Maintaining a Balance in Natural Areas

  • Martin Smay on his horse Golden Feather likes to ride in public parks. He says there has to be balance between recreational uses and preservation.

Whether it’s hiking, biking, or riding all-terrain vehicles… every time
you use a park, you damage it. It’s the job of park managers to balance the
recreational uses against preserving natural areas. It’s not easy. The
Great Lakes Radio Consortium’s Lester Graham reports… people want more
places for new types of recreation, but park managers are still struggling
to find the right balance for more traditional recreational activities:

New Threats to Indoor Air Quality

Consumers are becoming more aware of indoor air quality problems that can be
caused by emissions from materials like particle board, paint and carpeting.
But a new report identifies more threats. The study found that household
appliances like dishwashers, washing machines and shower heads can release
chemicals from the water into the air…and add to the air pollution inside
your home. The Great Lakes Radio Consortium’s Wendy Nelson reports:

A Revolution Among Plant Scientists

Scientists are discovering new genetic information about plants is
upsetting the natural order of things. The Great Lakes Radio
Consortium’s Lester Graham reports that they’re also finding a whole new
world of possibilities for using plants for medicines and products:

U-V Light May Be Viral Catalyst

Ultraviolet light, which some scientists say may be the culprit behind
the Great Lake’s epidemic of mutated frogs, is now part of an
investigation into a smaller but equally important part of the
environmental web. Scientists in Duluth are looking into the viruses
that infect bacteria in the Great Lakes, and how increasing amounts of
U-V light might affect that relationship. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:

Genetically Altered Trees Eat Mercury

In an article in the journal "Nature Biotechnology" researchers saythey’re developing plants that clean up mercury contamination. TheGreat Lakes Radio Consortium’s Lester Graham reports:
