If you're not already a fan of earth's feathermakers -- or concerned about their conservation -- you will be after you watch this delightful talk.
Congratulations! By being here, alive, you are one of history's winners -- the culmination of a success story four billion years in the making. The other 99 percent of species who have ever lived on earth are dead -- killed by fire, flood, asteroids, ice, heat and the cold math of natural selection. How did we get so lucky, and will we continue to win? In this short, funny talk, paleobiologist and TED Fellow Lauren Sallan shares insights on how your ancestors' survival through mass extinction made you who you are today.
Are diverse companies really more innovative? Rocío Lorenzo and her team surveyed 171 companies to find out -- and the answer was a clear yes.

In a hopeful, funny talk, Bynum shares how he's tackling his city's most pressing issues and says that we need to set aside philosophical disagreements and focus on the aspirations that unite us.
Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air.

Machines that can think, learn and adapt are coming -- and that could mean that we humans will end up with significant unemployment. What should we do about it? In a straightforward talk about a controversial idea, futurist Martin Ford makes the case for separating income from traditional work and instituting a universal basic income.
Margrethe Vestager wants to keep European markets competitive -- which is why, on behalf of the EU, she's fined Google $2.8 billion for breaching antitrust rules, asked Apple for $15.3 billion in back taxes and investigated a range of companies, from Gazprom to Fiat, for anti-competitive practices. In an important talk about the state of the global business, she explains why markets need clear rules -- and how even the most innovative companies can become a problem when they become too dominant. "Real and fair competition has a vital role to play in building the trust we need to get the best of our societies," Vestager says. "And that starts with enforcing our rules."

In this quick talk about a big idea, Sheldrick explains the economic and political implications of giving everyone an accurate address -- from building infrastructure to sending aid to disaster zones to delivering hot pizza.
One in five women in the United States will not have a biological child, and Christen Reighter is one of them. From a young age, she knew she didn't want kids, in spite of the insistence of many people (including her doctor) who told her she'd change her mind. In this powerful talk, she shares her story of seeking sterilization -- and makes the case that motherhood is an extension of womanhood, not the definition.

In a talk equal parts funny and smart, he brings his wisdom from the ring to everyday life, sharing how we can all live more confidently and reach our full potential.
A war zone can pass for a mostly peaceful place when no one is watching, says investigative journalist and TED Fellow Anjan Sundaram. In this short, incisive talk, he takes us inside the conflict in the Central African Republic, where he saw the methodical preparation for ethnic cleansing, and shares a lesson about why it's important to bear witness to other people's suffering. "Ignored people in all our communities tell us something important about who we are," Sundaram says. "A witness can become precious, and their gaze most necessary, when violence passes silently, unseen and unheard."
In the vast sweep of history, even an empire can be forgotten. In this wide-ranging talk, Gus Casely-Hayford shares origin stories of Africa that are too often unwritten, lost, unshared.

"From populist demagogues, we will learn the indispensability of democracy," says novelist Elif Shafak. "From isolationists, we will learn the need for global solidarity. And from tribalists, we will learn the beauty of cosmopolitanism." A native of Turkey, Shafak has experienced firsthand the devastation that a loss of diversity can bring -- and she knows the revolutionary power of plurality in response to authoritarianism. In this passionate, personal talk, she reminds us that there are no binaries, in politics, emotions and our identities. "One should never, ever remain silent for fear of complexity," Shafak says.

After decades of research and billions spent in clinical trials, we still have a problem with cancer drug delivery, says biomedical engineer Elizabeth Wayne. Chemotherapy kills cancer -- but it kills the rest of your body, too. Instead of using human design to fight cancer, why not use nature's? In this quick talk, Wayne explains how her lab is creating nanoparticle treatments that bind to immune cells, your body's first responders, to precisely target cancer cells without damaging healthy ones.
The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds a Lake Tahoe-sized volume of water from the summer melt. Does this water stay there, or does it find its way out to the ocean and contribute to global sea level rise? Join glaciologist Kristin Poinar for a trip to this frozen, forgotten land to find out.

In conversation with TED Curator Chris Anderson, Amanpour discusses fake news, objectivity in journalism, the leadership vacuum in global politics and more, sharing her wisdom along the way. "Be careful where you get information from," she says. "Unless we are all engaged as global citizens who appreciate the truth, who understand science, empirical evidence and facts, then we are going to be wandering around -- to a potential catastrophe."
Artist Eric Dyer spent years working at a computer to produce images for the screen. Longing to get his hands back on his work, he began exploring the zoetrope, a popular 19th-century device that was used to create the illusion of motion long before the arrival of film. In this vibrant talk, he showcases his resulting art inventions: spinning sculptures and that evoke beautiful, dreamlike scenes. (Warning: This talk includes flashing images and lights. Those who are photosensitive or have seizures trigged by strobes are advised to avoid.)
Sara Menker quit a career in commodities trading to figure out how the global value chain of agriculture works. Her discoveries have led to some startling predictions: "We could have a tipping point in global food and agriculture if surging demand surpasses the agricultural system's structural capacity to produce food," she says. "People could starve and governments may fall." Menker's models predict that this scenario could happen in a decade -- that the world could be short 214 trillion calories per year by 2027. She offers a vision of this impossible world as well as some steps we can take today to avoid it.

"Start asking people what problems they're inspired to solve and what talents they want to bring to work," Lee says. "When you invite people to be more, they can amaze us with how much more they can be."
We check our phones upwards of 50 times per day -- but when our kids play around with them, we get nervous. Are screens ruining childhood? Not according to children's media expert Sara DeWitt.
