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.

	worse for the planet	better for the planet
worse for your body	newly-produced plastic	second-hand plastic
better for your body	newly-produced plastic-free	second-hand plastic-free

also btw: bodies ⊂ planet
