Document Summary
Sanitation: hygienic means of preventing human contact from the hazards of waste to promote overall health. No access: less then 5l (very high health implications: people will need to rely on water that is not safe. Basic access: does not exceed 20l per person day (high) In a lot of developing countries this is the average/best case senerio. Optimal access: average 100l (very low health concerns) Americans get an average of 300l of water a day. The more people we have the greater the demand. There is a lot of water but irl tiny fraction is fresh water, and a lot of it is inaccessible. For example water from ditches to drink to clean themselves etc. Where the population is growing the fastest a lot of the population does not have access. Global climate change which is leading to a loss of access to water due to evaporation, and joined with population pressure creates strains on the resources.
