- There is the same amount of water on Earth as there was when the Earth was formed. The water from your faucet could contain molecules that dinosaurs drank.
- Water is composed of two elements, Hydrogen and Oxygen. 2 Hydrogen + 1 Oxygen = H2O.
- Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.
- Water regulates the Earth’s temperature. It also regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes.
- 75% of the human brain is water and 75% of a living tree is water.
- A person can live about a month without food, but only about a week without water.
- Water is part of a deeply interconnected system. What we pour on the ground ends up in our water, and what we spew into the sky ends up in our water.
- The average total home water use for each person in the U.S. is about 50 gallons a day.
- The average cost for water supplied to a home in the U.S. is about $2.00 for 1,000 gallons, which equals about 5 gallons for a penny.
- Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water.
- Around the world 59 million children of primary school age are being denied an education, and almost 65 million adolescents are without access to a secondary school.
- Conflict and natural disasters have disrupted the education of 75 million children.
- In one of three countries, less than three quarters of teachers are trained to national standards, resulting in 130 million children enrolled in school who are not even learning the basics.
- A child whose mother can read is 50 percent more likely to survive past the age of 5.
- Nearly 15 million girls of primary school age will never have the opportunity to learn to read and write in primary school, compared to about 10 million boys.
- It would take $39 billion (USD) every year to send all adolescents to school.
- In 2012, there were 168 million child labor workers aged 5 to 17. This is one reason many children cannot attend school.
- Over 40 years, equitable access to quality education can help a country raise its gross domestic product per capita by 23 percent.
- If all women had a primary education, there would be 1.7 million fewer malnourished children.
