If you care anything about what your food tastes like, if you've dug a fork into food, you really care about digging a fork into the Earth. And that's my whole connection to all of this. You care about not just the quality of food, but whether food is going to feed everybody on this planet, which is one of the main questions we have to answer these days-- enough food, enough nutritious food for everybody. When I was assigned to China as a reporter a few years ago, for me, the most heartbreaking thing I saw was in the countryside to see these dense concentrations of farmers who were asked to leave the land that they had farmed for generations and put in densely populated living conditions no longer close to their land because land was that precious. And the government wanted to develop it. And here, I saw people who knew the art of farming-- and it is indeed an art, growing food and growing it well-- who had been through chemical industrial farming who were told that some of the land that they farm was now too toxic, over-fertilized, and over-chemicalized for them to do any more, but who still in their genes and just one generation back knew how to grow food in mainly a sustainable way. And to me, I brought that home with me. And to me, it's the overriding question for this age and for all of us. So from the time I was an immigrant that arrived in this country, I'd heard about double digging. I'd heard about biointensive. And today, for me to meet John and realize that he is this complete visionary who isn't just a farmer, but is thinking about food for all of us and for the future of this planet is indeed an honor. So please welcome John. [APPLAUSE] JOHN JEAVONS: Thank you, Liv. Take the lights down on the screen. They got me lit. Before we begin, I'd like to make one reflection to set the tone. What Liz said about China in some way reminded me of it. In 1995, we had an intern come and train with us in Northern California for six months. And he shared with me that the cost of farmable soil in Monterey, Mexico, was $4 a pound. Do you realize that gasoline only costs $50 a pound currently at the pump? $50. Oh, there we go again. We're going to have to redo this one. Do you realize that in Monterey, Mexico, that farmable soil, if you go to purchase it, costs $4 a pound, where gasoline at the pumps today costs $0.50 a pound. So they have their priorities right. They realize the preciousness of the soil. And they realize that the soil is worth eight times gasoline. Wow. That's really hard to wrap our minds around, I think. Even for me, it is, and I've been working with this for 41 years. So now let's go and look at our presentation for today, Food for the Future Now. To know, challenge, and hope. To feel, relieved and empowered. And to do, act where you are. Creating a new and better world. Creating a new and better world. This is going to be the only thing we need to focus on. The joy of the process, it's really a lot of fun. You can see the happiness in my daughter's face. And even manual food-raising, which is really skill-intensive, not work-intensive, is a lot of fun. The Earth needs our help now. You probably know that already. But this is literally the Earth that's underneath our feet needs our help right now. Let's grow soil. It's not about farming it. It's about growing it. Every time we eat a pound of food grown with regular food-raising practices, an average of 6 pounds in the United States, 12 pounds in developing countries, where 90% of the world's people live, and 18 pounds in China, where 20% of the world's people live, and 24 pounds of farmable soil in California are lost due to wind and water erosion because of the types of practices being used. In contrast, over here on the right, you can see Biointensive Sustainable Mini-Farming has the capacity to build, to grow, to create up to 20 pounds of farmable soil per pound of food eaten-- not deplete 6 to 24 pounds per pound of food eaten, but to build up to 20 pounds of farmable soil, soil we need to feed people. I don't think anyone realizes the number of people that are born each day, really. It's 216,000 people net. That's births less deaths. It's like Motel 6, and the light's on all the time. This is enough to repopulate San Francisco every three days. Wow. Costa Rica every 17. Mexico City, the second largest city in the world, 3.5 times a year. And Beijing, China, 8.6 times a year. What does this mean? It means-- and this is even more important than those population statistics-- it means that 34,000 additional acres of farmable soil need to be found or built daily to feed these people. It's not happening. It's probable that organic farming indirectly results in the loss of three to five and a quarter pounds of farmable soil per pound of food eaten because of the needs of inputs in the form of compost, manure, and organic fertilizer which are taken from other soils. So we may have our perfect organic farm. But we're depleting a soil somewhere else in order to do it. We don't need to. But the pattern we're using now does. Organic farming is a good start. It's a great start. It's a major positive step towards more sustainable agriculture. Yet, we need to take at least three more major steps forward. We need to go beyond organic. The planet is becoming increasingly urbanized. Something that's incredible is India's already 91% urban, China 90% urban. That's 40% of the world's population virtually urbanized. One of the results of this urbanization is that we're losing our farming literacy. We don't really know how to farm. As a result of all these factors, agriculture, as it is, population growth, the loss of our farming skill base, most of the world's soils have become significantly demineralized, compacted, and contain little organic matter unless all these elements have been imported. This isn't a pretty picture. Though, I think the art here is very pretty. You can make a case that the entire planet may be desertified in as little as 69 years. I'm 70 years old. That's in less time than I've been here on the planet. | don't know how long you've been here. But that's a short time. What to do? We need to make farming truly sustainable on as much of a closed system basis as possible. It is possible. We need to grow our own organic matter inputs on the soil we cultivate and recycle all the nutrients-- all the nutrients-- contained in the crops we grow back into the soil. The United Nations Food and Agriculture Organization has noted that 13 years from now, in the year 2025-- that's soon-- about 2/3 of the world's people, 5 billion people, will probably not have sufficient water available for food growing to live a life with reasonable nutrition if at all. We don't have to wait for 2025 for that to happen. We're going to see that happening in just three years, the effect of this.
