our bodies and the planet are in a cooperative game:

There is so much plastic stuff in the world.
We should produce less stuff in general.
We should produce less stuff made out of plastic.
We should make the healthiest possible use of the plastic that already exists.

	bad for the planet	good for the planet
bad for your body	newly-produced plastic	second-hand plastic
good for your body	newly-produced plastic-free	second-hand plastic-free

also btw: bodies ⊂ planet
