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.

Ultimately, the only wealth that can sustain any community, economy or nation is derived from the photosynthetic process - green plants growing on regenerating soil.

We simulated the predator with livestock and the perennial grassland returned. Just put the whole back, and there it was. You'll find the scientific method never discovers anything. Observant, creative people make discoveries. But the scientific method protects us from cranks like me.

Burning one hectare of grassland gives off more, and more damaging, pollutants than 6,000 cars. And we are burning in Africa, every single year, more than one billion hectares.

People and land need healing which is all inclusive - holistic.

Almost all the knowledge required to produce more food than eroding soil is available today - we just need to use that knowledge within a holistic paradigm - managing agriculture holistically, forming the policies that undergird it holistically.
