I would like to recommend a new 6-part documentary series from American public television, PBS ...
It is an optimistic (but no "rose colored glasses" either
) introduction to work and insights by various researchers, architects, urban planners, agriculturalists, psychologists, biologists, conservationists and the like around the world, hosted by a noted 'futurist' (the son of a WW2 Holocaust survivor) hoping for a better world.
Each episode does offer a message of hope ... if we make the right choices ... if great hurdles can be overcome.
I recommend it to all who believe that our world situation, although dire, has rays of light.
The series is available here, although there may be geographic limits.
