It's because it's just delaying the issue, that's why. The theory is that if we get oil for a while off the cost that will give us time to make alternatives. The reality however is that like a highschool fuckwit, we use our extended date to do nothing but slack off more untill the last minute and then try and fix the problem at a time when the situation will probably be worse.
