The observation of nature and the formulation of a hypothesis is the back bone of many scientific experiments today. This allows for many observers or scientists to product a conclusion based on statistical results of the phenomenal (SOURCE). The result of the scientific method has produced much technological advancement and has solved many practical problems (Bocking, 2006). Many inventions by science has given power to scientist and their work, this “authority of science” as Bocking (2006) describes it, allows power to reside in science and allows for it to be trustworthy enough to be part of many political decisions. This authority has placed a status on science as a provider of reliable knowledge (Bocking, 2006). In many …show more content…
If one were to look at human related variables, then the third most bird related mortality variable would be transmission line collisions, which is responsible for more than 16 million bird deaths (Calvert et al, 2013). The article by Calvert et al (2013) suggests that there are other variables that contribute higher bird mortality than wind power. The article by Pagel et al (2003) is a collection of reports by industry on bird death by wind turbines, while the article by Calvert (2013) is an estimation based on reports. Both support either sides of the argument, thus causing more controversy.
Since the wind industry acknowledges that wind turbines have the potential to harm or cause bird mortality, the industry has put in resources to resolve this issue. Collaboration between TansAlta Corp. and the University of Calgary have found a way to reduce bat mortality by 60% (Jones, 2013). They were able to achieve this by studying the interactions between bats and wind turbines. They found that bat mortality were not the result of external injury, but by lung damaged through a drop in air pressure (Jones, 2013). The drop in air pressure was caused by the low rotation frequency of the turbine blades (Baewald et al, 2008; Jones, 2013). This finding has been supported by other research papers such as the one by Baewald et al (2008) Barotrauma is a significant cause of bat fatalities at wind turbines. Their findings were that 8% of bats had only external
