That's true, we need fossil fuels for so many things besides transportation. At the same time, we are simply running out of fossil fuels. Even if we ignore the impact on the environment completely, there will be a point in the not too distant future when there will simply be nothing left to pump.
So what I am wondering is, even if one thinks man made climate change is a hoax or something similar, shouldn't the first and foremost thing everyone agrees on be to still spare those scarce resources? For things we really ("really") need to make from oil?
The first thing that comes to mind (maybe since I work in the lab) is medical equipment. You don't really want to have to wash and reuse things like catheters, do you? I am not sure if bioplastics (i.e., still plastics, but made from plants) would be an alternative here once we run out but I sincerely hope so.
Prices will go up, in any case, and it will be a painful transistion. But now we are at a somewhat luxurious point where we can still make this transistion somewhat controlled and "smoothly". If we continue to treat oil as a never ending resource and then do a surprised pikachu face once there is nothing left this will be much much worse, won't they?
