National parks are "America's best idea," filmmaker Ken Burns says in his new PBS documentary. He talks to NRDC's OnEarth magazine about the tragedy of wolf hunts, the need for wilderness preservation and the threat of global warming.
The National Parks film by Ken Burns has been spectacular so far. Tune in and you will be inspired by the stories of dedicated individuals who campaigned to preserve some of the most extraordinary wild places in our country.
The library has an enormous amount of material devoted to the national parks; just search national parks and reserve as a subject heading in OBIS to get started. Virtually explore any national park at the National Park Service web site.

From their web site:"Since 1990, Environment Ohio staff have filed 12 lawsuits under the Clean Water Act, forcing illegal polluters to pay over $2 million in fines. In a landmark case, Wheeling-Pittsburgh Steel paid $700,000 for polluting the Ohio River." Read more.
Learn more about water pollution in Ohio from library materials found with a subject search in OBIS on "water pollution ohio", including this Scientific Investigations report from the U.S. Geological Survey:

Oil Rig of the Future: A Solar Panel That Produces Oil
Researchers propose a novel approach to producing biofuel using diatoms
By Saswato R. Das
a brief excerpt:
"Scientific analysis of diatom oil has shown that it is very suitable for use as biofuel, says T. V. Ramachandra, a professor of ecological sciences at the Indian Institute of Science (IISc) who is working on this project with IISc researchers Durga Mahapatra and Karthick Balasubramanian, along with Richard Gordon, a radiology professor at the University of Manitoba in Winnepeg.
[Rmachandra says,] "The oil can be as much as a quarter of the total mass of a diatom cell, and if a way could be found to efficiently wrest it from diatoms, he adds, a hectare of "diatom cultivation could produce 10 to up to 200 times the oil that is produced by soybean cultivation."
Read the article and many comments that express both skepticism and support, at the Scientific American web site.
Want more information on algae as a biofuel? Search:
(algae or algal or diatom*) and biofuel*
in ISI Web of Knowledge (from an OhioLINK library). Over 70 references result, including a number of articles in oil trade publications and business sources as well as technical papers on algae bioengineering.
The library has many books on biofuels, including some ebooks:
Biofuels, solar and wind as renewable energy systems: benefits and risks / David Pimentel, editor. Springer, 2008.
Biofuels for road transport: a seed to wheel perspective / Lucas Reijnders, Mark A.J. Huijbregts. Springer, 2009.
These books, published by Springer, are accessible electronically from any OhioLINK library on the OhioLINK EBook Center. They can also be accessed by OhioLINK members at SpringerLink.com.

Here is a snippet of the conversation, considering the difficulty faced by people on limited incomes who want to eat healthy food.
Pollan - "You can get 1,250 calories per dollar of chips or cookies but only 250 calories of carrots or broccoli. Um, that is due to the fact that the farm policies we have are favoring the really unhealthy calories. We subsidize corn and soy, which are really the building blocks of fast food. We subsidize feedlot meat, we do a lot to ensure that fast food is cheap. So, I think the personal responsibility argument breaks down pretty quickly and I think you really need to look at the environment in which we're eating and the system that is dictating the choices that we supposedly have."

Listen to the episode, and hear Ms. Goodall discuss the essential roles played by organisms of all types and sizes, the vast number of species in danger of extinction before they are even described or understood, and our dependency on biodiversity for maintaining healthy ecosystems that support human as well as other forms of life. A copy of Goodall's new book is on its way to the Science Library:
Hope for animals and their world : how endangered species are being rescued from the brink / Jane Goodall, with Thane Maynard and Gail Hudson.
