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.
Harmony with nature
16. Without water, there is no life. Humans and all living things have the right to water, but water also has rights. All States and peoples worldwide should work together in solidarity to ensure that loss of vegetation, deforestation, the pollution of the atmosphere and contamination are prevented from continuing to alter the hydrological cycle. These cause desertification, lack of food, temperature increase, sea level rise, migrations, acid rain, and physical-chemical changes that can cause ecosystems to die.
