Think of all the energy used in collecting the plastic (gas, oil, and emissions from dump trucks that pick it up, for example), sorting it, disposing of what isnt recyclable, and actually recycling the stuff.
Im no expert but I believe that overall recycling as we do it is actually a net negative on the environment. We're probably doing more harm than good.
Well we can move cars with electricity so i guess it could do some good as some point
That said I'm in the train of let's actually accelerate climate change it's not like no one is going to move a finger till it gets really bad so why should we extend the suffering
