Catherine Knoop

Member Since 1987

Catherine Knoop’s personal and professional life is a tale of unwavering commitment to education and environmental stewardship, marked by an innovative approach to teaching and a global perspective on environmental issues.

Cathy dedicated most of her decades-long career to teaching elementary science in the Troy City School and Logan Elm School District of Ohio. Her pioneering use of “land labs,” or lessons outside a walled classroom or school building, was not common 40 years ago and set her apart for her ingenuity. Her success was evident in her students’ high scores on state tests, achieved without relying on conventional drill and practice methods. Her goal was to prepare her students to be globally aware citizens, conscious of humans’ environmental impacts on the planet.

Cathy’s involvement with Population Connection began with her fascination with our Population Education activities, which she eagerly incorporated into her classroom. She has also served as a teacher-training volunteer for the Population Education program, offering countless workshops to her fellow educators to help expand our reach over the years.

She resonates deeply with our mission, recognizing that overpopulation negatively affects people’s quality of life and the planet’s chances at environmental sustainability. Cathy sees education as the key to raising awareness and affecting change. She attributes her understanding of the population-environment nexus to authors like Paul Ehrlich and Rachel Carson, who inspired her to develop a “sense of wonder” in children and adults.
