Global worming/Insect light pollution

Earthworms, which are beneficial to the soil in some areas, are now heading into places like the northern forests of Canada and the U.S. - disturbing the soil and transforming ecosystems. It could result in large amounts of carbon stored in the ground to be released into the atmosphere. Dr. Justine Lejoly is one of the researchers with the University of Alberta who’s been looking into the phenomenon of ‘global worming.'

Even though we might take them for granted, healthy insect populations are critical for life on earth. We hear about insects dying off because of pesticides, climate change, or other causes we don’t yet understand.  One factor is light pollution - that is artificial light from homes and buildings. Dr. James Karl Fischer is the Executive Director of the Zoological Lighting Institute.
