Packaging
When buying items, choose products with minimal packaging preferably made of recycled materials (item will state, “__% of post-consumer content”), that are, in turn, recyclable.
Remember, consumers pay for packaging, first through the costs to make it and then through the costs to dispose of it.
All of the alternative choices below are no more inconvenient than the original choices. In addition, some also save you time, and all save you money. Finally, they all help us green up our world.
