Humans are the cause of climate change.  Climate change is also biodiversity loss, desertification, mega fires and climate change that are all feeding off each other and spiralling out of control.  The way humans manage fossil fuels, livestock, and the the environment is what is leading to the continual degradation of the natural world.  In the 1960's Allan initiated an elephant culling program in an effort to protect native habitats in Rhodesia (Zimbabwe today) from over grazing. The results were devastating.  Not only were thousands of elephants killed, but the land degradation became worse. This led Allan to the conclusion that grazing animals were a critical component of all grassland systems. In fact, there is nothing available in the world that can reverse desertification other than livestock. In 1983, Allan and 2000 scientists from across the world identified that universal reductionist management was the key driver of climate change and developed the holistic framework.  In 2009 Allan founded the Savory Institute (https://savory.global/) to  facilitate regeneration of the world's grasslands and the livelihoods of their inhabitants through holistic management.  Reductionist management ignores the complexity of our societies, economies, and nature and focuses primarily on addressing symptoms rather than the root cause. Reductionist management of our resources has led over thousands of years to the ever increasing degradation of the natural life support systems we all rely on for our survival. According to Allan government policies that cut fossil fuel use and livestock numbers will do little to address climate change if they are developed holistically. The reason governments as so critical to our ability to combat climate change is that governments are the only institutions that can manage at scale. To address the unintended environmental consequences of our current managements of all natural resources policies need to be implemented at the scale required to achieve real impact.  I recently caught up with Allan to hear more about his work, you can listen to a short summary followed by our full conversation here.
