Great presentation. It was very easy to follow. I thought your explanation of the + and -- flows was well explained too; but some of it seemed counter-intuitive when you went on to further examples. If you do a similar video then explaining it again for the first few examples may help the penny drop for people like me....who think too hard! Thanks for posting, though. It was an excellent video (yet again!)

The illustrations made the topic quiet easier to understand.

More on-screen images would have made this nicer

The black balloons in the air to represent emissions is a horrible idea. All that plastic/rubber floating in the atmosphere, trashing the skies and creating environment hazards. We obviously don't think stuff through.
