Eureka, Ca., (KIEM)- The Sequoia Park Zoo starts the year by encouraging children of all ages to interact with nature. Their program to promote environmental stewardship is called “Nature Exchange.” Visitors to the zoo are encouraged to bring items they find in nature, things like empty shells, driftwood, and rocks. Those items are exchanged for ‘points’ that can be turned in for items like porcupine quills and antler sheds. The goal is to encourage families to spend more time outside. The other hope in encouraging gentle collecting is to help children develop stronger observation and critical thinking skills.
