Yeah there's should be sufficient food for everyone. Many Non Government Organizations are supporting to solve this problem but this still existing to those undeveloped countries. This is a results to a corrupt government whose administrations has not focus on the development of the country rather than taking the wealth of the country to support weapons and illegal gatherings. In my opinion, you can't permanently end hunger by giving them foods. The government should give them a proper education and livelihood program to sustain their daily needs.
