Starvation(hunger) and poverty

Starvation is mainly caused by the uneven distribution of wealth and sometimes by war or natural disasters. We can reduce starvation by redistributing the wealth of rich countries, by providing education and technology to developing countries, and by giving monetary aid to disaster-stricken areas.
