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.

In this exciting excerpt from the third season of Jonathan Bird’s Blue World, Jonathan films a hermit crab changing shells and then also transferring its anemones from one shell to the other. This is extremely rare footage of a seldom-seen behavior!
