Last weekend, six students from the Donoho School went on a fascinating trip back in
time. These students accompanied Jacksonville State University professor William
Bannister on a fossil hunt. The students, professor, and three graduate assistants headed
to a valley near Cheaha Mountain. The valley was not previously known to have any
fossils in it. However, two months ago, some campers in the valley stumbled upon some
bones sticking out from the ground. When they brought them to the museum, they were
told that the bones were those of a brontosaurus, a species of dinosaur.
Thanks to a generous grant from the Damke Foundation, the students were able to
accompany the professor on his dig. They spent most of both Saturday and Sunday
carefully digging in the area. "We found a few bones," said Wendy Jacobs, a Donoho
senior. "We're not sure which animal they're from, but the professor assured us they were
from a dinosaur."
"The students, all of whom intend to major in science at college, are looking forward to
returning this coming weekend. "There's enough money in the grant for the next month,
so we should get to return at least three more times." said Donoho student Philip Peters.

The National Environmental Policy Act was first presented to Congress in 1969 and the
following year the Environmental Protection Agency (EPA) was established as an
independent agency in the executive branch of the US government "to implement the new
law and permit coordinated and effective government action on behalf of the
environment". The EPA consolidates in a single body the administration of all federal
environmental legislation, ranging from the Refuse Control Act of 1899 to the most
recent statutes concerning environmental pollution. The agency monitors environmental
quality and seeks to control pollution. It has established special programs in air and water
pollution, hazardous wastes, and toxic chemicals, and sponsors research in the
technologies of pollution control. The agency is in charge of collecting environmental
impact statements: reports on the probable environmental effects of proposed projects
which might significantly alter the environment. The National Environmental Policy Act,
which became effective in 1971, requires every US government agency to issue a
statement on any project it plans to undertake, regulate, or fund. From this creation to the
present day, the environmental impact statement has been attacked as a hindrance to
economic growth and as too vague to prove a strict standard for environmental control.
The EPA reviews all federal environmental impact statements to ensure that the
statements comply with laws. Litigation may be instigated if environmental
considerations conflict with existing zoning or planning laws. The Endangered Species
Act of 1972, which is designed to protect rare animal and plant species, has been used to
block several projects that might destroy vital wildlife habitats.
