Simple increase in the quantity of food sources does not solve problem of malnutrition. Why?
All of these.
The problem of malnutrition needs to be addressed in a multifaceted manner. Many people live in remote areas, are very poor and thus do not have access to good nutritious food. Farmers face severe financial crisis and are mostly unable to sustain themselves in agriculture, thus decreasing the amount of cultivable land. Solving these problems are very important to eradicate malnutrition.
