动物的数量急剧下降。他借鉴了从南非草原到肯尼亚林地的成功保护工作的例子，展示了我们如何试图解决错误的问题——并认为保护在经济上有意义时效果最好。

You spend weeks studying for an important test. On the big day, you wait nervously as your teacher hands it out. You're working your way through, when you're asked to define "ataraxia." You know you've seen the word before, but your mind goes blank. What just happened? Elizabeth Cox details the complex relationship between stress and memory. [TED-Ed Animation by Artrake Studio]
你花了几周时间准备一场重要的考试。大考之日，你紧张地等待老师分发试题。你往下做题，发现一道题目要求解释“ataraxia”。你知道自己见过这个词，但是大脑却一片空白。发生了什么？伊丽莎白·考克丝（Elizabeth Cox）详细讲述了压力和记忆之间的复杂关联。

Investigative journalist Katherine Eban set out to report on a seemingly straightforward question: Are generic drugs really identical to their brand-name counterparts? The answer sparked a decade of interviews, meetings with whistleblowers, on-the-ground reporting across four continents and digging into confidential FDA documents. In this alarming talk, she takes us inside overseas manufacturing plants and exposes the fraud behind many low-cost generic medicines.
调查记者凯瑟琳·艾班（Katherine Eban）开始着手报道一个看似直接的问题：仿制药是否真正等效于它们的同名品牌药？寻找这个问题的答案激发了长达十年的采访、与知情者的会面、跨越四大洲的实地探访，以及对美国食物及药品管理局（FDA）机密文件的深入调查。在这次令人警醒的演讲中，她带我们进入海外的制药厂，并揭露了许多廉价仿制药背后的欺诈。

Llion Jones cowrote "Attention Is All You Need," the seminal paper that introduced the transformer — the architecture that launched the generative AI revolution. Now he warns that the industry that grew out of this breakthrough is stifling the next one. Learn why the current corporate arms race is killing true innovation and how we can get back to bold exploration.

Deep beneath the Earth sits 50,000 times more energy than all the world's fossil fuel reserves, but accessing it requires using the same controversial technology that oil companies spent trillions to develop: fracking. Cindy Taff left Shell to prove that drilling for geothermal heat instead of hydrocarbons can deliver what solar, wind and fossil fuels can't — clean, renewable power at all times, regardless of weather. Could this be the breakthrough that finally solves our energy challenges?
地球深处蕴藏的能量，相当于全球所有化石燃料储量的五万倍，但要开发这种能源，必须用到石油公司斥资数万亿美元研发的同一项争议性技术——水力压裂法。辛迪·塔夫（Cindy Taff）离开壳牌公司，就是为了证明：钻探开采地热，而非碳氢化合物，能够实现太阳能、风能与化石燃料都无法做到的事——无论天气如何，全天候提供清洁、可再生的电力。这会成为最终破解人类能源难题的重大突破吗？
