LEGACIES: KATHERINE GOODBAR: Meet a former Dallas science teacher who instilled the value of conservation into a generation of students ... on Passport to Texas Legacies ... Passport to Texas Legacies from Texas Parks and Wildlife Katherine Goodbar of Dallas, is a former high school science teacher, and current educator at the Richardson Environmental Studies Center. Through her classroom work and frequent field trips, she has introduced thousands of students to the wonders of the outdoors. She says simply studying about the natural world in books is no substitute for being in the thick of it, because it's only when children experience nature that they finally understand its value. "They read something about the natural world and animals in books, but as far as actual knowing - they don't. And to me, the biggest challenge that we have is education. Until you get them out into the field where they can actually relate to the plants that are there, the animals that are there ... that when you see a little snake wiggling through the grass you don't have to scream at the top of your voice and go climb a telephone pole. Contact with natural areas ... field trips ... education. To me that's the challenge. Because if we don't do it - it's hopeless." Mrs. Goodbar has also sought to provide private protection to Texas natural systems through her work with the Natural Areas Preservation Association, the largest Texas-based land trust, which protects over 30,000 acres scattered among more than 65 preserves.
