Brilliant, and at the same time quite horrifying piece of TV. The scenes with the Shearwater chicks being induced to vomit up bits of plastic was particularly shocking, along with the Indonesian river. Agree with others, it does at least feel like there is a rapidly increasing realisation that something drastic needs to be done, but the task now is so, so massive. If we can at least stem the bleeding that would be a start, but even that will take years to get some countries on side.
