Beautifully done, HOME is a movie which you can watch online for free.
Summary so you can see if it's something you'd like to watch 
"We are living in exceptional times. Scientists tell us that we
have 10 years to change the way we live, avert the depletion of natural
resources and the catastrophic evolution of the Earth's climate.
The
stakes are high for us and our children. Everyone should take part in
the effort, and HOME has been conceived to take a message of
mobilization out to every human being.
For this purpose, HOME
needs to be free. A patron, the PPR Group, made this possible.
EuropaCorp, the distributor, also pledged not to make any profit
because Home is a non-profit film.
HOME has been made for you : share it! And act for the planet."
So I'm sharing:
