Human Activties and Greenhouse Gases
We discuss the concept that carbon dioxide released from the burning of fossil fuels is partly responsible for the current atmospheric carbon overload. We also briefly discuss other human activities that contribute to the atmospheric carbon overload.
This Friday, Beijing will show off its green improvements when the Olympics begin.
An introduction to Richard Hilderbrand’s new blog discussing climate change, plus the first installment. Learn how Earth utilizes greenhouse gases to ensure stable temperatures, or thermal equilibrium, as well as how fluctuations in solar activity relate to changes in global temperatures.
For the first time since the U.S. Energy Information Administration began collecting data on greenhouse gas emissions in 1990, the United States saw a record-setting 5.8 percent decline.
A new study finds that warming temperatures will cause up to two-thirds of the earth's permafrost to disappear by 2200, unleashing large amounts of carbon dioxide into the atmosphere.

The invention of clear window glass allowed the ancient Romans to trap solar energy to enhance their gardening techniques to grow vegetables out of season and exotic non-native plants in Rome. A thousand years later, empire builders in Europe rediscovered the trapping of solar heat with clear window glass so they as well could enjoy the foreign plants in their own back yard and grow native vegetables throughout the year.

We’re here to confront our own biology, the essential nature that tells us to keep reproducing and expanding. If you could view the entirety of human experience from the dawn of our evolution to the present, if you could pick the human century you’d like to witness first-hand, you might choose this one.
While conservation is neccessary for providing for an ever-growing human population, it alone cannot solve our problems. In fact, it may distract us from the real issue at hand.
But it’s not our nature to sit around complacently waiting for the asteroid, not while we have this miraculous opportunity to preserve and enhance our planet. Just as we once visualized the first irrigated field, invented the first wheel and dreamed of machines that fly, we can visualize the earth as a beautiful and productive garden where millions of species thrive. Then we can build it.

The role of natural cycles and anthropogenic forces on the climate are explained. We also demonstrate that the current global warming trend is happening at a faster rate than earlier periods and humans are responsible for the current warming trend.
Many farms of the 21st Century are, comparatively speaking, biological wastelands. Plowed, fertilized and cultivated from property-line to property-line, much of the world’s most productive land has been stripped of its wildlife.
Our innovations have made possible a rapid expansion in the quantity of human life on earth. But the same technological foundation is used, with equal facility, to improve and sustain the quality of human life.
Environmentalists should strive to understand the joy experienced by the race fan, the motorcyclist and the snowmobiler, and we should use that understanding to stimulate the human imagination in ways that benefit the planet.
Human history gives us plenty of evidence to support a pessimistic outlook, but history also gives us plenty of reason for optimism. On the humble foundation of skin clothing and bone jewelry we have built a wondrous technological superstructure.
An alien biologist visiting from a distant planet might look at the remarkable similarities in our physiology and conclude that chimps would live pretty much as humans do, only more simply. But there’s something definitively, well, human about us.
Environmentalists are better leaders when we can better love human ingenuity. We will need to form partnerships with the natural world, to ingeniously utilize its resources in ways that preserve its natural productivity.
Most people have at least heard of Habitat for Humanity. But when I dug a little deeper and sifted through the ol’ letters in the attic of the house (so to speak), I uncovered some interesting details.

Food is the most universal symbol of America’s age of excess. The average American’s dinner comes from five different countries, with a combined airfreight and ocean freight mileage tab that often exceeds 10,000 miles. At least three-fourths of that meal is processed and packaged, its nutrients stripped away and replaced by texturizers, sweeteners, and flavor “enhancers.”
We are unique and brilliant creatures. Humanity has expanded into every corner of the planet. With our extraordinary tools, we are stronger and faster than any other species. And we are improving.

We don’t have a positive vision for our future, but we can picture a lot of different ways in which things may go badly for us. This lack of a positive vision seems dangerous to me because we so often realize what what we visualize.
Today as I was researching Habitat for Humanity, I learned how far its helping hand reaches. Even more interesting to me, though, was that Habitat continues to build in such war-torn counties as Afghanistan and Pakistan.
Gardening for the first time ever in a hoophouse is a lot like gardening elsewhere. But, it is gardening in a whole different climate!

“Do you sometimes feel like your life is a microfield for everything that’s going on today?” scholar, philosopher and researcher Dr. Jean Houston, one of the foremost visionary thinkers and doers of our time and a founder of the Human Potential Movement, asked the crowd gathered this morning for the LOHAS Forum in Boulder, Colorado. That got my attention, especially when she went on to say that humans now face “the most profound task in human history—choosing whether we grow or whether we die.”
At this moment, Houston says, many of us are “encapsulated bags of skin carrying around dreary little egos,” caught up in “lives of serial monotony.” Still, she has hope. Humans, she said, have an opportunity to play a role in “the greatest transition the world has ever seen, the most far-reaching and rapid change in our history.”
“We are coded with potentials, few of which we ever learn to use,” Houston said. “We can no longer be half-life versions of ourselves, and something huge is beginning to happen as the world’s mind is discovering itself.”

Ode to our hand saw...why we choose to live without power, and what we've accomplished by hand.
On our journey to self-reliance, my husband, Darren, and I have been gathering human-powered tools when we can find them. It’s surprising and sad how quickly hand- and foot-powered tools were junked when electricity became available. From 1850 to 1890, more than 100 apple-pealing devices were patented. Then none, except those running on electric power. And so it goes with thousands of other nifty human-powered appliances.
