It is so surprising that we can make half a greenhouse’s wall out of a weeks bottle consumption on Berks campus. Approximately, there are over 500 plastic bottles being tossed away in the library every week and based on the calculation, finishing this greenhouse, 3,000 plastic bottles are enough. We cut the bottom of the bottle and put the bottles on the bamboo sticks. Then we nail the bamboo into the wooden frame. This project really should ring the bell for us that there are so many bottle consumptions every weeks, that could cost a lot of money to even recycle. Don’t be afraid to drink tap water.
