This is a most excellent place for technology news and articles.
There's only 70,000 wind turbins, and 58,000,000 cats. Say, do you live in a building with glass?
Uhm.. 2400000000 / 58000000 ~ 41. 234000 / 70000 ~ 3. If we talking about preserving birds I would still address the cat issue before the wind turbine issue.
