Jewish actor Liev Schreiber helps out with the JNF's Project Renewal, planting trees in Israel's Galilee region, where some 750 thousand trees were destroyed by rocket attacks from Hizbollah.

Mr Schreiber, who starred in the X-Men prequel Wolverine and the Holocaust film Defiance, is joined by his partner Naomi Watts and their two sons Sasha and Sam.

Praising the JNF's work planting more than two million trees, Mr Schreiber says in the film that his family "are continuing with that tradition".
