I know that, you defecating drooling ape. There are machines that pressurise and break down plants in such a way that they eventually turn into crude oil - a sped-up version of the process that turned those ancient plants into oil in the first place. We can also extract oils from some plants as-is: rapeseed, olive, and sunflower oil are widely used in cooking, for example. How you don't know this is beyond me.
