Climate change is centre stage and our use of land and its effect on the climate are intertwined.

Land is a precious resource. "Buy land, they're not making make it anymore" - in these seven words, Mark Twain captures the mood of a nation. Land is a safe economic resource, until it is not. I am not sure if Mark Twain would have taken the same view with regard to contaminated land and to paraphrase Mr Orwell, "all [contaminated land] is born equal, but some [is] more equal than others".
