At age 16, journalist and filmmaker Jose Antonio Vargas found out he was in the United States illegally. Since then, he's been thinking deeply about immigration and what it means to be a US citizen -- whether it's by birth, law or otherwise. In this powerful talk, Vargas calls for a shift in how we think about citizenship and encourages us all to reconsider our personal histories by answering three questions: Where did you come from? How did you get here? Who paid?
In her global exploration of Indigenous design systems, architect Julia Watson researches enduring innovations that could help us counter the challenges of climate change. From floating villages to living root bridges that strengthen over time, Watson introduces us to some of these resilient solutions -- and shows how they can teach us to design with nature, instead of against it.
We have archives of films, newspapers, even seeds -- what if we could make one for the entire surface of the earth? Drawing on his experience mapping an ancient city in the Honduran jungle, archaeologist Chris Fisher makes the case for scanning the whole planet with LiDAR -- a technology that uses lasers shot from an airplane to map the ground -- in order to preserve our cultural and ecological heritage.
Far-UVC light is a type of ultraviolet light that kills microbes and viruses and, crucially, seems to be safe to use around humans. Radiation scientist David Brenner describes how we could use this light to stop the spread of SARS-CoV-2, the virus responsible for COVID-19, in hospitals, nursing homes, trains and other public indoor spaces -- paving the way for a potentially game-changing tool in the fight against the coronavirus pandemic. (This virtual conversation, hosted by TED science curator David Biello, was recorded July 7, 2020.)
Reflecting on moments that shaped his life, actor Ethan Hawke examines how courageous expression promotes healing and connection with one another -- and invites you to discover your own unabashed creativity. "There is no path till you walk it," he says.
Yann LeCun, the chief AI scientist at Facebook, helped develop the deep learning algorithms that power many artificial intelligence systems today. In conversation with head of TED Chris Anderson, LeCun discusses his current research into self-supervised machine learning, how he's trying to build machines that learn with common sense (like humans) and his hopes for the next conceptual breakthrough in AI.
People everywhere are using Zoom to work, take classes, do yoga -- and even get married. The company's CEO and founder Eric Yuan reflects on how they developed the world's most popular video chat software and envisions a digital future that will include things like virtual handshakes and real-time language translations to rival face-to-face gatherings. (This virtual conversation, hosted by TED technology curator Simone Ross, was recorded July 6, 2020.)
"We are living through the tech-enabled unraveling of full-time employment itself," says anthropologist Mary L. Gray. As the pandemic exposes and accelerates the shift to on-demand online labor, Gray takes us inside the jobs being created to solve the problems artificial intelligence can't handle -- and explains why our economic recovery hinges on extending essential benefits to all workers. (This virtual conversation, hosted by TED business curator Corey Hajim, was recorded July 6, 2020.)
Crisis interventions often focus on a single aspect of a big, complicated problem, failing to address the broader social and economic context. Kwame Owusu-Kesse describes how the Harlem Children's Zone is taking a more holistic approach to the pandemic, weaving together a network of services to help communities recover and rebuild. Learn more about their comprehensive COVID-19 relief and recovery response focused on five primary areas of need -- and their plans to scale it across the US. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)
Poet and policymaker Aaron Maniam describes how the language we use to explain COVID-19 shapes the way we think about it -- whether it's as a "war," a "journey" or, as he suggests, an "ecology." He encourages us to explore a range of imaginative, interlocking metaphors to gain a deeper understanding of the pandemic -- and shows how this can help us to envision a better, more inclusive future. (This virtual conversation, hosted by TED's head of curation Helen Walters and arts and design curator Chee Pearlman, was recorded June 10, 2020.)
Civil rights leader and longtime US congressman John Lewis spent his life fighting for freedom and justice for everyone. In this illuminating conversation with lawyer and activist Bryan Stevenson, Lewis discusses the essential importance of voting, shares encouraging words of wisdom for the generation of young people currently organizing in the struggle for racial justice and tells moving stories from his decades of making "good trouble" -- at the Freedom Rides, March on Washington and in the halls of Congress. "When you see something that's not right or fair or just, you have to say something," Lewis says. "You have to do something." (This conversation is part of the TED Legacy Project. Recorded November 19, 2019)
On July 20, 2012, a mass shooting in a movie theater of Aurora, Colorado left the town, and its nation, reeling. To many -- including Tom Teves, who lost his son in the tragedy -- the news coverage that followed focused on all the wrong things. Why did the reporting overwhelmingly fixate on the shooter rather than the lives of the victims or the heroic efforts of first responders? With urgency and measure, Teves calls for responsible media attention that acts in the interest of the public (instead of profit) by revoking what shooters want most: infamy.
Investors tend to think in daily and quarterly numbers, leading to a system that can harm the future health of the economy and planet. Michelle Greene explains how the Long-Term Stock Exchange is reimagining public markets by holding companies to forward-thinking standards of diversity and inclusion, employee investment and environmental responsibility -- and generating better outcomes for everyone involved. (This virtual conversation, hosted by TED business curator Corey Hajim, was recorded June 24, 2020.)
What does Kendrick Lamar have in common with Disney's "Moana"? They recognize our common humanity and show us how to love ourselves and one another, says writer and educator Chlo√© Valdary.

(This virtual conversation, hosted by TED business curator Corey Hajim, was recorded June 30, 2020.)
What if you could help decide how the government spends public funds in your community? That's the idea behind participatory budgeting, a process that brings local residents and governments together to develop concrete solutions to real problems close to home. In this inspiring call to action, community leader Shari Davis shows how participatory budgeting can strengthen democracy, transform neighborhoods and cities -- and give everyone a seat at the table. "We've got to open the doors to city halls and schools so wide that people can't help but walk in," she says.
A more equal world starts with you. Citing a formative moment from her own life, equity advocate Nita Mosby Tyler highlights why showing up and fighting for others who face injustices beyond your own lived experience leads to a fairer, more just future for all.
"If you change your city, you're changing the world," says Eric Garcetti, mayor of Los Angeles and chair of C40 Cities, a network of the world's megacities committed to tackling the climate crisis. He shares tangible ways Los Angeles and other cities across the globe are promoting economic and social justice while taking concrete action on climate change -- and talks about how to create a more inclusive, green and sustainable society as we rebuild from COVID-19. (This virtual conversation, hosted by TED's current affairs curator Whitney Pennington Rodgers, was recorded July 7, 2020.)
With clarity and insight, economist and author William "Sandy" Darity discusses how the grievous injustice of slavery in the US led to the immense wealth gap that currently exists between Black and white Americans. He explains how reparations for descendants of enslaved people would work -- and why it's necessary that the US engage in this act of compensation and redemption to make progress towards true equality. (This virtual conversation, hosted by TED's current affairs curator Whitney Pennington Rodgers, was recorded June 30, 2020.)
In this tour of the microscopic world, explorer and artist Ariel Waldman introduces the charismatic creatures lurking beneath Antarctica's massive ice sheet, the largest on earth. From "cuddly" water bears to geometric algae made of glass, Waldman shows how this seemingly barren landmass is actually a polar oasis of life -- if we just know where to look.
