Recommended TED “Ideas Worth Spreading” talks
- How to fight desertification and reverse climate change.
Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk. And it’s happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.
- Every city needs healthy honey bees.
Bees have been rapidly and mysteriously disappearing from rural areas, with grave implications for agriculture. But bees seem to flourish in urban environments — and cities need their help, too. Noah Wilson-Rich suggests that urban beekeeping might play a role in revitalizing both a city and a species.
- How we can eat our landscapes.
What should a community do with its unused land? Plant food, of course. With energy and humor, Pam Warhurst tells at the TEDSalon the story of how she, and a growing team of volunteers, came together to turn plots of unused land into communal vegetable gardens, and to change the narrative of food in their community.
- A teacher growing green in the South Bronx.
A whirlwind of energy and ideas, Stephen Ritz is a teacher in New York’s tough South Bronx, where he and his kids grow lush gardens for food, greenery — and jobs. Just try to keep up with this New York treasure as he spins through the many, many ways there are to grow hope in a neighborhood many have written off, or in your own.
- A guerilla gardener in South Central LA.
Ron Finley plants vegetable gardens in South Central LA — in abandoned lots, traffic medians, along the curbs. Why? For fun, for defiance, for beauty and to offer some alternative to fast food in a community where “the drive-thrus are killing more people than the drive-bys.
- A plant’s-eye view.
What if human consciousness isn’t the end-all and be-all of Darwinism? What if we are all just pawns in corn’s clever strategy game to rule the Earth? Author Michael Pollan asks us to see the world from a plant’s-eye view.
- One seed at a time, protecting the future of food .
The varieties of wheat, corn and rice we grow today may not thrive in a future threatened by climate change. Cary Fowler takes us inside a vast global seed bank, buried within a frozen mountain in Norway, that stores a diverse group of food-crop for whatever tomorrow may bring.
- Why we’re storing billions of seeds.
In this brief talk from TED U 2009, Jonathan Drori encourages us to save biodiversity — one seed at a time. Reminding us that plants support human life, he shares the vision of the Millennium Seed Bank, which has stored over 3 billion seeds to date from dwindling yet essential plant species.
- The beautiful tricks of flowers.
In this visually dazzling talk, Jonathan Drori shows the extraordinary ways flowering plants — over a quarter million species — have evolved to attract insects to spread their pollen: growing ‘landing-strips’ to guide the insects in, shining in ultraviolet, building elaborate traps, and even mimicking other insects in heat.
- A plea for bees.
Bees are dying in droves. Why? Leading apiarist Dennis vanEngelsdorp looks at the gentle, misunderstood creature’s important place in nature and the mystery behind its alarming disappearance.
- The hidden beauty of pollination.
Pollination: it’s vital to life on Earth, but largely unseen by the human eye. Filmmaker Louie Schwartzberg shows us the intricate world of pollen and pollinators with gorgeous high-speed images from his film “Wings of Life,” inspired by the vanishing of one of nature’s primary pollinators, the honeybee.
- Tristram Stuart – The global Food Waste Scandal.
Western countries throw out nearly half of their food, not because it’s inedible — but because it doesn’t look appealing. Tristram Stuart delves into the shocking data of wasted food, calling for a more responsible use of global resources.
- What’s wrong with our food system.
11-year-old Birke Baehr presents his take on a major source of our food — far-away and less-than-picturesque industrial farms. Keeping farms out of sight promotes a rosy, unreal picture of big-box agriculture, he argues, as he outlines the case to green and localize food production.
