Kyrie Irving wants to preserve clean water for the Sioux Nation, and Jaylen Brown wants to save the bamboo trees - and possibly the giant pandas, mountain gorillas and lemurs that feed off them. I can't see sound arguments against either cause.
Jaylen is using a series of videos, and his advancing celebrity status, to support a cause that I would be glad to argue for. Looking at both Kyrie and Jaylen's causes, I live in very-northern New England, with clean air and water.
