Locally manufactured corn grits for animal feed is pictured at a local market in Manila, Philippines February 16, 2016. A legal challenge to the Philippines' rules on genetically modified organisms is threatening to spark a domestic food crisis, potentially setting a precedent for the rest of Asia. Philippines was the first in the region to allow planting and commercialization of GM corn, which it did in 2002, and has permitted GM crop imports for more than a decade. REUTERS/Erik De Castro

Environmental advocates carry over their heads a giant purple globe, which participants say represents their unhappiness towards genetically modified organism (GMO) products, as they participate in the "People's Walk for Climate Justice", a walkathon against climate change, which started at the Rizal Park in Manila October 2, 2014. The walk, which started today, will cover 1,000 kilometres starting from Manila to Tacloban City in central Philippines where super typhoon Haiyan struck heavily affecting tens of thousands residents. The walk will end on November 8, exactly a year after super typhoon Haiyan made landfall in the province, a organizer statement said. REUTERS/Romeo Ranoco (PHILIPPINES - Tags: SOCIETY ENVIRONMENT)
