Hi, my name is Julia and I'm from Manchester in the UK and my question is do you think we will ever stop using oil?

I think we'll probably have to because I think it's going to run out and I think then so yes I hope so, I hope we can find a suitable alternative. I imagine that when we get to the point where we're desperate, we will, as the human race, we will come up with a solution. Actually, I've no idea what that solution might be in terms of energy. I am not an expert in this field but I do believe that we are resourceful enough and smart enough that we won't allow the planet and ourselves to completely destroy itself.
