Trash bins! I’d love to see functional trash bins in the game. Especially, if they have appropriately ironic slogans printed on the side when examined.
Examples include:
“Do Your Part! Save Our Planet!”
“Don’t Let Our World Perish! Recycle!”
“Go Green for Life!”
“Go Green Or Die!”
“Nature Saves Us, We Must Save Nature”
Also, some (or all) bins could provide permanent disposal for whatever is thrown into them.
