All true, but I think we should FIRST set out the rules & conditions of fracking before we drill and study whether there is gas.   What we are doing now is negotiating what to wear and what time your 14y old daughter must be home before even agreeing whether she can go to the club at all.

I have a simple test for the frackers : frack all you want BUT only if you do so with unlimited liability backed by a suitable global insurance policy that will cover rehabilitation.   None of this, comply to regulations you helped write, or such exit clauses.   FULL unlimited liability insured

Since fracking is so safe and healthy you should be 150% OK with such a condition.   Right?
