Even with public trust at an all-time low, Wikipedia continues to maintain people's confidence. How do they do it? Former CEO of Wikimedia Foundation Katherine Maher delves into the transparent, adaptable and community-building ways the online encyclopedia brings free and reliable information to the public -- while also accounting for bias and difference of opinion. "The seeds of our disagreement can actually become the roots of our common purpose," she says.

Air travel opens our eyes to the world, but it also comes at a high cost to the environment. Piloting us into a future of green aviation, innovator Ryah Whalen shares three ways to lower the industry's carbon footprint through smarter designs, eco-friendly fuel and new technology -- so we can continue to explore the planet without hurting it.

"If we can unlock the full potential of our cities, we can minimize the price the planet pays for hosting us in our growing numbers," says Marvin Rees, the Mayor of Bristol, UK, who understands deeply how cities can help (or hurt) the environment. Rees notes that while sustainable infrastructure already exists in many parts of the world -- like electric buses in Colombia and freshwater reserves in Singapore -- major investments could make similar innovations more far-reaching and successful. He highlights the pivotal role of city mayors in advocating for a "worldwide network of efficient decarbonized cities" that will bring the world closer to its climate goals.

Linking together the histories of Henrietta Swan Leavitt, Edwin Hubble and Tracy K. Smith, poet and thinker Maria Popova crafts an astonishing story of how humanity came to see the edge of the observable universe. (Followed by an animated excerpt of "My God, It's Full of Stars," by Tracy K. Smith)

The weekend. Social security. Health insurance. What do these things have in common? They're all thanks to the advocacy of labor unions. Political economist Margaret Levi explains how these organizations forge equality and protect worker rights, calling for a 21st-century revival of the labor movement in order to build a more equitable future.

In a talk packed with wry wisdom, pop culture queen Bevy Smith shares hard-earned lessons about authenticity, confidence, mature success and why, if you put in the work, "life gets greater later."

Lighting up the TED stage, Nobel laureate Al Gore takes stock of the current state of climate progress and calls attention to institutions that have failed to honor their promises by continuing to pour money into polluting sectors. He explains how the financial interests of fossil fuel companies have blocked the policymaking process in key countries -- and calls for a global epiphany to take on the climate crisis. "Do not give up hope," Gore says. "And remember always that political will is itself a renewable resource."

In times of uncertainty, leaders have a responsibility to inspire hope. Sharing hard-won wisdom, business leader Ken Chenault talks about what it takes to enact positive, enduring change -- and why it's more important than ever to invest in responsible innovation that uplifts people and centers equality and fairness. (This conversation was hosted by TED current affairs curator Whitney Pennington Rodgers.)

Corporate inclusion visionary Deepa Purushothaman shares how women of color can advocate for themselves in workplace settings where they are undervalued, discriminated against and overlooked -- and how companies can foster working cultures that empower everyone to achieve success.

Are you actually busy, or do you just feel busy? The answer matters because it could change how you move through your daily life. Leadership expert Dorie Clark shares the three reasons people fall into an endless loop of feeling constantly busy, and invites you to question what really motivates how you spend your time.

As digital assets like cryptocurrency and NFTs become more mainstream, design thinker and head of Instagram Adam Mosseri believes that creators are uniquely positioned to benefit. These blockchain-enabled technologies could remove the need for a "middleman" in the form of large social media platforms, allowing creators to more freely distribute their work and connect with their audiences. He explains how this new age of the internet will give way to "the greatest transfer of power from institutions to individuals in all time."

Conservation efforts in Africa have typically been led by "parachute conservationists" -- outsiders who drop in thinking they have all the answers, hire locals to implement them and then disappear. But conservationist Resson Kantai Duff has a better way to save wildlife in Africa: let locals lead these efforts themselves. She calls for a major shift in how conservation in Africa works, showing why the people closest to the land are the ones best fit to care for it.

Organized crime operates across national borders -- to keep up, investigative journalists need to do the same. TED Fellow Bektour Iskender gives the inside scoop on his efforts to unveil secret, insidious operations in his home country of Kyrgyzstan, and how he worked with a team of journalists to uncover corruption and spark a national movement. He shares three key insights on how global networks of investigative journalists protect the world not just from smugglers and thieves but from dictators and warmongers.

Money is pollution's biggest driving force -- particularly, the cash invested in dirty energy projects, says financial responsibility campaigner Lucie Pinson. She shares a three-pronged approach to stop banks from funding fossil fuel companies, including what she calls "collaborative blackmailing" (it's more ethical than it sounds). By demanding more accountability from polluting companies and encouraging ethical banking, Pinson shows how to cut off the problem at its source.

The traditional approach to work needs a redesign, says economist Juliet Schor. She's leading four-day work week trials in countries like the US and Ireland, and the results so far have been overwhelmingly positive: from increased employer and customer satisfaction to revenue growth and lower turnover. Making the case for a four-day, 32-hour work week (with five days of pay), Schor explains how this model for the future of work could address major challenges like burnout and the climate crisis -- and shares how companies and governments could work together to make it a reality.

There are 600 million women in India -- yet they are rarely seen outdoors after sunset because of safety concerns like harassment and catcalls. On a mission to create safer public spaces, women's rights advocate Srishti Bakshi talks about how she embarked on a 2,300-mile walk across the length of India (a distance equivalent to traveling from New York City to Los Angeles), conducting driving workshops to empower women's mobility across the country. "The more women see other women in public spaces, the more safe, independent and empowered each of us will be," Bakshi says.

Many people across the world don't have access to healthy food -- while in other places tons of food go to waste. Social entrepreneur Ndidi Okonkwo Nwuneli thinks we can take bold steps to fix this problem. She lays out what it would take to build a more equitable, sustainable food system that nourishes all people and asks us to widen our perspectives before eating our next meal.

Whether we're rushing a child to the emergency room after a fall or making chicken soup for a feverish spouse, love inspires us to act when a family member gets sick. Global health activists Edith Elliott and Shahed Alam believe we can harness this power to create better health outcomes for everyone. Learn how their organization Noora Health works with doctors and nurses in India and Bangladesh to train the family members of hospital patients with essential skills to support their sick loved ones -- and how they plan to expand their reach to support 70 million caregivers who care for more than one billion people over the next six years.

Digital public servant Amanda Renteria has seen that the millions of people who rely on government welfare services are often discouraged from seeking them out, frustrated and discouraged by long lines and unnecessarily complicated processes. At Code for America, Renteria is helping develop human-centered technology that "respects you from the start, meets you where you are and provides an easy, positive experience." She details the four factors that hinder effective delivery of government benefits and explains Code for America's plan to bring user-centric, digital-first social services to more than 13 million Americans and unlock $30 billion in benefits for low-income families. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

A safe space to save money is life-changing -- especially for the 60 million smallholder farmers in West Africa (the majority being women) who often live on less than two dollars a day. Poverty fighter Anushka Ratnayake introduces her non-profit myAgro, which offers farmers a place to save small amounts of money and allows them to access those funds as they need them. Over the next five years, myAgro plans to reach a million farmers in West Africa, providing a stress-free, transparent and convenient system that empowers agricultural entrepreneurs by putting the purchasing power it takes to run a successful farm in their hands. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

Election infrastructure in the United States is crumbling, says technologist Tiana Epps-Johnson, and, even worse, election officials are increasingly being attacked simply for doing their jobs. How can the country rebuild trust in its local and national elections? Epps-Johnson describes how the US Alliance for Election Excellence, a nonpartisan collaborative of election officials, technologists, designers and other experts, is working across all 50 states to improve the performance of systems serving 240 million voters, ensuring everyone has access to a fair, trustworthy and modern democratic process. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

In Latin American countries like El Salvador, where local changemaker Celina de Sola lives, homicide rates are alarmingly high due to a vicious cycle of violence where people don't have an opportunity to heal from individual and collective trauma. With her team at Glasswing International, de Sola is hoping to break this cycle by equipping government employees like teachers and police officers with the skills and knowledge they need to provide mental health care to those who need it most. Their goal: to transform more than 2,000 frontline institutions in 25 of the highest-risk municipalities in Central America with community-based approaches to mental health support, reaching nearly 10 million people along the way. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

What will happen to the planet if climate change melts what's left of Arctic permafrost? Shedding light on this overlooked threat, Arctic geologist Sue Natali reveals the true danger of heating up the iciest place on the planet: the release of ancient carbon that will dramatically worsen our climate problems. In this urgent talk, she introduces a new initiative, Permafrost Pathways, and their work to measure permafrost carbon emissions, fuse Indigenous solutions with modern technologies and protect the rights of Arctic residents. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

Indigenous communities have looked after their ancestral forests for millennia, cultivating immense amounts of knowledge on how to protect, nourish and heal these vital environments. Today, 470 million Indigenous people care for and manage 80 percent of the world's biodiversity -- yet their legal rights to these lands are inexplicit and subject to exploitation by illegal loggers, miners and companies. Human rights lawyer Nonette Royo describes how her team at the Tenure Facility, an organization that provides legal assistance to Indigenous people by taking their land rights battles to court, will help these communities secure and defend 50 million hectares of forests over the next five years. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)

"Human migration is both inevitable and growing. What are we as a global community doing to address it?" asks human rights lawyer Becca Heller, who believes that every refugee and migrant deserves a safe pathway to resettlement. Through her work with the International Refugee Assistance Project (IRAP), Heller is showing how the power of the law can help displaced people find homes. By providing access to legal information and services, IRAP champions a functional, rights-based legal system that empowers resettlers to find long-lasting safety. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change. If you want to hear even more about Heller's work, stick around after the talk on the "TED Talks Daily" podcast, where she digs deeper into her ideas.)

How do we define worth in society, and who gets status? Sociologist Michele Lamont studies these questions and investigates ways to broaden the circle of recognition and fight the harm of social stigmatization. She lays out the steps needed to make more inclusive societies -- and it all starts by expanding our idea of who matters.

Tattoos can transform and empower people, with some seeking them out to reconnect with their bodies due to scarring, physical abnormalities or the aftermath of a procedure or illness. Paramedical tattooist Becky Barker shares the art and craft of medical tattooing, explaining how this expansive field helps improve the quality of life for breast cancer survivors -- and anyone looking to renew themselves in ways that are more than skin-deep.

The secret behind medicines that use messenger RNA (or mRNA) is that they "teach" our bodies how to fight diseases on their own, leading to groundbreaking treatments for COVID-19 and, potentially one day, cancer, the flu and other ailments that have haunted humanity for millennia. RNA researcher Melissa J. Moore -- Moderna's chief scientific officer and one of the many people responsible for the rapid creation and deployment of their COVID-19 vaccine -- takes us down to the molecular level, unraveling how mRNA helps our bodies' proteins maintain health, prevent disease and correct errors in our genetic code. "We have entered an entirely new era of medicine," Moore says.

"It is time to close the funding gap for Black female-led start-ups the world over," says entrepreneur Temie Giwa-Tubosun, whose company LifeBank delivers life-saving medical supplies to remote areas in Africa. Today, LifeBank operates successfully across the continent, but Giwa-Tubosun knows that barriers to funding prevent many other brilliant business ideas from blossoming. She highlights examples of impactful women-led ventures around the world -- and challenges investors to help more of them thrive.

The James Webb Space Telescope is a miracle of modern science and engineering. With a 21-foot, gold-coated mirror protected by a sunshield that's the size of a tennis court, it's the world's most powerful telescope and humanity's latest attempt to answer questions like: "Where did we come from?" and "Are we alone?" (It also needed to be folded up like origami in order to launch into space.) Nobel Laureate John C. Mather, the leader of the team at NASA that built the Webb, explains how the telescope will observe the first galaxies to form in the early universe, peer behind clouds of cosmic dust and gas to reveal stars being born and uncover new details about places like Europa and Titan, which could harbor life. "We're going to get a great surprise from this telescope," Mather says.

What happens when the data-driven capabilities of AI are combined with human creativity and ingenuity? Shining a light on the opportunities this futuristic collaboration could bring to the workplace, AI expert Shervin Khodabandeh shares how to redesign companies so that people and machines can learn from each other.

Building a pandemic-free future won't be easy, but Bill Gates believes that we have the tools and strategies to make it possible -- now we just have to fund them. In this forward-looking talk, he proposes a multi-specialty Global Epidemic Response and Mobilization (GERM) team that would detect potential outbreaks and stop them from becoming pandemics. By investing in disease monitoring, research and development as well as improved health systems, Gates believes we can "create a world where everyone has a chance to live a healthy and productive life -- a life free from the fear of the next COVID-19."

To solve the climate crisis, we need to make tropical forests worth more alive than dead, says environmental economist Nat Keohane. Highlighting the urgent need to stop deforestation and the carbon pollution it brings, he details the work of the LEAF Coalition -- a first-of-its-kind public-private partnership that's channeling one billion dollars into protecting tropical forests -- and shares three building blocks for a robust market for forest carbon that enables economies to thrive while protecting natural resources.

Getting pregnant as a track and field athlete is often called the "kiss of death" -- a sign your athletic career will soon end. Olympic champion, entrepreneur and proud mother Allyson Felix thinks it shouldn't be that way. She tells the story of starting a family while fighting to change her former sponsor's maternity policy -- and paving the way for others to get greater protection and more support. Her message is a testament to the power of believing in and advocating for yourself. "You don't have to be an Olympian to create change for yourself and others," she says. "Each of us can bet on ourselves."

What's on Elon Musk's mind? In conversation with head of TED Chris Anderson, Musk details how the radical new innovations he's working on -- Tesla's intelligent humanoid robot Optimus, SpaceX's otherworldly Starship and Neuralink's brain-machine interfaces, among others -- could help maximize the lifespan of humanity and create a world where goods and services are abundant and accessible for all. It's a compelling vision of a future worth getting excited about. (Recorded at the Tesla Texas Gigafactory on April 6, 2022)

In this unedited conversation with head of TED Chris Anderson, Elon Musk digs into the recent news around his bid to purchase Twitter and gets honest about the biggest regret of his career, how his brain works, the future he envisions for the world and a lot more. (This conversation was recorded April 14, 2022. If you want to hear even more, head over to The TED Interview podcast, where Musk and Anderson sat down at the new Tesla gigafactory in Texas to discuss some of the radical innovations he's working on -- including an intelligent humanoid robot, SpaceX's Starship and Neuralink's brain-machine interfaces.)

The Russian invasion of Ukraine has destroyed so much -- including hundreds of schools, where the country's children were forging their futures -- but it has not stopped Ukrainians from pursuing knowledge and curiosity. In a deeply moving talk, education leader Zoya Lytvyn shares her first-hand experience evacuating Kyiv and takes us inside the ongoing effort to continue educating children amid war and destruction. "As long as our children keep learning and our teachers keep teaching -- even while they are starving in shelters under bombardment, even in refugee camps -- we are undefeated," she says.

When women lead, bias often follows. Documentarian Robin Hauser dives into the dilemma between competence and likeability faced by women in leadership roles, detangling the unconscious beliefs and gendered thinking that distort what it means to be a good leader.

Ukraine is on the front line of a war between freedom and tyranny, says chess grandmaster and human rights advocate Garry Kasparov. In this blistering call to action, he traces Vladimir Putin's rise to power and details his own path from chess world champion to pro-democracy activist in Russia. His message is a challenge to global leaders to rise in support of Ukraine -- and to choose life and love over death and hatred. "The price of stopping a dictator always goes up with every delay and every hesitation," he says. "Meeting evil halfway is still a victory for evil."

"Life makes our planet an incredibly exotic place compared to the rest of the known universe," says astrobiologist Betül Kaçar, whose research uses statistics and mathematical models to simulate ancient environments and gather insights into the origins of existence. In this fascinating talk, she explores how a deeper understanding of chemistry could lead to the "secret sauce" for sparking life on other planets -- and asks us to ponder an important question: If we could kick-start life in the universe, should we?

"Music can unlock a frozen memory that melts into the seeds of our creativity," says musician Rosanne Cash. Reflecting on the power of memory, solitude and community, she performs "The Sunken Lands" and "Particle And Wave" and meditates on some of life's most poignant and bittersweet themes.

Given the scale of the challenge, the conversation around climate change is often tinged with doom and gloom.

Performing two original songs, stand-up comedian, writer and musician Marcia Belsky shares comical commentary on some peculiar aspects of our culture -- from Instagram-stalking your crush to fending off mansplainers on social media -- and lampoons NASA's notorious decision to provide astronaut Sally Ride with an egregious supply of tampons for her six-day trip to space in 1983.

Living under the constant threat of violence has a lasting effect -- even after you escape from danger, says writer and refugee advocate Zarlasht Halaimzai. One of the millions of people worldwide who have been forcibly displaced by conflict, Halaimzai now helps others overcome the devastation of war. In this poignant, vital talk, she articulates the lingering trauma of being expendable -- and shares how belonging to a community can help bring back feelings of long-lost safety.

Pop culture is changing thanks to a different kind of storytelling, says digital strategist Hyeonmi Kim. They're called webtoons: comic-like illustrations published in short segments and meant to be read on a smartphone in five to 10 minutes. Kim breaks down how webtoons have leapt from phones to the big screen (Netflix's "Hellbound," anyone?) and how they're bringing a new, diverse generation of creators into TV and movie scriptwriting.

After leading a well-established life as a pastor, father and husband, Paula Stone Williams could no longer deny her truth and transitioned. In this conversational and at times humorous reflection, Williams offers her perspective on the everyday experiences lost, gained and once taken for granted in her journey of trans womanhood.

What if smallholder farmers could use their produce and livestock to pay for goods and services? TED Fellow and alternative currency enthusiast Fariel Salahuddin is working to make this a reality in places including rural Pakistan, where basic necessities like water and electricity are often expensive or inaccessible. She explores how the way we exchange value has evolved over time -- from bartering to blockchain -- and shares a new perspective on currency that promotes self-reliance for farmers and creates a more inclusive economy.

Evoke a familiar tune in a song and get slapped with a lawsuit ... it's a tale almost as old as copyright itself. Lawyer and technologist Damien Riehl digs into why "owning" a melody is a ludicrous legal assertion and composes a radical solution for the musical woes of songwriters everywhere.

The peatlands of Africa's Congo Basin are a vast expanse of swamp and greenery that act as one of the world's most effective carbon sinks -- and they're under threat of environmental destruction. Economist Vera Songwe explains how putting a price on the carbon stored in the peatlands would not only help protect this vital resource but also recognize and reward the African communities that have contributed little to climate change. "This is not just about decarbonization," Songwe says. "This is also about development with dignity."
