I agree with the hon. Gentleman that there is probably a break-even level of about $5 a barrel and, therefore, the major oil companies will continue to produce even if oil prices fall to that level. However, does the hon. Gentleman agree that, at that level, or just above it, the major oil companies will not be exploring for the next decade's oil or for the heat, power and motive force that will provide for the next generation? I am sure that the hon. Gentleman would agree, and I would like his comments on that.
