👁How to grow a forest in your backyard
‌
🗣Subtitle: Farsi | English | Turkish

👣Forests don't have to be far-flung nature reserves, isolated from human life. Instead, we can grow them right where we are -- even in cities. Eco-entrepreneur and TED Fellow Shubhendu Sharma grows ultra-dense, biodiverse mini-forests of native species in urban areas by engineering soil, microbes and biomass to kickstart natural growth processes. Follow along as he describes how to grow a 100-year-old forest in just 10 years, and learn how you can get in on this tiny jungle party.

👁How we can make crops survive without water
‌
🗣Subtitle: Farsi | English | Turkish

👣As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: \"resurrection plants\" -- super-resilient plants that seemingly come back from the dead. Could they hold promise for growing food in our coming hotter, drier world?

👁A simple solution to the coming phosphorus crisis
‌
🗣Subtitle: Farsi | English

👣There's a farming crisis no one is talking about: The world is running out of phosphorus, an essential element that's a key component of DNA and the basis of cellular communication. As biologist Mohamed Hijri shows, all roads of this crisis lead back to how we farm -- with chemical fertilizers chock-full of the element, which plants are not efficient at absorbing. One solution? A microscopic mushroom ...

👁How trees talk to each other
🗣Subtitle: Farsi | English | Turkish

👣\"A forest is much more than what you see,\" says ecologist Suzanne Simard. Her 30 years of research in Canadian forests have led to an astounding discovery -- trees talk, often and over vast distances. Learn more about the harmonious yet complicated social lives of trees and prepare to see the natural world with new eyes.

👁Ecology from the air
🗣Subtitle: Farsi | English | Turkish

👣What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls \"a very high-tech accounting system\" of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.

👁Why bees are disappearing
🗣Subtitle: Farsi | English | Turkish

👣Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world's crops. Could this incredible species be holding up a mirror for us?

👁Lessons from fungi on markets and economics
🗣Subtitle: Farsi | English

👣Resource inequality is one of our greatest challenges, but it's not unique to humans. Like us, mycorrhizal fungi that live in plant and tree roots strategically trade, steal and withhold resources, displaying remarkable parallels to humans in their capacity to be opportunistic (and sometimes ruthless) -- all in the absence of cognition. In a mind-blowing talk, evolutionary biologist Toby Kiers shares what fungi networks and relationships reveal about human economies, and what they can tell us about inequality.

👁Are indoor vertical farms the future of agriculture?
🗣Subtitle: Farsi | English | Turkish

👣By 2050, the global population is projected to reach 9.8 billion. How are we going to feed everyone? Investment-banker-turned-farmer Stuart Oda points to indoor vertical farming: growing food on tiered racks in a controlled, climate-proof environment. In a forward-looking talk, he explains how this method can maintain better safety standards, save money, use less water and help us provide for future generations.

👁How one tree grows 40 different kinds of fruit
🗣Subtitle: Farsi | English | Turkish

👣Artist Sam Van Aken shares the breathtaking work behind the \"Tree of 40 Fruit,\" an ongoing series of hybridized fruit trees that grow 40 different varieties of peaches, plums, apricots, nectarines and cherries -- all on the same tree. What began as an art project to showcase beautiful, multi-hued blossoms has become a living archive of rare heirloom specimens and their histories, a hands-on (and delicious!) way to teach people about cultivation and a vivid symbol of the need for biodiversity to ensure food security. \"More than just food, embedded in these fruit is our culture ... In many ways, these fruit are our story,\" Van Aken says.

👁Nature's fortress: How cacti keep water in and predators out
🧠Lucas C. Majure
🗣Subtitle: 🇹🇷Turkish | 🇬🇧English

👣If you were a jackrabbit in the desert, you'd be glad to stumble across a cactus: the flesh of these plants is a water source for many animals. Known for their spines and succulent stems, cacti of all shapes and sizes have evolved to not just survive, but thrive, in some of the harshest desert climates on Earth. So how do they do it? Lucas C. Majure shares the prickly plant's unique adaptations. [Directed by Joseph Clark, Oh Studio, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].
