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.
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.
