Happy World Water Day !
"There are 7 billion people to feed on the planet today and another 2 billion are expected to join by 2050. Statistics say that each of us drinks from 2 to 4 litres of water every day, however most of the water we ‘drink’ is embedded in the food we eat: producing 1 kilo of beef for example consumes 15,000 litres of water while 1 kilo of wheat ’drinks up’ 1,500 litres.
World Water Day: What’s your water footprint?
...."And, the average water footprint for a Canadian is 6,392 litres a day — that’s the total volume of freshwater used to produce the goods and services we consume.
Here’s the down low on H2O:
70 per cent of the world’s water is used for agriculture
1,755 litres of water required to make one sausage.
160 litres of water is used to produce one large banana
230 litres of water are used to make one 200-ml glass of apple juice.
1,040 litres of water are used for 1 kg of potato chips
50 litres of water is used to produce one tomato; about 530 litres to produce 1 kg of tomato ketchup
500 litres of water goes into producing 100 grams of cheese
1,260 litres of water goes into one margherita pizza
120 litres of water is used to make a 125-ml glass of wine
74 litres of water is used to make a 250-ml glass of beer
30 litres of water is required to grow enough tea leaves to make a single cup of tea
30 percent of the food produced worldwide is lost or wasted every year.
50 per cent reduction of food losses and waste at the global level would save 1,350 cubic kms of water a year. (By comparison, the volume of Lake Ontario is 1,640 cubic kms.)

Statement: Challenging the World Water Forum to protect water from corporate control
Statement by Shayda Naficy, Senior Organizer, Challenge Corporate Control of our Water

This week, the World Water Forum (WWF) will convene representatives of the water industry, other major corporations and government officials in Marseilles to shape international water policy such that it prioritizes for-profit models of water delivery, and profit-oriented allocation of the world’s most essential resource. At the same time, over 2000 people from global civil society will be converging on Marseille to challenge the official forum and propose an alternative, democratic space for policymaking. The World Water Forum and its illegitimate declarations are being used to undermine recent advances in the recognition of the human right to water at the United Nations, and to promote commercialization of water in development goals and commitments.

1. How much water is on Earth?
In this illustration, the blue ball represents the volume of all the water on earth, relative to the size of the earth. The tiny speck to the right of the blue ball represents Earth's fresh water.CREDIT: David Gallo/WHOI
If Earth was the size of a basketball, all of its water would fit into a ping pong ball.
Oceans create a water layer spanning 15,000 miles (24,000 kilometers) across the planet at an average depth of more than 2 miles (3.2 km). If you poured all of the world's water on the United States and could contain it, you'd create a lake 90 miles (145 km) deep.
This seems, and looks, like a lot of water, Gallo told Life's Little Mysteries, but looks can be deceiving.
If the Earth was an apple, Gallo said, the water layer would be thinner than the fruit's skin.
The Earth's freshwater is even rarer.
