Since the amount of fresh water available for human consumption is constant, as population grows, the supply of fresh water per person declines. As a result, the amount of water available per person is expected to decline by 74 percent between 1950 and 2050. Nearly half a billion people around the world face water shortages today. By 2025, the number is expected to grow to 2.8 billion people. Of these, at least 1 billion people will be living in countries facing absolute water scarcity. Most overpopulated, fast-urbanizing countries of Asia, Latin America and Africa have to survive on largely polluted rivers and wells. Water is a major carrier of disease bearing germs. As many as 2.3 billion people in the world today suffer from diseases linked to water, such as dysentery, cholera and typhoid. Less than 1 percent of the Earth's water is fit and available for human consumption.

Dear Citizen of Earth
The human population of Earth reached 1 billion in 1804, 2 billion in 1927, 3 billion in 1959, 4 billion in 1974 and 5 billion in late 1986. On October 12th 1999, the human population of Earth reached 6 billion. The population has more than doubled in the last 50 years. This doubling of population which occured over the last 50 years will never come close to happening again.
