It's not a question of whether there is an alternative it's a question about what we are using plastics for. Plastic today is a highly versatile material it can be almost as hard as diamonds, it can be ultra precise like lego and so soft it's weaved into our textiles. You've seen the sorry substitutes for straws? They can't even make that. You won't find alternatives for that and again ex. wind and solar are subsidized without providing any of those benefits. You last comment is speculation and your conclusion even if it was true isn't the only alternative. There are many others. Some of them include us developing methods to deal with CO2 if it turned out to be a problem and you are forgetting the most important thing here. People who don't have access to cheap and plentiful energy are already incurring a debt to survive and paying the piper. There is a cost to NOT using fossil fuels, one very few are ready to make. I for one am not ready to exchange things like food security for the risk of some speculative consequences we dont even know and to the extent we know isn't something we can't deal with.
