No need for dichotomy here. Both types of pollution (heat trapping molecules and plastics) are waste from a consumption culture that doesn't think long term about material life cycles. When we make progress as a species, we will realize that all environmental impact is interrelated and needs to be assessed well before we "move fast and break things"

Right, the likely answer is both will kill us, and many of these things seem to be correlated in so many ugly ways.

Let's not forget also that Plastics are "cheap" to consume precisely because they originate as by-products/waste-products of fossil fuel consumption. One consumption problem indirectly produces the other.
