What industry helps most people in the underdeveloped countries of the world support themselves?

The agriculture industry plays a crucial role in helping people in underdeveloped countries support themselves. It provides employment opportunities, sustains local economies, and ensures food security for communities. Many rural populations rely on subsistence farming, which not only feeds families but also generates income through the sale of surplus crops. Additionally, agricultural initiatives can empower farmers with training and resources, fostering sustainable practices and improving livelihoods.
