Venice, August 26 - Organizers of the historic Venice Film Festival together with the environmental organization Green Cross and the city of Venice said on Monday that a special award for the most environmentally sensitive work will be presented for the second year running at this year's 70th edition. The Green Drop Award will be presented to the film deemed as best portraying the values of ecology and sustainable development, the preservation of the planet and its ecosystems, as well as cooperation between peoples. Italian film director and screenwriter Mimmo Calopresti will head the jury, which will also include actress Ottavia Piccolo and climate expert Vincenzo Ferrara. Twenty films will be competing for the prize - a drop-shaped vase, blown by a master glassmaker, containing a sample of earth from each country that entered a work. "The drop symbolizes the strength of each small action and the power of film, which can stimulate our daily behavior and make us more attentive to the environment," said a release by the city of Venice.
