Simple idea, but great idea
You probably know what Starbucks is? and how many cup they spend in one day?
Now imagine that every single cup is capable of being a tree? it could be wonderful if every cup spent each day, where being transformed into a real tree. this is the utopia of Joon Kim a famous designer. in each cup you’ve got a little seed and inside the cup you’ve got a disc fertilizer. this way you juste have to take seed give some water and wait until you’ve got a little tree.
this idea is pretty cheap but the consequences on our planet are huge. all the little thing we can do for our planet, will be one day rewarded, be sure of that.
