Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
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.
