After a big holiday meal, the last thing the family wants to hear is you battling with your Uncle Denier about the destructiveness of climate change—rising sea levels, tropical diseases spreading into new territory, dying species, mega-droughts and crop failures. So here's an uplifting alternative. A video not much longer than the usual commercial break that points to a thoroughly positive future. It should leave everyone smiling instead of snarling just in time for the dessert to be dished out.
Enjoy.
