Mandatory reminder that this narrative of "individual impact" was created and pushed by oil companies to shift blame from them to consumers.
It is important to keep plastic waste out of the oceans and other places. But I'm not sure if that can't be solved by making sure they get thrown away. There is plenty of space for landfills. Plastic in landfill is carbon neutral. There is energy in making plastic, but there is energy in making the alternatives and from the price, plastic likely uses less.
The other thing is that for climate change, plastic is a pretty small part of the problem, 2% of global emissions. Like it is more important how the restaurant is heated and cooled and how all the customers got there, than what the utensils are made of.
