Australia is about to embark on an adventure in offshore wind farms, with the first two offshore wind energy zones declared in Bass Strait. While wind energy will play a huge role in reducing Australia's greenhouse gas emissions and combatting climate change, those giant propellers in the sky also pose their own risks to marine life, particularly birds.

Ecologist Keith Reid earlier this year published the first assessment on the risks that offshore wind farms pose Australia's birds. In this episode, we find out what happens when birds and wind farms meet, and how to weigh the risks. Read Keith's research online.
