These are extracted from atmospheric CO2 by plants algae and certain bacteria using solar energy: this is photosynthesis. The respiration and decomposition of living beings release this CO2 back into the atmosphere.
Wind turbines like many other human activities and buildings also increase the death rate of avian creatures such as birds and bats. A summary of the existing field studies compiled in 2010 from the National Wind Coordinating Collaborative identified fewer than 14 and typically less than four bird deaths per installed megawatt per year but a wider variation in the number of bat deaths. 178
