Radiation Monitoring on the Nevada Test Site
Beginning in the 1950s, Reynolds Electrical & Engineering Company conducted radiation monitoring for test-related activities and later added routine environmental surveillance of air soil, vegetation, surface water, and wells. The University of California, Los Angeles, and several other western universities conducted detailed investigations of radiation effects on desert ecosystems. In 1970, the Nevada Applied Ecology Group started investigating the environmental impact of plutonium and other transuranics scattered in soil by "broken arrow" and other warhead safety tests. The 15-year investigation focused on the mobility and uptake of transuranics into the food chain
Radiation Monitoring For Underground Tests
Conducting nuclear tests underground greatly reduced the amount of radioactivity released into the atmosphere. Test-specific radiation detectors arrayed around surface ground zero supplemented the permanent remote area monitoring system and offsite monitors. If a release occurred, air support responded immediately to track the effluent and assist in determining its composition, intensity, and course. With the exception of a few Plowshare excavation experiments during the 1960s, and Baneberry in 1970, there were no releases of particulates that resulted in radioactive fallout offsite after testing went underground. Most offsite releases consisted of small concentrations of very short-lived radioactive xenon, a chemically inert noble gas.

I photographed this little Burrowing Owl on the "dredge spoils" (area a) of the Ballona Wetlands in Marina Del Rey of coastal Los Angeles. Burrowing Owls are rare now on the Ballona Ecosystem where they were once common. The Ballona Wetlands are the last remaining coastal wetland in Los Angeles.and a treasure to be protected
Since taking this photo I've learned that there hasn't been a photo of a Burrowing Owl at Ballona since the 80's.
Update 1-7-06 - The Burrowing Owl continues at the Ballona Wetlands where apparently it has decided to spend the winter. I have been viewing it for over a month as it stands on a mound near one of the salt marsh distributaries.
Update 2-18-06- The Burrowing Owl continues at the Ballona Wetlands.
Update The previous February 18 date was the last time I viewed the Burrowing Owl on the Ballona Wetlands since first sighting the little Owl 113 days earlier on October 29, 2005. Since then a red fox was seen sleeping on top of the burrow the Burrowing Owl had occupied and since then it appears ground squirrels were also occupying the burrow. A Burrowing Owl was seen recently twice near the west end of LAX at the edge of Playa Del Rey on the coastal side.

Language not only communicates, it defines culture, nature, history, humanity, and ancestry. The indigenous languages of the Arctic have been formed and shaped in close contact with their environment. They are a valuable source of information and a wealth of knowledge on human interactions with nature is encoded in these languages. If a language is lost, a world is lost. This deep knowledge and interconnectedness is expressed in Arctic song, subsistence practices, and other cultural expressions but especially in place names across the Arctic. Place names of the indigenous peoples reflect subsistence practices, stories, dwelling sites, spawning sites, migratory routes of animals, and links to the sacred realms of the indigenous peoples of the north. This map presents the original languages of the respective indigenous peoples, even if they do not speak their languages today. Notes: Overlapping populations are not shown. The map does not claim to show exact boundaries between the individual language groups. Typical colonial populations, which are not traditional Arctic populations, are not shown (Danes in Greenland, Russians in the Russian Federation, non-native Americans in North America).

To live on the moon, you would need an atmosphere. On Earth the atmosphere is generated very largely by living organisms. To survive in your new atmosphere, you would have to take with you rather a lot of stuff that nature supplies here on Earth. Although many humans live in great luxury, more or less disconnected with the living world in their own perceptions, almost all of their well-being depends on goods and services delivered by things that live.
Everything we eat, for example, was recently nourished by ecosystems in the soil. These days the work of those soil organisms is often supplemented or disrupted by products synthesised from oil - another product of ecosystems, albeit ecosystems that lived some 360 million years ago. Cotton, wool, timber, and many pharmaceuticals are the product of the living world.
In 1981 Paul and Anne Ehrlich coined the term “ecosystem service” to refer to these things that humans get from the living world. A decade later the Millennium Ecosystem Assessment categorised the services into “provisioning” services such as food and fibre; “regulating” services such as control of climate, floods or disease; “cultural” services such as spiritual, cognitive, aesthetic and cultural benefits; and “supporting services” such as production of atmospheric oxygen, soil formation, and nutrient cycling, that themselves maintain the conditions for life on Earth.
This picture illustrates one of the more depressing findings of the Millennium Ecosystem Assessment, or MA; most of the ecosystems on Earth have been and continue to be degraded. The culprit, in every case, is the human species, either directly or indirectly. There are so many of us, and we demand so much from the planet, that ecosystem services are increasingly disrupted.
Among the out of focus tiles you will see “food” and “water”, and several other services that are missing letters here and there.
Cheshire Wildlife Trust - "Formed by glaciers retreating after the last ice age, the meres and mosses are a chain of bogs, marsh and fen wetlands of international importance, spilling out from Cheshire into Shropshire, Staffordshire and parts of north Wales. While only a fragment of their former size, they are still home to many plants and insects that are rarely found elsewhere."

Within industrial countries, the area burned by fires is declining but the number of major fires is increasing. In the United States, for example, the area burned has declined by more than 90% since 1930, while in Sweden the area burned annually fell from about 12,000 hectares in 1876 to about 400 hectares in 1989.

Notice - SKAM does not endorse the killing of oneself or others. SKAM endorses an open communication about the damage humans have done to our planet.
The Recycle Yourself Project is meant to invoke an emotion and discussion about such issues as Overpopulation, Pollution, Ecosystem Destruction Humans responsibility to the Environment, Culture Jamming, Art intervention and Anti-Commercialism/over-consumption.
The Recycle Yourself Philosophy
For billions of years the earth has recycled the life that has existed on it. Through a natural cycle. At one time the Human race followed that natural cycle. The humans lived hand and hand with the environment taking and giving back to the land. Even after death humans at one time gave their actual bodies back to the planet to decay in a natural way. Over time mankind has forgotten about our beautiful planet and how it created the life that exists on it. Then comes the age of the industrial revolution and corporations built upon mass consumerism. Marketing companies assault us ever day. By the time you are 5 years old you've already had 200,000 images planted into your brain from television and ad campaigns. This false reality is built and constructed into our minds to appear that if its sold on tv there is an unlimited supply. Buy buy buy this constructed ads tell us that there is nothing wrong with this behavior. The status quo is a false reality.
The real reality
Humans have already started what will be known as the 6th mass extinction on our planet. This has been created by the abuse we've done in the last 300 years to our mother earth. The western mindset has infected the entire planet. Kill, rape and pillage, give nothing back. Even in death humans turn themselves in plastic wrapped corspe's that seep poisons into the ground that in turn effect our drinking water. Cancer, disease, and viruses are a by-product of our planet trying to control this over consumerism culture. Mother earth will win this war in the end but it will be at the expense of all forms of life on our planet. Education is the only thing that will change this behavior. If you want to climb the mountain you don't just jump to the top. This change needs to happen in steps. The first is being aware of such steps. If humans so selfishly ignore these warning signs. Some day there will be no fish in the sea, no birds in the sky, no whales in the ocean, no dogs to follow their masters, no flowers to bloom, no bees to pollinate them. This is a reality.
Now you have to ask yourself?
Do you want to be responsible for a dead planet?
Educate
Reduce
Reuse
Recycle Yourself!

On my forays to the St. Andrews Jetties, I almost always stop to take a look at the marsh, or Gator Lake.
You might catch an egret or heron prowling up close, a Whitetail browsing out there, or a glimpse at a passing osprey.
Since it's right off the road, you can't help but draw attention from passing vehicles, and of course, everyone wants to know what you're looking at. No one seems to believe anyone would just take a picture of the marsh itself... there must be a creature in there somewhere.
Apparently, also, if you're standing next to a camera in this area, that indicates to people that they should come up to you and ask how to differentiate between an Osprey and an Ostrich (because they always get those two confused) and inquire about where all the gators are at any given time.
This is another reason why it's best to visit early in the morning or late in the afternoon.
