Allan Savory — Zimbabwean Scientist born on September 15, 1935,

Allan Redin Savory is a Zimbabwean ecologist, farmer, soldier, exile, environmentalist, international consultant, and president and co-founder of The Savory Institute. He originated holistic management, a systems thinking approach to managing resources. Once a staunch opponent of livestock, Savory would come to favor using properly managed livestock, bunched and moving to mimic nature, as a means to heal the environment, stating "only livestock can reverse desertification. There is no other known tool available to humans with which to address desertification that is contributing not only to climate change but also to much of the poverty, emigration, violence, etc. in the seriously affected regions of the world." "Only livestock can save us." He believes grasslands hold the potential to sequester enough atmospheric carbon dioxide to reverse climate change. Praised by supporters as genius, prophet and visionary, his controversial ideas have sparked fierce opposition from academics, environmentalists, and vegans. Yet his radical approach is gaining ground, with new converts and investors, and total grassland under holistic management topping 40 million acres worldwide... (wikipedia)

If you dig deep and keep peeling the onion, artists and freelance writers are the leaders in society - the people who start to get new ideas out.
