Dangers of Asbestos Although asbestos is a natural mineral, it is not safe for humans. Exposure to asbestos can harm the human body, causing serious and even fatal illnesses in many people. These often deadly illnesses include the aggressive type of cancer called mesothelioma. Also see The International Agency for Research on Cancer (IARC) classifies all forms of asbestos as group 1 carcinogens.

Darwin's Predictions or if a broken link, click here.


This is from Nova's "Intelligent Design on Trial", produced by PBS. In 2005, parents took the Dover School Board in Pennsylvania to court as the board attempted to pass off a religious view as science. The court not only defended the constitution's  First Amendment, but it also revealed that there is a great deal of experimental evidence for evolution and that proponents of biology's most important theory are not necessarily atheists. In this specific piece, evidence is presented for many of Dawrin's predictions that have led us to realize that all life forms have a great deal in common, more specifically, about 500 genes.

No Sun Link' to Climate Change


A new scientific study(2007) concludes that changes in the Sun's output cannot be causing modern-day climate change.

It shows that for the last 20 years, the Sun's output has declined, yet temperatures on Earth have risen.

Tsunami Facts

Historically, tsunamis have ravaged the Hawaiian islands. In fact 13 have struck between 1900 and 1965.

In early October, 1996, the ozone hole in Antarctica peaked at a record 7.7 million square miles. (Source: U.N. weather agency) There is also ozone depletion in the Arctic and in the rest of the world. Interestingly, each region's atmospheric idiosyncrasies lead to different breakdown rates. This EPA site answers basic questions and, as well, provides links for the more serious surfer.

The Gaia Hypothesis

"You may find it hard to swallow the notion that anything as large and apparently inanimate as the Earth is alive. Surely, you may say, the Earth is almost wholly rock, and nearly all incandescent with heat. The difficulty can be lessened if you let the image of a giant redwood tree enter your mind.The tree undoubtedly is alive, yet 99% of it is dead.The great tree is an ancient spire of dead wood, made of lignin and cellulose by the ancestors of the thin layer of living cells which constitute its bark. How like the Earth, and more so when we realize that many of the atoms of the rocks far down into the magma were once part of the ancestral life of which we all have come."
-James Lovelock
Also read one of his favorite examples of how the earth's physical and biological realms are deeply integrated, creating the illusion that the planet itself is alive, acting as a giant organism with a variety of self-regulating systems.
