Fresh water stats

Here in the West most people are well aware of the limited water supply.  However, most Americans live in fairly wet areas and probably never give a second thought to the water they drink, shower in, and more importantly flush down the toilet.

I thought I'd list some quick facts about America's mind boggling water usage[1]

  • If all the world's drinking water were put in one cubical tank, the tank would measure only 95 miles on each side.
  • Number of people currently lacking access to clean drinking water: 1.2 billion.
  • Percent of the world's households that must fetch water from outside their homes: 67
  • Percent increase in the world's population by the middle of the 21st century: 100
  • Percent increase in the world's drinking water supplies by the middle of the 21st century: 0
  • Amount of water Americans use every day: 340 billion gallons.
  • Number of gallons of water needed to produce a car: 100,000
  • Number of cars produced every year: 50 million.
  • Amount of water required by a nuclear reactor every year: 1.9 cubic miles.
  • Amount of water used by nuclear reactors every year: the equivalent of one and a third Lake Eries.

So all this to say, clean water is a precious resource, let's start treating it like one.

Watering the Desert

Saturday, August 22nd, 2009

About 1/3 of the earth's land surface is desert (<10 inches of rain per year).  With such a lack of water life is,  to say the least, difficult.

But as usual a few dreamers have developed a highly plausible solution.

Greenhouses usually provide warm growing conditions in cooler climates. But why not use the idea in reverse to make growing crops possible in inhospitably hot climates?

This "reverse" greenhouse is designed to create an environment that is cool, humid and bright, a reverse of the warming effect of typical cold climate greenhouses. It is for use in desert climates adjacent to seawater. First, you have to find a desert next to the sea, which is not too difficult, actually.

With a setup like this one could not only grow crops in the desert but create usable drinking water as well. I wonder if this could work here in Colorado?

and we're back...

It's been a few weeks since last greentheo had something to post.  Yep... been kind of busy working  in the garden.  So far I've had all the lettuce come in along with the Spinach.. so delicious.  The peas are forming their little pods, the squash are flowering and starting to form their little bulbous fruits, and the green beans are climbing the mammoth sunflowers as hoped.

But perhaps most importantly, Christmas has come early this year.  Colorado now allows rain harvesting!

Finally, my law breaking lifestyle has come to an end and I can legally use the water collected from my roof.

I bet grey-water systems will be up next for review.

Happy Gardening and summer fun to you all!

What about the poor people?

Tuesday, October 21st, 2008

With all this talk between Obama and McCain about the middle class of America, Main Street and other such euphamisms for those doing decently well in America, there's almost no talk about the working and non-working poor.

It's absolutely baffling that in the wealthiest country in the world:

33 million Americans continue to live in households that did not have an adequate supply of food. Nearly one-third of these households contain adults or children who went hungry at some point in 2000.

In the face of our homegrown poverty we spend about $700 billion on the department of defense and another $250 billion per year on interest on our national debt.

There's also no talk about some of our country's imminent resource and infrastructure crisises... and not just oil... water, sewage, highway, rail, dams, forests (here in CO we're losing millions of acres of forest to the Japanese pine beetle... a problem which might have been solved by a few more forestry dollars).

And still, neither candidate will even begin to mention that it's not main street, or wall street that needs help, it's Martin Luther King Blvd that needs help.

It's not because they're opposed to handouts either, they just gave Wall Street a $700 billion blank check to fix their mistakes (both McCain and Obama voted yes to the porky bailout).

Hmm... grace for the rich but the heavy hand of "you should have tried harder" for the poor? Not on my watch.

Luckily there is a candidate who does see these problems and is willing to try and fix them if we give him a shot.
