You don't need political power to make real change, says activist Katie Fahey. She tells the story of how she led a successful movement in Michigan to end gerrymandering — the practice of drawing district lines to favor one political party — and how it all started with a simple social media post.

A landfill on fire doesn't only emit a horrid stench — it has devastating consequences for the environment, too. The culprit is methane, an often underestimated greenhouse gas produced in large part by food systems, organic waste and yes, cow burps. Biochemical engineer Marcelo Mena explains the source of this sneaky pollutant, why its emissions need to be cut in half by 2050 — and what you can do to help.

Drawing on his decades-long mission to formulate the world in computational terms, Stephen Wolfram delivers a profound vision of computation and its role in the future of AI. Amid a debut of mesmerizing visuals depicting the underlying structure of the universe, he provides a sweeping survey of his life's work, offering a new perspective on the applications — and consequences — of AI powered by computational language.

Electric vehicles need to be more than just eco-friendly — they have to be more chic, convenient and affordable than their gas-powered alternatives, says sustainability leader Cynthia Williams. She explores what it'll take for an electric revolution to succeed in the US, calling on corporations, policy leaders, investors and more to collaborate in unprecedented ways.

The vast majority of our time at work is spent trudging through redundant and outdated workflows, says operations visionary Salvatore Cali. Laying out the most common time-wasting pitfalls, he urges policy leaders and businesses to reevaluate what they ask of both employees and consumers. "By rethinking the true purpose of each task, you will discover what is waste and what is the real gold of your company: the creation of value," says Cali.

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water heaters.) If we're going to fix this problem, we need to retrofit millions of buildings with all-electric equipment, says energy upgrader Donnel Baird. Hear about his ambitious plan to rip the fossil fuel infrastructure out of aging buildings and upgrade it with smarter, cleaner, healthier technology.

Environmental activist Gopal D. Patel thinks the climate movement could learn a lot from one of the longest-standing social initiatives in human history: religion. Exploring three areas where frameworks from faith traditions could benefit the climate movement, Patel offers a playbook for discovering your big idea to build momentum towards powerful social change.

Irina Karamanos Adrian didn't plan on becoming Chile's First Lady — but she set out to transform the role all the same. She shares how she's fighting gender stereotypes and protecting democracy by shifting political power back to where it belongs: to people who were actually elected.

Material scientist Anna Maria Coclite unveils "smart skin" — artificial skin technology that responds to touch, temperature and humidity like your very own. (It's actually even more sensitive than human skin!) From helping burn victims to paving the way to smarter, safer humanoid robots, Coclite highlights the broad-ranging potential of this innovation.

Artist Doris Mitsch invites us to revel in the wonders of nature through her dazzling photography: stacked images of starlings in flight, hawks surfing thermal updrafts, bats echolocating through the night sky and more. Revealing the hidden trails created by creatures in flight, her work offers unique insight into the intelligence behind nature's invisible rhythms.

When it comes to technology, we're often presented with two contrasting visions of the future: one where technology fulfills all our desires, and another where it leads to chaos and conflict. Sociologist Ruha Benjamin is here with a more radical vision of the future — one where humanity isn't saved or slayed by technology, but rather uses it to uplift ordinary people and make things like health care and housing for all a reality.

The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future, their production is surprisingly harsh on the environment. She lays out the science behind a breakthrough in recycling a battery's core elements, offering a manufacturing solution that could vastly reduce the industry's environmental impact and demand for new materials from mining.

From World War II to the 2008 economic collapse and beyond, history shows that economists don’t always see the future as clearly as they think they do, says David McWilliams. Using the words of W.B. Yeats, McWilliams makes the case for embracing unconventional thinkers – poets, artists and musicians – and offers a creative path towards a world filled with less confirmation bias and more understanding.

AI won't kill us all — but that doesn't make it trustworthy. Instead of getting distracted by future existential risks, AI ethics researcher Sasha Luccioni thinks we need to focus on the technology's current negative impacts, like emitting carbon, infringing copyrights and spreading biased information. She offers practical solutions to regulate our AI-filled future — so it's inclusive and transparent.

There's a saying that comedy is tragedy plus time. Perhaps that's why some of our biggest problems feel easiest to manage with a dose of humor. Comedian, journalist and actor Roy Wood Jr. has spent his career finding the silly in the serious and using this tactic to influence real change. Listen in to learn how you can tap into the powers of humor in your own life. (This conversation, hosted by comedian Chris Duffy, was part of an exclusive TED Membership event.

US Congresswoman Lucy McBath has made it her mission to seek bipartisan solutions for gun safety, leading the way in sponsoring so-called “red flag” laws that prevent gun violence and mass shootings. In a searing and timely talk, she shares the personal story that led her to this work — and a message for why comprehensive, common-sense gun legislation in the US is more urgent than ever.

Using paychecks, perks and carefully worded mission statements plastered on posters, companies are on a never-ending quest to find what drives morale at work. An underappreciated solution lies in the answer to one simple question, says management researcher David Burkus. With notable examples backed by decades of success, he presents a clear path to inspiring your team — and finding your purpose at work.

Our culture is obsessed with happiness, but what if there's a more fulfilling path? Happiness comes and goes, says writer Emily Esfahani Smith, but having meaning in life -- serving something beyond yourself and developing the best within you -- gives you something to hold onto. Learn more about the difference between being happy and having meaning as Esfahani Smith offers four pillars of a meaningful life.
