delusional climate activists.

Exactly my point, although there is a push to shift away from plastics in some areas

It's delusional to say we need to stop drilling for oil for this very reason.
Ironically if we shift away from fuel burning cars, then the flammable hydrocarbons will be a useless byproduct unless it can be synsythised into other products likely plastics and polymers.

There is an increasing amount of plastics being manufactured from plants. Technology is also developing the use of alternative resources (to hydrocarbons) for combustion requirements, but the biggest challenge facing us is to stop burning stuff, and especially hydrocarbon products.

We've allowed hydrocarbon derived products to dominate our lifestyles over the last century or so and the same innovative skills that have led to that will also provide us with the next phase of human development. Changing from a fossil fueled society to an electronic one will be a substantial effort and will of course cost us in time, money and resources but the alternative is to continue down a path that will likely result in a planet that life as we know it cannot survive on. I don't think we really have any choice in the matter.

The biggest issue with bioplastics is the amount of land needed to grow food such as corn which would otherwise get eaten get wasted into making more single use plastics. Alot of coffee cup lids are made from PLA for example. What about all the energy consumed to produce the stuff?
Plastic sucks, but some environmentalists do t like the thought of burning it in waste to energy plants, but that's the best way to get rid of the stuff out of the environment.
Did you know they can actually make the same polyethylene polymers out of plants now? Those new plant based anchor milk bottles are made of it and can go in your normal recycling, ironically that stuff doesn't readily break down and yet is derived from plants. Mind you I haven't seen them on the shelves lately, perhaps anchor has discontinued them? They not only cost more to consumers who choose to buy them but they were not the "light proof" type either.
Should just go back to glass bottles and refill them like the old days.
