Birds as Environmental Indicators
Humans have invented a variety of instruments to monitor the health of ecosystems. For example, to examine water quality in a wetland, an environmental scientist may use a sensor to measure dissolved oxygen in the water or perform chemical assays in the lab to examine heavy metals in the soil. However, in some cases we…

Indoor Air Quality and Environmental Health
It is estimated that people spend up to 90% of their time indoors. (1) As such, indoor air quality can have an immense impact on health and general quality of life. Both the Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) provide guidance based on research for indoor air quality but it…

Solar Power 101: Advantages & Disadvantages
Solar power is the conversion of the sun’s energy into electricity. With an estimated 173,000 terawatts of solar energy continuously hitting Earth’s surface (1), there is more than enough energy to meet the world’s current consumption levels of 15 terawatts per year (2). The trick, though, is collecting it. Solar Power Technology Solar energy is primarily collected…
