Selain sinar mentari, air ialah hal terpenting di dunia bagi hampir semua makhluk hidup. Sebagian dari kita barangkali berpikir bahwa bumi yang kita tumpangi ini mempunyai banyak air sampai-sampai kita memperlakukan air menyerupai barang yang jumlahnya nyaris tidak terbatas, tapi apa betul begitu? Di bawah ini ialah data-data mengenai air yang kami rangkum dari banyak sekali sumber. Selamat membaca dan jangan lupa sebarkan info ini.

United States Environmental Protection Agency
  1. Only 3% of earth’s water is fresh water.  97% of the water on earth is salt water
  2. 0.3% of the world’s fresh water is at the earth’s surface in lakes, rivers, streams, ponds, and swamps
  3. 68.7% of the fresh water on earth is trapped in glaciers
  4. 30% of fresh water is in the ground
  5. American residents use about 100 gallons of water per day
  6. Americans use more water each day by flushing the toilet than they do by showering or any other activity
  7. At 50 gallons per day, residential Europeans use about half of the water that residential Americans use
  8. Residents of sub-Saharan Africa use only 2-5 gallons of water per day
  9. The average faucet flows at a rate of 2 gallons per minute
  10. A five-minute shower uses 10 to 25 gallons
  11. It takes more than 10 gallons of water to produce one slice of bread
  12. It takes over 713 gallons of water to produce one cotton t-shirt
  13. It takes roughly 634 gallons of water to produce one hamburger
Lenntech Water Treatment Solutions
  1. It takes 5,680 litres (1,500 gallons) of water to process one barrel of beer
  2. It takes 450 litres (120 gallons) of water to produce one egg
  3. It takes 44 litres (11.6 gallons) of water to process one chicken
  4. It takes 7,000 litres (1,850 gallons) of water to refine one barrel of crude oil
  5. Most of the world's people must walk at least 3 hours to fetch water
  6. Today, at least 400 million people live in regions with severe water shortages
  7. Approximately 66% of the human body consists of water. Water exists within all our organs and it is transported throughout our body to assist physical functions
  8. 75% of a chicken is water
  9. 80% of a pineapple is water

  12. Two thirds of the water used in a home is used in the bathroom
  13. To flush a toilet we use 7.5 to 26.5 litres (2 to 7 gallons) of water

United Nations-Water
  1. Global population growth projections of 2–3 billion people over the next 40 years, combined with changing diets, result in a predicted increase in food demand of 70% by 2050
  2. With expected increases in population, by 2030, food demand is predicted to increase by 50% (70% by 2050) (Bruinsma, 2009), while energy demand from hydropower and other renewable energy resources will rise by 60% (WWAP, 2009). These issues are interconnected – increasing agricultural output, for example, will substantially increase both water and energy consumption, leading to increased competition for water between water-using sectors
  3. Water availability is expected to decrease in many regions. Yet future global agricultural water consumption alone is estimated to increase by 19% by 2050, and will be even greater in the absence of any technological progress or policy intervention
  4. Water for irrigation and food production constitutes one of the greatest pressures on freshwater resources. Agriculture accounts for 70% of global freshwater withdrawals (up to 90% in some fast-growing economies)
  5. Producing 1 kg of rice requires 3,500 litres of water
  6. Producing 1 kg of beef requires 15,000 litres of water
  7. Producing a cup of coffee requires 140 litres of water
