I was appalled at the cooler/fertilizer pack included. The plastic is non-recyclable. There are no directions on how to use it as plant food, and if you don't use it all, its contents WILL end up leaking into waterways, contributing to algal blooms and environmental hypoxia. PLEASE find another way to cool box contents, IF AT ALL. From here on, I will order several packs of energy bars only in winter, and will refrigerate them. Thanks for considering.
