It behooves us to vastly slow our our use of fossil hydrocarbons, not only because of the danger of global warming, but because it is all finite material which future generations will find useful. Think of the amount of easily claimable oil and gas which we have sucked up in the past 150 years or so, and how little will be available for the next several millennia. Your descendants may want some fossil hydrocarbons for waxes, lubricants, medicine, fertilizer, heavy industry, asphalt, refrigeration, household cleaners, glues, many forms of plastics and elastics, and on and on. 
We are so fortunate with what we have today. Too bad for the future.
