Do you meditate that grease will bottom out?
Answers:
Only when we start using alternatives to petroleum for fuel, business, etc. The grease companies will confrontation until Doomsday to suppress any alternative technology that would put them out of business, or even that would moderate their flea market share. Just look at what GM did near the EV1 electric car- recall them adjectives at the ruin of the lease agreements, and SHREDDED the cars preventing reverse engineering.
But, something have to dispense soon, previously we run out of grease and ruin our planet.
Never. Too several population and far too much misuse! :-(=
