Allan Savory

"I've often been asked what drives me, particularly through the last 50 years of abuse, and ridicule. What has kept me going is one word - care. I care enough about the land, the wildlife, people, the future of humanity. If you care enough, you will do whatever you have to do, no matter what the opposition."

"The problem with holistic management is it's so profoundly simple, but it's not easy. And it's profoundly simple. You're almost insulting people's intelligence to explain it twice, just about making better decisions of where you want to go in your life, bringing in environmental, social, economic issues simultaneously."

"People in all walks of life, and especially business, do not want to experience the collapse of cities like New York along with global finance and economy in chaos, but this is what business faces if we continue to attribute climate change to fossil fuels alone."

"Agriculture is not crop production as popular belief holds - it's the production of food and fiber from the world's land and waters. Without agriculture it is not possible to have a city, stock market, banks, university, church or army. Agriculture is the foundation of civilization and any stable economy."

"We need to manage holistically, embracing all of our science and traditional knowledge - all sources of knowledge. We can do that from the household to government to international relations."

"Hard systems are everything we're using right now - computers, phones, planes, the clothes you're wearing, the room you're in. Everything there involves 100% use of technology and expertise to make it, and nothing we make - including space exploration vehicles and so on - is complex. Everything we make is complicated. Nothing is self-renewing."
