Two of the five nominations in the category of Documentary Feature for this year’s Oscars deliver serious green messages.

The Cove is a gripping tale that chronicles the annual slaughter of thousands of dolphins in a cove near the Japanese village of Taiji. Fishermen use sonar to confuse and trap the dolphins then sell the meat fraudulently as whale meat. The mislabeled product, which is dangerously high in mercury, ends up in the lunches of school children in Japan.

The film, which was directed by former National Geographic photographer, Louie Psihoyos, used free divers with state of the art equipment to infiltrate the cove and expose the shocking massacre.

“The Cove exposes not just a horrific yearly hunt, but humans knowingly poisoning other humans by slipping dolphin meat into the food system,” Psihoyos wrote on Huffington Post. “Dolphin meat is through-the-roof toxic because of high levels of mercury, the most toxic non-radioactive element in the world. Dolphins have anywhere from five to 5,000 times more mercury than allowed by law.”

Food, Inc promises, “You’ll never look at dinner the same way.” In the film, director Robert Kenner exposes the hidden truths about the food we buy at our local grocery stores. Food, Inc, which is narrated by Michael Pollan (The Omnivore’s Dilemma) and Eric Schlosser (Fast Food Nation), reveals the cruel and unsanitary conditions in the U.S. food industry, an industry which disregards consumer health, worker’s safety, and the environment — for the sake of profit.

Recently Food, Inc was featured on Oprah’s show dedicated to revealing the truths about the food industry. “For me, it boils down to making more conscious food decisions,” Oprah said on the show. “That is my opinion. I saw the movie. That’s how I felt. But you need to see it for yourself and make your own decisions because I believe you have a right to know where your food is coming from.”

The Oscars will be broadcast live on March 7 at 8 p.m. ET on ABC. Let’s hope one of these films receives top honors.
