Human
In general, humans can survive for two to eight weeks without food, depending on stored body fat. Survival without water is usually limited to three or four days. About 36 million humans die every year from causes directly or indirectly related to starvation. Childhood malnutrition is also common and contributes to the global burden of disease. However global food distribution is not even, and obesity among some human populations has increased rapidly, leading to health complications and increased mortality in some developed, and a few developing countries. Worldwide over one billion people are obese, while in the United States 35% of people are obese, leading to this being described as an "obesity epidemic." Obesity is caused by consuming more calories than are expended, so excessive weight gain is usually caused by an energy-dense diet.
Water supply and sanitation in Ethiopia
It is important for water to be drinkable and usable for daily use. Without any clean water there would more chances at water related diseases. The World Bank also stated that in Ethiopia from 2011-2015 every 64 in 1000 infants pass away before the age of 1. So in Ethiopia there is a 6.4% chance that one's infant would not be able to survive more than one year. Also take in account that these 6.4% infants are mostly born in the rural areas of Ethiopia.
