Oil is one of the greatest natural resources we have and we will always need oil, we just need to STOP BURNING IT FFS
We won’t always need it. It’ll run out eventually so it has to be replaced at some point. Even if you ignore the climate change part.
If it was restricted to use in necessary cases such as sterile packaging of medical tools, it would last so long as to be effectively forever. Thousands, hundreds of thousands of years.
I wouldn’t be surprised if half of everything you own includes some form of plastic. Phones, cars, appliances, even clothing is made from petroleum.There’s a LOT of things that could be replaced with non-petroleum products (like textiles) but there’s also some fields like medical equipment that we should be saving our reserves for.
