All the water and air on earth gathered into spheres and compared to the Earth

Fantastic post on Boing Boing showing a computer simulation of all the water on the earth(left hand side)- which includes sea water, clouds, glaciers, underground water etc. On the right is all the air on earth. Both these images represent water and air at the same scale as the earth.

As explained on the science photo website:

Global water and air volume. Conceptual computer artwork of the total volume of water on Earth (left) and of air in the Earth’s atmosphere (right) shown as spheres (blue and pink).

The spheres show how finite water and air supplies are. The water sphere measures 1390 kilometres across and has a volume of 1.4 billion cubic kilometres. This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the atmosphere.

The air sphere measures 1999 kilometres across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometres of the atmosphere.

How important is spelling… really

I have to confess that I don’t have the greatest attention to detail. But what I saw next really proves that spelling isn’t that necessary.

A really cool animated map showing the spread of religion – 5,000 years in 90 secs. While not food related I found it quite interesting to see the spread of ideas over the millenia.

What the World Eats

Time magazine has released a great photo essay of what different families in different parts of the world eats. What is amazing is how much we spend on food each week and how much of that food is processed. You can see the photos here:

Which nation wastes the most water?

Australia.
We use water in the most unusual ways. It takes about 8,000 litres of water to make a pair of leather shoes. Each kilo of steak took about 16,000 litres of water to produce. A friend of ours works on a think-tank (no pun intended) on water usage in Qld and was telling us about the problems facing coal mines – apparently they use huge quantities of water.

Even a simple bag potato chips use or COST about 185 litres to make. We are so dependant on water that it is easy to see how many civilisations have collapsed because of water shortages. Even in this modern age, our economies and industries are totally entwined with our water resources. 10% of our water is consumed domestically, industry gobbles up the rest.

This is why the Queensland government is so desperate to control the water… it’s not about water… it’s about jobs and the economy.

How much energy was used to make your food

We all know to check our food labels for fat content etc… after all, fat is important to us. But what about the environment? Open the Future have the sort of food label that will affect your kids, grandkids etc. It’s how much energy and fossil fuel is used to make your product. Just a concept at the moment:

We are so obsessed with ourselves that we forget about others and the future. Bottled water is another energy wasteful product. Water is taken from a place like Fiji or Mount Franklin, bottled in plastic (which is an oil based product) then shipped to your supermarket or shop (burning petrol or diesel on the way) and then the bottle is thrown in the trash where it takes hundreds of years to break down. The most economical and environmentally friendly water delivery system is the pipes in the ground… maybe we just have too much money, after all, we pay more for water than we do for petrol and yet we complain about petrol prices.

Glad to get that off my chest this week.

Giant Roman Shipwreck Yields "Fishy" Treasure

Fish sauce called Garum was a valuable ancient Roman sauce/flavouring and was traded and coveted by Roman soldiers. An ancient roman shipwreck off the coast of spain has revealed hundreds of amphorae that still contain Garum. Apparently Romans loved Spanish garum the best and there was a lot of trade between Spain and Italy.

Here is an ancient recipe for garum:

Ancient Garum Recipe Use fatty fish, for example, sardines, and a well-sealed (pitched) container with a 26-35 quart capacity. Add dried, aromatic herbs possessing a strong flavor, such as dill, coriander, fennel, celery, mint, oregano, and others, making a layer on the bottom of the container; then put down a layer of fish (if small, leave them whole, if large, use pieces) and over this, add a layer of salt two fingers high. Repeat these layers until the container is filled. Let it rest for seven days in the sun. Then mix the sauce daily for 20 days. After that, it becomes a liquid.
