Jane Goodall Talks To John Seigenthaler

She's best known for her pioneering work with chimpanzees, but Goodall is also a keen conservationist


John Seigenthaler: Your latest project is a book about plants. Can you draw the line for us between plants and chimpanzees?
Jane Goodall: Without plants, none of us would be here, chimpanzees, people or anything else, because everything either lives on plant food or lives on creatures that live on plant food.

One of the things you also discuss in this book is the challenges facing forests around the world. What do you think are the biggest challenges?
Human greed and human need. I mean, on the one hand, you've got desperately poor people, and they've got to try and feed their family. They don't have money to buy food, so they're cutting down trees to grow crops or to make charcoal so that they can get a bit of money and buy a bit of food. Then on the other hand, you've got the big timber companies coming in, some of them still clear-cutting and paying lots of money for a forest concession to the government. Then the people living in the forest suffer, as well as everything else.

In fact, in your book — I just want to read a couple of lines that you write — you say, "The truth is that when corporate greed and public demand for a better and better lifestyle are pitted against the health of the environment and the health of people, for that matter, it is the bottom line that wins …" You sound like an environmental activist, an angry environmental activist here.
Well, I do get angry when I think of the unsustainable lifestyle of so many about this materialistic, Western-based culture. How many of us have so much more than we need? I mean, we need money to live, and what goes wrong is when we live for money. That's happening more and more often. And as a result, I think, it's a very empty kind of society, and people, when you live and money is your goal and your god, then I think people lose a lot of sensitivity and human values and love and compassion.

You have great hope for nature, and hope is a theme through much of your writing. I was touched by the stories at the end of the book that talk about a couple of trees — Survivor, in particular. Could you tell that story?
Yes, Survivor is very dear to me because I was in New York at 9/11, and they found the one piece of tree that was still alive out of all the trees that were around those Twin Towers. It looked like a dead stump, blackened with fire and everything. But some people took it and nurtured it. This tree now is back at Ground Zero, and it's a beautiful pear. I've seen it in blossom. But that tree somehow epitomizes the resilience of nature and the passion of people because so many people said, "Oh, throw it away. You'll never get this tree to grow." But they didn't give up.
I do get angry when I think of the unsustainable lifestyle of so many about this materialistic, Western-based culture. How many of us have so much more than we need?


It was also damaged by a storm, wasn't it?
Yes, it had just begun to recover, and I think it was Hurricane Sandy that tore it down, and they rushed out and desperately propped it up. It's had a very dramatic life.

You speak of another tree, a cherry tree at Fukushima, another example of a tree surviving. But, you know, in that example, I really wonder about our world and where we're headed and whether or not there is hope when you see a disaster like that. Fukushima?
Fukushima. Yes. As I said, it's a hope based on the fact that we can do it, but in order to change the world and make it start moving in a better direction — instead of heading downhill, just start leveling it off, and then eventually coming up. We have to change attitudes. That's the thing. When people lose hope, as many people do — because many biologists point out that there isn't any hope — if everybody loses hope, what happens? You fall into apathy. There's no point doing anything. It doesn't matter. But how can we be bringing our children into a world and telling them there's no hope? That's cruel.

There's a saying about inheriting the earth from our parents. But you say in some ways, we've stolen …
We have. We have stolen their future. I began the youth program because I met so many young people who had lost hope, who said, "Well, you compromised our future, and there's nothing we can do about it." We have, but there is something we can do about it. At least I shall die fighting for that.

What's the most interesting thing you've learned about chimpanzees over the years?
How like us they are or how like them we are. I think the most shocking but very fascinating thing is when I realized that, like us, they have a dark side. That made them sadly seem more like us than I had thought before. But they are capable of violence, brutality and a kind of primitive war.


Can you take me back to the beginning? You were a secretary for anthropologist Louis Leakey. That's where you got your start, right?
That's where I got my start.

How did that happen?
When I was a tiny little girl, I wanted to go and study animals in Africa because I fell in love with Tarzan. And silly man married the wrong Jane, didn't he? But anyway, I was very jealous of her. But I decided I wanted to go to Africa and live with animals and write books about them. Everybody laughed except my amazing mother, who just said, "Well, if you really want something, you'll just have to work hard and take advantage of opportunity, and you'll get there in the end." I got invited by school friends, saved up my money working as a waitress, got out to Africa, heard about Louis Leakey, went to see him at the museum. I wasn't asking for a job. But he took me around. He asked me hundreds of questions, and because I had gone on learning about Africa and animals and spent hours in the Natural History Museum in London, I could answer many of his questions, and he just offered me a job as his secretary.

When was your first attempt to observe the chimpanzees?
It was 1960 he finally got the money for me to go, and the biggest problem to start with was that they all ran away. You know, they're very conservative. Never seen a white ape before. So they ran away. But eventually one of them, whom I named David Greybeard, with his nice, white beard, began to lose his fear, and that really opened a door for me.

How did you gain their trust?
Patience, wearing the same colored clothes all the time, pretending I wasn't interested in them.

How did your family see the work that you did? What did they have to say about it when you first started going into the jungle and hanging out with chimps?
My mother came. I wasn't allowed to be alone by the British authorities. It was Tanganyika then. And they said, "No, no, no," and they said, "Oh, but she must come with a companion." So my amazing mother volunteered for four months. I mean, how many mothers would? You know, we had this old, secondhand army tent, no sewn-in ground sheet — so, piece of canvas on the ground, roll up the sides to let in the air, and you let in the spiders and the snakes and the scorpions as well, which I didn't mind, but poor Mum.

You just turned 80 years old.
People are making a big deal of it, but, you know, well ...

Well, in some ways, you're a timeless figure in the study of nature and chimpanzees. Tell me what your life is like now at 80.
Well, it's ridiculous, really, because it's literally going from one continent to another. It's airplanes and hotels and interviews and lectures.

You said you're on the road some 300 days a year.
Yes. It's absurd, isn't it?

And you like it?
I hate the travel.

You do?
I hate it. Who could like going through airports today? I mean, it's really horrible. Then of course it's a carbon footprint, all this flying, but nobody's given me a magic carpet yet. And we do have, I would say, millions of young people planting trees now, so I hope it makes up.
Who could like going through airports today? I mean, it’s really horrible. Then of course it’s a carbon footprint, all this flying, but nobody’s given me a magic carpet yet.

Well, you've started this organization called Roots & Shoots. Tell us about it.
It began with 12 high school students, and it was about, actually, empowering young people to roll up their sleeves and make a difference. So once they understand the problems, they get to choose. We don't tell them what to do. But between them, they must choose a project to help people, a project to help animals, a project to help the environment. And woven in it is, "Let's learn to live in peace and harmony between religions and cultures." We have so far to go between us and the natural world.

You've spent your life protecting animals, but recently you've been involved in trying to help save elephants. Can you talk a little bit about that effort?
The poaching of elephants and rhinos and some other animals, too, have increased so dramatically. And it's become such a money earner. So you get criminal cartels coming in, and the money from slaughtering elephants and selling the ivory is actually supporting some of these terrorist groups. And of course it's the demand in Asia. And so we're using our Roots & Shoots groups in China — I would say we're using them because they want to do it. The slogan is, "If the buying stops, the killing stops." And a lot of the Chinese honestly believe that elephants shed their tusks, like deer. So they don't understand the horrible slaughter and suffering of individual animals, whether it's elephants, rhino, tigers, apes being shot for bush meat. You know, the slaughter is going on, and it's going on very fast. But once people understand and get a feeling for these animals, then they're more prepared to go out and do something about it.

You've also fought to protect animals from experimentation for medicine. Where does that stand today?
I first began talking to NIH [the National Institutes of Health] in 1986, and just last year the new director, Francis Collins, had — well, actually three years ago he had a committee put together to investigate what tests were being done on the over 300 NIH chimpanzees, and found none of them, nothing, was beneficial to humans. So he said, "Fine, they can go into sanctuary, into retirement." We have to raise the money now to get them all — but a lot of them are already in Chimp Haven Sanctuary. More and more chimps are coming out of medical research. There's very few left.

What do you think of zoos?
Zoos and zoos and zoos. Some zoos shouldn't be. The change in zoos over my life has been just incredible. Yes, there's an idea that wild animals and freedom — it's the best thing, but in so many cases they're under threat, their habitats being destroyed. There's hunters out there. Then you look at a group in a really good zoo, which has the right kind of environment. Then you think, "Well, let me be a chimp. Where would I rather be?" In the really well-protected places, obviously you want wild animals.

How has technology changed the study of animals and plants over your life?
It's completely changed. I started with a notebook and a pencil and a pair of secondhand binoculars, which was all we could afford. Now, we have a GIS, GPS satellite imagery mapping, and we have ways of measuring stress levels by collecting fecal samples. We hope to do a lot of conservation with working with Google Earth, Esri, DigitalGlobe, and getting software that enable us to, you know, get much more accurate pictures of where the trees are. But the most key thing is that we've actually trained the local people to use these Android tablets. So they're restoring the forest now, letting it regenerate. It's because in early '91, I flew over the whole area around Gombe, and I was so shocked because I knew there was deforestation — I hadn't realized it was total. It was pretty clear that we can't even try and save the chimps if the people are just struggling to survive because they're going to come into this last, lush, tiny island forest. We began improving their lives. As a result, they're now our partners in protecting the chimp habitat, but also restoring the habitat around their own villages. All those bales are now sprinkled with green, and the chimps have three times more forest than they had 10 years ago.

I think some people might be surprised to learn that the chimpanzee is not your favorite animal. Is that right?
Well, I just love dogs. I mean, I just love dogs. You know, when I got to Cambridge and was told I shouldn't have given the chimps names, they should have been numbered, and, you know, I couldn't talk about them having a personality, mind or emotion, I knew from the childhood teacher, my dog Rusty, that that couldn't be true. Animals — of course they have personality. Of course they can feel happy and sad and afraid, just like us.

Clearly, at 80 years old, you have no intention of slowing down.
Well, I suppose my body will slow me down at some point, but, you know, I'm lucky, and I got my father's genes. In fact, all my family lived long. So as long as I can, I shall go on doing this.

Big Brains. Small Films. Benoît Mandelbrot, The Father of Fractals


IBM celebrates the life of Benoît B. Mandelbrot, IBM Fellow Emeritus and Fractal Pioneer. In this final interview shot by filmmaker Errol Morris, Mandelbrot shares his love for mathematics and how it led him to his wondrous discovery of fractals. His work lives on today in many innovations in science, design, telecommunications, medicine, renewable energy, film (special effects), gaming (computer graphics) and more.

"People want to see patterns in the world. It is how we evolved. We descended from those primates who were best at spotting the telltale pattern of a predator in the forest, or of food in the savannah. So important is this skill that we apply it everywhere, warranted or not."

¿Por qué las nutrias marinas se ven cada vez más amenazadas?

Original: BigThink
Daniel Honan el 18 de febrero de 2012,

 

Ha habido un repunte alarmante de los ataques mortales de tiburones a las nutrias de mar por los tiburones de la costa central de California, y nadie parece saber por qué. Si bien los ataques de tiburones, en su mayoría blancos grandes - representaron aproximadamente el 10 por ciento de muertes de nutria marina en la década de 1990, en la actualidad esa cifra es del 30 por ciento.

Los investigadores han basado estas cifras sobre el número de nutrias marinas muertas que llegan a tierra con las mordeduras de tiburones. Las nutrias de mar están en la lista federal de especies en peligro, y los tiburones no están haciendo que la lucha contra la extinción de ellas sea más fácil.

¿Porqué los tiburones están cambiando sus hábitos de caza o se ha producido un cambio en la población de tiburones? La respuesta hasta ahora ha escapado a los científicos. Pero una cosa es segura: mantener una población estable de ambos tiburones y nutrias de mar es importante para nuestro medio ambiente humano. Como la oceanógrafa Sylvia Earle dijo a Big Think, si los tiburones están en peligro que significa que el océano está en problemas. Y eso significa que todos estamos en problemas.

Sylvia Earle ha estado en la frontera de la exploración del océano profundo por cuatro décadas. Ha dirigido más de 50 expediciones submarinas, y ella ha sido una defensora incansable por igual para nuestros océanos y las criaturas que viven en ellas.

Andrés Hurtado García - Periodista, Fotógrafo, Ecólogo. Protector de la Naturaleza Colombiana



Andrés Hurtado García (1941) es un periodista y ecologista colombiano oriundo de la ciudad de Armenia, Colombia. Pertenece a la comunidad de los Hermanos Maristas. Doctor en literatura y reconocido fotógrafo de naturaleza, ha ganado varios premios nacionales e internacionales de periodismo y medio ambiente, incluido el Premio Nacional de Periodismo Simón Bolívar. Tiene una columna quincenal en el diario El Tiempo y es escritor de varias revistas nacionales y del exterior relacionadas con el medio ambiente. Aunque menos conocidos, son también de destacar sus artículos literarios en revistas y textos académicos. Andrés Hurtado García pertenece a la Comunidad de Hermanos Maristas, cuya inspiración se basa en el francés San Marcelino Champagnat (1789-1840) fundador de la Comunidad.

Es un periodista independiente, amante de la naturaleza, que desde hace casi cincuenta años promueve la preservación del medio ambiente bajo la premisa de conocer para amar y amar para preservar. Sin duda alguna es él quien mejor conoce la geografía colombiana en virtud a sus frecuentes travesías por la mayoría de los parajes colombianos, desde las costas hasta las cumbres nevadas sin dejar de lado la selva y los llanos. Fruto de ello, su archivo fotográfico de más de tres millones de fotografías esta considerado como uno de los mejores en esta materia. Además se desempeña como profesor en el Colegio Champagnat de Bogotá, donde desde hace unos años, estableció salidas ecológicas para mejorar los conociemientos de los estudiantes. Es uno de los pioneros del ecoturismo en Colombia y también uno de los primeros impulsores del montañismo colombiano. Como asesor y profesor de escalada de la Escuela Nacional de Alta Montaña de Madrid, España, Andrés Hurtado fue el primer colombiano en hacer parte de una expedición al Himalaya en 1972. Actualmente es director de la Semana de la Montaña, ciclo anual de conferencias y exposiciones de montaña y vida al aire libre que se realiza en Bogotá y que en el 2009 llega a su XII versión.

Benoit Mandlebrot, quien dió vida a los fractales hoy parte en un nuevo viaje a sus 85 años

Father of fractals Mandelbrot dies at 85

By Clive Cookson
Published: October 17 2010 19:12 | Last updated: October 17 2010 19:12
Benoît Mandelbrot, one of the most original and influential mathematicians of the 20th century, has died of pancreatic cancer at the age of 85. He was the father of fractal geometry – finding underlying patterns in roughness and irregularity – and was a key figure in the broader field of chaos theory.
Mandelbrot had enormously wide interests. Over a 60-year career, working first in France and then the US, he applied his findings to physics, biology and economics, publishing devastating critiques of modern mathematical finance.
His most famous creation is the “Mandelbrot set”, a mathematical creation of infinite complexity. The patterns created have brought mathematics into popular culture and fractals have become a standard feature of school curriculums.
His family said Mandelbrot saw himself as a scientific “maverick”, “moving across many disciplines at once to find new insights, and seeking always a measure of order in physical, mathematical or social phenomena that are characterised by abundant data but wild variability”.
Benoît Mandelbrot was born in Warsaw on November 20 1924 but moved as a child with his Jewish family to France, where he survived the second world war and began his mathematical career with the Centre National de la Recherche Scientifique in Paris.
Nicolas Sarkozy, the French president, said Mandelbrot’s was “a powerful, original mind that never shied away from innovation and battering preconceived ideas”.
“France is proud to have received Benoît Mandelbrot and to have allowed him to benefit from the best education,” said Mr Sarkozy.
In 1958 Mandelbrot emigrated to the US, where he spent most of his professional life working for IBM at its main research centre at Yorktown Heights, New York. Although his work there was valuable for IBM, for example on the suppression of electronic “noise” in computing and telecommunications, the company also gave him considerable time and freedom to develop his interests and take part-time academic fellowships.
Towards the end of his career, after leaving IBM, Mandelbrot taught mathematics at Yale University. He finally accepted a tenured academic job in 1999 at Yale as Sterling Professor of Mathematical Sciences: at the age of 75, he was one of the oldest people ever to begin his first full-time professorship.
Mandelbrot published several books, of which the most celebrated was The Fractal Geometry of Nature in 1982. While he had studied markets throughout his career, starting with a 1962 paper on cotton prices, financial mathematics became a pressing interest during the last decade of his life. In 2004 he published with Richard Hudson The (Mis)Behaviour of Markets: A Fractal View of Risk, Ruin and Reward – a devastating attack on the failure of mainstream economists and mathematicians to understand the likelihood of wild swings in prices and the risk of financial disaster.
Mandelbrot felt vindicated by subsequent events, such as the near collapse of the global banking system in 2008.
Mr Hudson, publisher of the Science Business media group, described his co-author as “the ultimate interdisciplinary scientist. The scientific world is built in silos, and he made a career out of going into other people’s silos uninvited and coming up with insights they did not have. In economics he was an outsider – and often not a welcome one”.
Mandelbrot is survived by his wife Aliette, sons Laurent and Didier, both medical doctors, and three grandchildren.
