One planet - one people
The theme for Human Rights Day 10 December 2010 is human rights defenders who act to end discrimination.
Human rights defenders acting against discrimination, often at great personal risk to both themselves and their families, are being recognized and acclaimed on this day.
Human rights defenders speak out against abuse and violations including discrimination, exclusion, oppression and violence. They advocate justice and seek to protect the victims of human rights violations. They demand accountability for perpetrators and transparency in government action. In so doing, they are often putting at risk their own safety, and that of their families.
Some human rights defenders are famous, but most are not. They are active in every part of the world, working alone and in groups, in local communities, in national politics and internationally.
Human Rights Day 2010 will highlight and promote the achievements of human rights defenders and it will again emphasize the primary responsibility Governments have to enable and protect their role. The Day is also intended to inspire a new generation of defenders to speak up and take action to end discrimination in all of its forms whenever and wherever it is manifested.
The story does not end after 10 December 2010. The focus on the work of human rights defenders will continue through all of 2011. (read more)

E. L. E.
The clathrate gun hypothesis is the popular name given to the hypothesis that rises in sea temperatures (and/or falls in sea level) can trigger the sudden release of methane from methane clathrate compounds buried in seabeds and permafrost which, because the methane itself is a powerful greenhouse gas, leads to further temperature rise and further methane clathrate destabilization – in effect initiating a runaway process as irreversible, once started, as the firing of a gun.
The sudden release of large amounts of natural gas from methane clathrate deposits in runaway climate change could be a cause of past, future, and present climate changes. The release of this trapped methane is a potential major outcome of a rise in temperature; it is thought that this is a main factor in the global warming of 6°C that happened during the end-Permian extinction, as methane is much more powerful as a greenhouse gas than carbon dioxide (despite its atmospheric lifetime of around 12 years, it has a global warming potential of 62 over 20 years and 23 over 100 years). The theory also predicts this will greatly affect available oxygen content of the atmosphere.
The consequences of a methane-driven oceanic eruption for marine and terrestrial life are likely to be catastrophic. Figuratively speaking, the erupting region "boils over," ejecting a large amount of methane and other gases (e.g., CO2, H2S) into the atmosphere, and flooding large areas of land. Whereas pure methane is lighter than air, methane loaded with water droplets is much heavier, and thus spreads over the land, mixing with air in the process (and losing water as rain). The air-methane mixture is explosive at methane concentrations between 5% and 15%; as such mixtures form in different locations near the ground and are ignited by lightning, explosions and conflagrations destroy most of the terrestrial life, and also produce great amounts of smoke and of carbon dioxide. Firestorms carry smoke and dust into the upper atmosphere, where they may remain for several years; the resulting darkness and global cooling may provide an additional kill mechanism. Conversely, carbon dioxide and the remaining methane create the greenhouse effect, which may lead to global warming. The outcome of the competition between the cooling and the warming tendencies is difficult to predict. (read more)

Today Is Earth Day: It's A Question of Survival
Earth Day is a day designed to inspire awareness and appreciation for the Earth's environment. It was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970 and is celebrated in many countries every year.
John McConnell first introduced the idea of a global holiday called "Earth Day" at the 1969 UNESCO Conference on the Environment. The first Earth Day proclamation was issued by San Francisco Mayor Joseph Alioto on March 21, 1970. Celebrations were held in various cities, such as San Francisco and in Davis, California with a multi-day street party. UN Secretary-General U Thant supported McConnell's global initiative to celebrate this annual event; and on February 26, 1971, he signed a proclamation to that effect, saying:
"May there be only peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it continues to spin and circle in frigid space with its warm and fragile cargo of animate life."
John McConnell's concern for the environment grew in the late 1960s and early 1970s. He became moved when he saw the first picture of the Earth printed in Life magazine. Later that picture became the symbol on the Earth Day flag in which he designed and created. The Earth Day Flag was featured in "Whole Earth Catalogue" and was used, here and there around the world, to show support of efforts to help people and planet. The Earth Day Flag is a symbol of Earth Day and is still part of the Earth Day Ceremony each year at the United Nations.
On 22 April 1970, Earth Day marked the beginning of the modern environmental movement. Approximately 20 million Americans participated. Thousands of colleges and universities organized protests against the deterioration of the environment. Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, Freeway and expressway revolts, the loss of wilderness, and the extinction of wildlife suddenly realized they shared common values.
As Senator Nelson attests, the most impressive thing about this movement was how it had no central governing body and simply grew on its own:
"Earth Day worked because of the spontaneous response at the grassroots level. We had neither the time nor resources to organize 20 million demonstrators and the thousands of schools and local communities that participated. That was the remarkable thing about Earth Day...it organized itself." (read more)

The Medicine of Altruism
Altruism: unselfish interest in the welfare of others.
"In Tibet we say that many illness can be cured by the one medicine of love and compassion. These qualities are the ultimate source of human happiness, and need for them lies at the very core of our being. Unfortunately, love and compassion have been omitted from too many spheres of social interaction for too long. Usually confined to family and home, their practice in public life is considered impractical, even naive. This is tragic. In my view point, the practice of compassion is not just a symptom of unrealistic idealism but the most effective way to pursue the best interest of others as well as our own. The more we- as a nation, a group or as individuals - depend upon others, the more it is in our own best interests to ensure their well-being."
"Practicing altruism is the real source of compromise and cooperation; merely recognizing our need for harmony is not enough. A mind committed to compassion is like an overflowing reservoir - a constant source of energy, determination and kindness. This is like a seed; when cultivated, gives rise to many other good qualities, such as forgiveness, tolerance, inner strength and the confidence to overcome fear and insecurity. The compassionate mind is like an elixir; it is capable of transforming bad situation into beneficial ones. Therefore, we should not limit our expressions of love and compassion to our family and friends. Nor is the compassion only the responsibility of clergy, health care and social workers. It is the necessary business of every part of the human community."

Junk Yard Man
You are not content with
polluting your planet
Now you have made your
outer space a junk yard too
Within the vast debris field
there are tens of millions of
small fragments and an estimated
19,000 at 1 kilogram (2.2 lb) or heavier
The Kessler Syndrome will soon render
space exploration, and even the use of
satellites, infeasible for many generations

The Chemical Edge
This little piggy went to market,
This little piggy stayed at home,
This little piggy had roast beef,
This little piggy had none...
And this little piggy is an example
of what chemical and toxic pollution
is doing to biological life forms,
meaning us, the cause of it all,
we are the little guinea piggies,
and we will be the ones that go...
"Wee wee wee" all the way home.
