We need oil gas and plastics. Oil and gas in the short/ medium term (meaning 10-20 years) but plastics potentially for the foreseeable
we have alternative energy sources and so oil and gas should be (needs to be) the priority to wean off of but the scaling up of these needs to be properly managed
Plastics I do not see an alternative to as an end product, however it is possible to use "bio sources" to make plastic precursors so there's a route through there but the scaling is nowhere right now
Single use plastics are a viable target but durable plastics I think are with us for the long term
