Essentially, my kids grew up with the emphasis on the environment because I became a political activist in about 1969 and it was not an easy time. Those were the days when the oil and gas companies pretty much controlled the show and anybody speaking about solar energy or carbon energy would get smashed down as being a radical or a tree-hugger or what have you. So I was out there feeling very often alone and my kids would get that.

I think there was something that made us not pay attention to climate change. Something that was up there. There was a saying when we were trying to pay attention to the environment that people used this phrase NIMBY - not in my back yard. People were saying, ‘I don’t care, it is not in my back yard.’ But now it’s in everyone’s back yard.

Generally speaking, I went through that. I came to a place where I realised what true value was. It wasn't money. Money is a means to achieving an end, but it's not the end.
