Why does La Via Campesina argue that taking the power out of the hands of a few multinational agricultural and food corporations and giving it to the people themselves is key to addressing food insecurity?

La Via Campesina argues that addressing food insecurity requires decentralizing control of agricultural resources and decision-making from multinational corporations and redistributing it to local communities. Centralized power in these corporations leads to an industrialized food system that prioritizes profit and globalization over sustainable, local food production, thereby increasing food insecurity. La Via Campesina promotes food sovereignty, which emphasizes the importance of community control, local farmers' involvement in decision-making, and sustainable agroecological practices. Decentralizing power and returning it to communities allows for the development of policies that prioritize local needs and establish diverse, resilient food systems, thus improving food security.
