"London Crawling – Talking About Population" is a short film from Population Matters, directed by Tom Martin of the Media Trust. Britain’s population has grown by one third since 1950 and London’s population is now approaching nine million, with an additional million inhabitants expected over the next ten years. London’s experience is that of many cities worldwide, while global population is increasing by 80 million – the size of Germany – every year. Are we talking enough about the issue of population? And how can we achieve a sustainable population, both locally and globally?
