🔴Nature is everywhere we just need to learn to see it We are stealing nature from our children. Now, when I say this, I don't mean that we are destroying nature that they will have wanted us to preserve, although that is unfortunately also the case. What I mean here is that we've started to define nature in a way that's so purist and so strict that under the definition we're creating for ourselves, there won't be any nature left for our children when they're adults. But there's a fix for this. So let me explain. Right now, humans use half of the world to live, to grow their crops and their timber, to pasture their animals. If you added up all the human beings, we would weigh 10 times as much as all the wild mammals put together. We cut roads through the forest. We have added little plastic particles to the sand on ocean beaches. We've changed the chemistry of the soil with our artificial fertilizers. And of course, we've changed the chemistry of the air. So when you take your next breath, you'll be breathing in 42 percent more carbon dioxide than if you were breathing in 1750. So all of these changes, and many others, have come to be kind of lumped together under this rubric of the "Anthropocene." And this is a term that some geologists are suggesting we should give to our current epoch, given how pervasive human influence has been over it. Now, it's still just a proposed epoch, but I think it's a helpful way to think about the magnitude of human influence on the planet. So where does this put nature? What counts as nature in a world where everything is influenced by humans? So 25 years ago, environmental writer Bill McKibben said that because nature was a thing apart from man and because climate change meant that every centimeter of the Earth was altered by man, then nature was over. In fact, he called his book "The End of Nature." I disagree with this. I just disagree with this. I disagree with this definition of nature, because, fundamentally, we are animals. Right? Like, we evolved on this planet in the context of all the other animals with which we share a planet, and all the other plants, and all the other microbes. And so I think that nature is not that which is untouched by humanity, man or woman. I think that nature is anywhere where life thrives, anywhere where there are multiple species together, anywhere that's green and blue and thriving and filled with life and growing. And under that definition, things look a little bit different. Now, I understand that there are certain parts of this nature that speak to us in a special way. Places like Yellowstone, or the Mongolian steppe, or the Great Barrier Reef or the Serengeti. Places that we think of as kind of Edenic representations of a nature before we screwed everything up. And in a way, they are less impacted by our day to day activities. Many of these places have no roads or few roads, so on, like such. But ultimately, even these Edens are deeply influenced by humans. Now, let's just take North America, for example, since that's where we're meeting. So between about 15,000 years ago when people first came here, they started a process of interacting with the nature that led to the extinction of a big slew of large-bodied animals, from the mastodon to the giant ground sloth, saber-toothed cats, all of these cool animals that unfortunately are no longer with us. And when those animals went extinct, you know, the ecosystems didn't stand still. Massive ripple effects changed grasslands into forests, changed the composition of forest from one tree to another. So even in these Edens, even in these perfect-looking places that seem to remind us of a past before humans, we're essentially looking at a humanized landscape. Not just these prehistoric humans, but historical humans, indigenous people all the way up until the moment when the first colonizers showed up. And the case is the same for the other continents as well. Humans have just been involved in nature in a very influential way for a very long time. Now, just recently, someone told me,

People with certain mood disorders and PTSD often have difficulty sleeping, leading some scientists to believe that lack of dreaming may be a contributing factor to their illnesses. We dream to solve problems. Unconstrained by reality and the rules of conventional logic, in your dreams, your mind can create limitless scenarios to help you grasp problems and formulate solutions that you may not consider while awake. John Steinbeck called it the committee of sleep, and research has demonstrated the effectiveness of dreaming on problem solving. It's also how renowned chemist August Kekule discovered the structure of the benzene molecule, and it's the reason that sometimes the best solution for a problem is to sleep on it. And those are just a few of the more prominent theories. As technology increases our capability for understanding the brain, it's possible that one day we will discover the definitive reason for them. But until that time arrives, we'll just have to keep on dreaming. #Consciousness #History #Personality #Philosophy #Psychology #Brain #Sleep #Education #TED_Ed #Animation 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

🔴Why Do We Dream? In the third millenium BCE, Mesopotamian kings recorded and interpreted their dreams on wax tablets. A thousand years later, Ancient Egyptians wrote a dream book listing over a hundred common dreams and their meanings. And in the years since, we haven't paused in our quest to understand why we dream. So, after a great deal of scientific research, technological advancement, and persistence, we still don't have any definite answers, but we have some interesting theories. We dream to fulfill our wishes. In the early 1900s, Sigmund Freud proposed that while all of our dreams, including our nightmares, are a collection of images from our daily conscious lives, they also have symbolic meanings, which relate to the fulfillment of our subconscious wishes. Freud theorized that everything we remember when we wake up from a dream is a symbolic representation of our unconscious primitive thoughts, urges, and desires. Freud believed that by analyzing those remembered elements, the unconscious content would be revealed to our conscious mind, and psychological issues stemming from its repression could be addressed and resolved. We dream to remember. To increase performance on certain mental tasks, sleep is good, but dreaming while sleeping is better. In 2010, researchers found that subjects were much better at getting through a complex 3-D maze if they had napped and dreamed of the maze prior to their second attempt. In fact, they were up to ten times better at it than those who only thought of the maze while awake between attempts, and those who napped but did not dream about the maze. Researchers theorize that certain memory processes can happen only when we are asleep, and our dreams are a signal that these processes are taking place. We dream to forget. There are about 10,000 trillion neural connections within the architecture of your brain. They are created by everything you think and everything you do. A 1983 neurobiological theory of dreaming, called reverse learning, holds that while sleeping, and mainly during REM sleep cycles, your neocortex reviews these neural connections and dumps the unnecessary ones. Without this unlearning process, which results in your dreams, your brain could be overrun by useless connections and parasitic thoughts could disrupt the necessary thinking you need to do while you're awake. We dream to keep our brains working. The continual activation theory proposes that your dreams result from your brain's need to constantly consolidate and create long-term memories in order to function properly. So when external input falls below a certain level, like when you're asleep, your brain automatically triggers the generation of data from its memory storages, which appear to you in the form of the thoughts and feelings you experience in your dreams. In other words, your dreams might be a random screen saver your brain turns on so it doesn't completely shut down. We dream to rehearse. Dreams involving dangerous and threatening situations are very common, and the primitive instinct rehearsal theory holds that the content of a dream is significant to its purpose. Whether it's an anxiety-filled night of being chased through the woods by a bear or fighting off a ninja in a dark alley, these dreams allow you to practice your fight or flight instincts and keep them sharp and dependable in case you'll need them in real life. But it doesn't always have to be unpleasant. For instance, dreams about your attractive neighbor could actually give your reproductive instinct some practice, too. We dream to heal. Stress neurotransmitters in the brain are much less active during the REM stage of sleep, even during dreams of traumatic experiences, leading some researchers to theorize that one purpose of dreaming is to take the edge off painful experiences to allow for psychological healing. Reviewing traumatic events in your dreams with less mental stress may grant you a clearer perspective and enhanced ability to process them in psychologically healthy ways.

So it was a hard lesson that he didn't like me, but you know what, he was right. I was a middle-class kid living in a poor country. I had a bike, and he barely had food. Sometimes, it's the messages that we don't want to hear, the ones that make us want to crawl out of ourselves, that we need to hear the most. For every lovable storyteller who steals your heart, there are hundreds more whose voices are slurred and ragged, who don't get to stand up on a stage dressed in fine clothes like this. There are a million angry-boy-on-a-bike stories and we can't afford to ignore them simply because we don't like their protagonists or because that's not the kid that we would bring home with us from the orphanage. The third reason that I think that stories don't necessarily make the world a better place is that too often we are so invested in the personal narrative that we forget to look at the bigger picture. And so we applaud someone when they tell us about their feelings of shame, but we don't necessarily link that to oppression. We nod understandingly when someone says they felt small, but we don't link that to discrimination. The most important stories, especially for social justice, are those that do both, that are both personal and allow us to explore and understand the political. But it's not just about the stories we like versus the stories we choose to ignore. Increasingly, we are living in a society where there are larger forces at play, where stories are actually for many people beginning to replace the news. Yeah? We live in a time where we are witnessing the decline of facts, when emotions rule and analysis, it's kind of boring, right? Where we value what we feel more than what we actually know. A recent report by the Pew Center on trends in America indicates that only 10 percent of young adults under the age of 30 "place a lot of trust in the media." Now, this is significant. It means that storytellers are gaining trust at precisely the same moment that many in the media are losing the confidence in the public. This is not a good thing, because while stories are important and they help us to have insights in many ways, we need the media. From my years as a social justice activist, I know very well that we need credible facts from media institutions combined with the powerful voices of storytellers. That's what pushes the needle forward in terms of social justice. In the final analysis, of course, it is justice that makes the world a better place, not stories. Right? And so if it is justice that we are after, then I think we mustn't focus on the media or on storytellers. We must focus on audiences, on anyone who has ever turned on a radio or listened to a podcast, and that means all of us. So a few concluding thoughts on what audiences can do to make the world a better place. So firstly, the world would be a better place, I think, if audiences were more curious and more skeptical and asked more questions about the social context that created those stories that they love so much. Secondly, the world would be a better place if audiences recognized that storytelling is intellectual work. And I think it would be important for audiences to demand more buttons on their favorite websites, buttons for example that say, "If you liked this story, click here to support a cause your storyteller believes in." Or "click here to contribute to your storyteller's next big idea." Often, we are committed to the platforms, but not necessarily to the storytellers themselves. And then lastly, I think that audiences can make the world a better place by switching off their phones, by stepping away from their screens and stepping out into the real world beyond what feels safe. Alice Walker has said, "Look closely at the present you are constructing. It should look like the future you are dreaming." Storytellers can help us to dream, but it's up to all of us to have a plan for justice. #Activism #Africa #Communication #Collaboration #Community #Empathy #Humanity #Journalism 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

I'm not so sure, and I actually work for a place called the Centre for Stories. And my job is to help to tell stories that challenge mainstream narratives about what it means to be black or a Muslim or a refugee or any of those other categories that we talk about all the time. But I come to this work after a long history as a social justice activist, and so I'm really interested in the ways that people talk about nonfiction storytelling as though it's about more than entertainment, as though it's about being a catalyst for social action. It's not uncommon to hear people say that stories make the world a better place. Increasingly, though, I worry that even the most poignant stories, particularly the stories about people who no one seems to care about, can often get in the way of action towards social justice. Now, this is not because storytellers mean any harm. Quite the contrary. Storytellers are often do-gooders like me and, I suspect, yourselves. And the audiences of storytellers are often deeply compassionate and empathetic people. Still, good intentions can have unintended consequences, and so I want to propose that stories are not as magical as they seem. So three — because it's always got to be three — three reasons why I think that stories don't necessarily make the world a better place. Firstly, stories can create an illusion of solidarity. There is nothing like that feel-good factor you get from listening to a fantastic story where you feel like you climbed that mountain, right, or that you befriended that death row inmate. But you didn't. You haven't done anything. Listening is an important but insufficient step towards social action. Secondly, I think often we are drawn towards characters and protagonists who are likable and human. And this makes sense, of course, right? Because if you like someone, then you care about them. But the inverse is also true. If you don't like someone, then you don't care about them. And if you don't care about them, you don't have to see yourself as having a moral obligation to think about the circumstances that shaped their lives. I learned this lesson when I was 14 years old. I learned that actually, you don't have to like someone to recognize their wisdom, and you certainly don't have to like someone to take a stand by their side. So my bike was stolen while I was riding it — which is possible if you're riding slowly enough, which I was. So one minute I'm cutting across this field in the Nairobi neighborhood where I grew up, and it's like a very bumpy path, and so when you're riding a bike, you don't want to be like, you know — And so I'm going like this, slowly pedaling, and all of a sudden, I'm on the floor. I'm on the ground, and I look up, and there's this kid peddling away in the getaway vehicle, which is my bike, and he's about 11 or 12 years old, and I'm on the floor, and I'm crying because I saved a lot of money for that bike, and I'm crying and I stand up and I start screaming. Instinct steps in, and I start screaming, "Mwizi, mwizi!" which means "thief" in Swahili. And out of the woodworks, all of these people come out and they start to give chase. This is Africa, so mob justice in action. Right? And I round the corner, and they've captured him, they've caught him. The suspect has been apprehended, and they make him give me my bike back, and they also make him apologize. Again, you know, typical African justice, right? And so they make him say sorry. And so we stand there facing each other, and he looks at me, and he says sorry, but he looks at me with this unbridled fury. He is very, very angry. And it is the first time that I have been confronted with someone who doesn't like me simply because of what I represent. He looks at me with this look as if to say, "You, with your shiny skin and your bike, you're angry at me?"

🔴If a story moves you, act on it So earlier this year, I was informed that I would be doing a TED Talk. So I was excited, then I panicked, then I was excited, then I panicked, and in between the excitement and the panicking, I started to do my research, and my research primarily consisted of Googling how to give a great TED Talk. And interspersed with that, I was Googling Chimamanda Ngozi Adichie. How many of you know who that is? So I was Googling her because I always Google her because I'm just a fan, but also because she always has important and interesting things to say. And the combination of those searches kept leading me to her talk on the dangers of a single story, on what happens when we have a solitary lens through which to understand certain groups of people, and it is the perfect talk. It's the talk that I would have given if I had been famous first. You know, and you know, like, she's African and I'm African, and she's a feminist and I'm a feminist, and she's a storyteller and I'm a storyteller, so I really felt like it's my talk. So I decided that I was going to learn how to code, and then I was going to hack the internet and I would take down all the copies of that talk that existed, and then I would memorize it, and then I would come here and deliver it as if it was my own speech. So that plan was going really well, except the coding part, and then one morning a few months ago, I woke up to the news that the wife of a certain presidential candidate had given a speech that — that sounded eerily like a speech given by one of my other faves, Michelle Obama. And so I decided that I should probably write my own TED Talk, and so that is what I am here to do. I'm here to talk about my own observations about storytelling. I want to talk to you about the power of stories, of course, but I also want to talk about their limitations, particularly for those of us who are interested in social justice. So since Adichie gave that talk seven years ago, there has been a boom in storytelling. Stories are everywhere, and if there was a danger in the telling of one tired old tale, then I think there has got to be lots to celebrate about the flourishing of so many stories and so many voices. Stories are the antidote to bias. In fact, today, if you are middle class and connected via the internet, you can download stories at the touch of a button or the swipe of a screen. You can listen to a podcast about what it's like to grow up Dalit in Kolkata. You can hear an indigenous man in Australia talk about the trials and triumphs of raising his children in dignity and in pride. Stories make us fall in love. They heal rifts and they bridge divides. Stories can even make it easier for us to talk about the deaths of people in our societies who don't matter, because they make us care. Right?

🔴Why The Octopus Brain Is So Extraordinary What could octopuses possibly have in common with us? After all, they don't have lungs, spines, or even a plural noun we can all agree on. But what they do have is the ability to solve puzzles, learn through observation, and even use tools, just like some other animals we know. And what makes octopus intelligence so amazing is that it comes from a biological structure completely different from ours. The 200 or so species of octopuses are mollusks belonging to the order cephalopoda, Greek for head-feet. Those heads contain impressively large brains, with a brain to body ratio similar to that of other intelligent animals, and a complex nervous system with about as many neurons as that of a dog. But instead of being centralized in the brain, these 500 million neurons are spread out in a network of interconnected ganglia organized into three basic structures. The central brain only contains about 10% of the neurons, while the two huge optic lobes contain about 30%. The other 60% are in the tentacles, which for humans would be like our arms having minds of their own. This is where things get even more interesting. Vertebrates like us have a rigid skeleton to support our bodies, with joints that allow us to move. But not all types of movement are allowed. You can't bend your knee backwards, or bend your forearm in the middle, for example. Cephalopods, on the other hand, have no bones at all, allowing them to bend their limbs at any point and in any direction. So shaping their tentacles into any one of the virtually limitless number of possible arrangements is unlike anything we are used to. Consider a simple task, like grabbing and eating an apple. The human brain contains a neurological map of our body. When you see the apple, your brain's motor center activates the appropriate muscles, allowing you to reach out with your arm, grab it with your hand, bend your elbow joint, and bring it to your mouth. For an octopus, the process is quite different. Rather than a body map, the cephalopod brain has a behavior library. So when an octopus sees food, its brain doesn't activate a specific body part, but rather a behavioral response to grab. As the signal travels through the network, the arm neurons pick up the message and jump into action to command the movement. As soon as the arm touches the food, a muscle activation wave travels all the way through the arm to its base, while the arm sends back another wave from the base to the tip. The signals meet halfway between the food and the base of the arm, letting it know to bend at that spot. What all this means is that each of an octopus's eight arms can essentially think for itself. This gives it amazing flexibility and creativity when facing a new situation or problem, whether its opening a bottle to reach food, escaping through a maze, moving around in a new environment, changing the texture and the color of its skin to blend into the scenery, or even mimicking other creatures to scare away enemies. Cephalopods may have evolved complex brains long before our vertebrate relatives. And octopus intelligence isn't just useful for octopuses. Their radically different nervous system and autonomously thinking appendages have inspired new research in developing flexible robots made of soft materials. And studying how intelligence can arise along such a divergent evolutionary path can help us understand more about intelligence and consciousness in general. Who knows what other forms of intelligent life are possible, or how they process the world around them. #Animals #Animation #TED_Ed #Brain #Biology #Evolution #Science #Ocean 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

Because, see, I'm afraid every day. I can't remember a time when I wasn't.

🔴Courage is contagious So, I'm afraid. Right now, on this stage, I feel fear. In my life, I ain't met many people that will readily admit when they are afraid. And I think that's because deep down, they know how easy it spreads. See, fear is like a disease. When it moves, it moves like wildfire. But what happens when, even in the face of that fear, you do what you've got to do? That's called courage. And just like fear, courage is contagious. See, I'm from East St. Louis, Illinois. That's a small city across the Mississippi River from St. Louis, Missouri. I have lived in and around St. Louis my entire life. When Michael Brown, Jr., an ordinary teenager, was gunned down by police in 2014 in Ferguson, Missouri -- another suburb, but north of St. Louis -- I remember thinking, he ain't the first, and he won't be the last young kid to lose his life to law enforcement. But see, his death was different. When Mike was killed, I remember the powers that be trying to use fear as a weapon. The police response to a community in mourning was to use force to impose fear: fear of militarized police, imprisonment, fines. The media even tried to make us afraid of each other by the way they spun the story. And all of these things have worked in the past. But like I said, this time it was different. Michael Brown's death and the subsequent treatment of the community led to a string of protests in and around Ferguson and St. Louis. When I got out to those protests about the fourth or fifth day, it was not out of courage; it was out of guilt. See, I'm black. I don't know if y'all noticed that. But I couldn't sit in St. Louis, minutes away from Ferguson, and not go see. So I got off my ass to go check it out. When I got out there, I found something surprising. I found anger; there was a lot of that. But what I found more of was love. People with love for themselves. Love for their community. And it was beautiful -- until the police showed up. Then a new emotion was interjected into the conversation: fear. Now, I'm not going to lie; when I saw those armored vehicles, and all that gear and all those guns and all those police I was terrified -- personally. And when I looked around that crowd, I saw a lot of people that had the same thing going on. But I also saw people with something else inside of them. That was courage. See, those people yelled, and they screamed, and they were not about to back down from the police. They were past that point. And then I could feel something in me changing, so I yelled and I screamed, and I noticed that everybody around me was doing the same thing. And there was nothing like that feeling. So I decided I wanted to do something more. I went home, I thought: I'm an artist. I make shit. So I started making things specific to the protest, things that would be weapons in a spiritual war, things that would give people voice and things that would fortify them for the road ahead. I did a project where I took pictures of the hands of protesters and put them up and down the boarded-up buildings and community shops. My goal was to raise awareness and to raise the morale. And I think, for a minute at least, it did just that. Then I thought, I want to uplift the stories of these people I was watching being courageous in the moment. And myself and my friend, and filmmaker and partner Sabaah Folayan did just that with our documentary, "Whose Streets?" I kind of became a conduit for all of this courage that was given to me. And I think that's part of our job as artists. I think we should be conveyors of courage in the work that we do. And I think that we are the wall between the normal folks and the people that use their power to spread fear and hate, especially in times like these. So I'm going to ask you. Y'all the movers and the shakers, you know, the thought leaders: What are you gonna do with the gifts that you've been given to break us from the fear the binds us every day?

A phone is much more than it appears to be on the surface. It’s an assemblage of elements from multiple countries, linked to impacts that are unfolding on a global scale. So, until someone invents a completely sustainable smartphone, we’ll need to come to terms with how this technology affects widespread places and people. #TED_Ed #Sustainability #Technology #Resources #Natural_Resources 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

🔴Whats A Smartphone Made Of? As of 2018, there are around 2.5 billion smartphone users in the world. If we broke open all their newest phones, which are just a fraction of the total that’ve been built, and split them into their component parts, that would produce around 85,000 kilograms of gold, 875,000 of silver, and 40 million kilograms of copper. How did this precious cache get into our phones, and can we reclaim it? Gold, silver, and copper are actually just a few of the 70 or so chemical elements that make up the average smartphone. These can be divided into different groups, two of the most critical being rare earth elements and precious metals. Rare earths are a selection of 17 elements that are actually common in Earth’s crust and are found in many areas across the world in low concentrations. These elements have a huge range of magnetic, phosphorescent, and conductive properties that make them crucial to modern technologies. In fact, of the 17 types of rare earth metals, phones and other electronics may contain up to 16. In smartphones, these create the screen and color display, aid conductivity, and produce the signature vibrations, amongst other things. And yet, crucial as they are, extracting these elements from the earth is linked to some disturbing environmental impacts. Rare earth elements can often be found, but in many areas, it’s not economically feasible to extract them due to low concentrations. Much of the time, extracting them requires a method called open pit mining that exposes vast areas of land. This form of mining destroys huge swaths of natural habitats, and causes air and water pollution, threatening the health of nearby communities. Another group of ingredients in smartphones comes with similar environmental risks: these are metals such as copper, silver, palladium, aluminum, platinum, tungsten, tin, lead, and gold. We also mine magnesium, lithium, silica, and potassium to make phones, and all of it is associated with vast habitat destruction, as well as air and water pollution. Mining comes with worrying social problems, too, like large-scale human and animal displacement to make way for industrial operations, and frequently, poor working conditions for laborers. Lastly, phone production also requires petroleum, one of the main drivers of climate change. That entwines our smartphones inextricably with this growing planetary conundrum. And, what’s more, the ingredients we mine to make our phones aren’t infinite. One day, they’ll simply run out, and we haven’t yet discovered effective replacements for some. Despite this, the number of smartphones is on a steady increase; by 2019 it’s predicted that there’ll be close to 3 billion in use. This means that reclaiming the bounty within our phones is swiftly becoming a necessity. So, if you have an old phone, you might want to consider your options before throwing it away. To minimize waste, you could donate it to a charity for reuse, take it to an e-waste recycling facility, or look for a company that refurbishes old models. However, even recycling companies need our scrutiny. Just as the production of smartphones comes with social and environmental problems, dismantling them does too. E-waste is sometimes intentionally exported to countries where labor is cheap but working conditions are poor. Vast workforces, often made up of women and children, may be underpaid, lack the training to safely disassemble phones, and be exposed to elements like lead and mercury, which can permanently damage their nervous systems. Phone waste can also end up in huge dump sites, leaching toxic chemicals into the soil and water, mirroring the problems of the mines where the elements originated.
