The Corvallis Advocate

In June of 2018, Worthy Garden Club hosted Dr. Bill Ripple, distinguished professor of ecology in the Department of Forest Ecosystems and Society at Oregon State University, for his first lecture on "What Wolves Can Tell us About the Word's Health." Ripple became involved in climate change activism after researching wolf reintroduction in Yellowstone Park, leading him to study the beneficial role of large predators in ecosystems throughout the U.S. as well as global trends in rising animal extinction rates, decreasing freshwater availability, forest area loss and extreme weather events. The all appeared to be tied to an increase in human and ruminant livestock populations as well as carbon dioxide emissions. So, 25 years after the "World Scientists' Warning to Humanity," Ripple co-authored the "Second Notice,"cautioning that “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.”  He recently founded the Alliance of World Scientists, an International assembly of over 14,000 scientists, independent of both governmental and non-governmental organizations and corporations, which aims to be a collective international voice of many scientists regarding global climate and environmental trends and how to turn accumulated knowledge into action. He is one of the loudest voices in the scientific community surrounding climate change solutions and continues to fight for an informed, common-sense approach to our climate emergency.


We recognized Dr. Ripple's work and potential impact on the conversation around climate change back in 2017. After the overwhelming response to our first public lecture with Dr. Ripple at Worthy, we sponsored a statewide lecture series with the goal of shedding light on our global climate crisis and presenting compelling research that leads to decisive public and legislative action.  We continue to support Dr. Ripple's research and are proud to be an important funder for his latest work to gain international attention, the "World Scientists' Warning of a Climate Emergency."
