The US exports its most valuable assets

In the last decade, however, these wells have begun to dry up. Walk through the houses and farms run by families you will see why – thousands of acres of neatly connected trees with pecans and pistachios, large fields of beans and corn, large dairy cows, and rows of tomato plants growing in the desert the former was empty. . This large-scale industrial agricultural carpet, which contains food grown for export to other parts of the world, takes deep wells for storage. For every 100 acres or so, a farm owner digs a well up to 2,000 feet[2,000 m]and draws water from old water up to 2,000 gallons[2,000 L]per second, usually 24 hours a day. Oil refineries are often similar to those used in oil production.

There are almost no laws for the extraction of groundwater in Arizona. As long as the farms pay the right amount, they can pump as much as they want.

In addition to removing more water from the water, Arizona (along with Southwest America) is now experiencing one of the worst droughts in centuries, probably due to global warming. When the area is very hot and dry, which requires a lot of extraction from the water, less water comes out of the monsoons or snow to expand.

What we do not find related to the water cycle

At school we teach children about the movement of water, how water flows from the ocean to the surface to freshwater springs and eventually returns to the ocean. In these words, the water we use is never running out.

But these myths confuse something important: the water cycle can take decades or hundreds of years to complete. Most of the fresh water we use every day comes from groundwater, which can take hundreds or thousands of years to accumulate. If we use water as fast as it can, or waste it and dump it into the sea faster than natural water can purify, the source will be depleted.

If you instead think of water as a last resort used in the same way as oil or gas, you start to see its availability in every economic sector. More than 70% of the water we use is produced for food production, e.g. But water is also used to make everything from T-shirts to cars to computer chips.

If they can’t find enough water in their limits, the thought goes, why not just put them (included in food) from somewhere?

Like its carbon footprint cousin, a water pump can be a quick way to help you understand how the environment affects the environment — or yours. Coffee cup water is about 140 liters, for example. It takes about 15,000 gallons[15,000 L]for beef to grow one pound[1 kg]. A few slices of bread can hold up to 100 gallons[100 L]. One kilogram of cotton (jeans and a shirt, as it were) can accommodate anything from 10,000 gallons[22,000 L]to more than 22,000 gallons, depending on the size.

This means that countries and companies, every time they sell goods, are moving more and more water across the border. But because the water supply of food or clothing or anything else is not allowed in this trade, the water system itself cannot be properly controlled.

As a result, rich countries such as Saudi Arabia and China have begun to buy land in other countries to pay for their lack of clean water. If they can’t find enough water in their limits, the thought goes, why not just put them (included in food) from somewhere? The problem is that the areas that have been purchased are waterless, including sub-Saharan Africa and the Sulfur Springs Valley in southwestern Arizona.

Why Arizona? Because the space is cheap and well connected to the airports, and because there are no water use restrictions.

The United States is the world’s largest exporter of water, according to Robert Glennon, a professor of law at the University of Arizona and one of the country’s leading experts in water law. Glennon calculated that during a recent severe drought, farmers in the Americas used more than 100 billion gallons[100 billion L]of water to grow beans, which were often exported to China.
