4x29 - The Berenstain Bears

Looking for something to do their environmental school project on, Brother and Sister visit Professor Actual Factual at the Bearsonian Institute. Not only do they discover that too much trash in Bear Country is a big problem, they also learn about endangered species such as the Bumbleberry tree - one of which Papa is intending to cut down to make a very special table and chairs. By showing them how to recycle eggshells as plant fertilizer, Mama helps the cubs discover that even little cubs like them can help reduce waste. Not only do the cubs spread the word to their friends who come up with their own ways to recycle, they help Papa realize he should help the environment by planting new trees instead of cutting them down.
