I'm guessing that you're too young to remember. Lucky 10000! In the 1990s, McDonald's was under attack for a variety of anti-environmentalist practices, and by 2001 there was a class-action lawsuit against them for using beef tallow in fries from a coalition of vegetarians, vegans, and primarily Hindus who were deeply offended that they had been tricked into consuming what they consider to be a sacred animal. In a nutshell, it's a very racist and revanchist move, not just an anti-environmentalist move.

Unlike normal, I can't link to good peer-reviewed articles on the topic. McDonald's is one of the few groups who can successfully control their Internet presence, and they've washed away these controversies as best they can. I almost feel like linking to this summary of the case on Wikipedia is unhelpful, since it's got so many apologetic caveats. They do this all over Wikipedia; McLibel or Liebeck are also heavily edited in favor of McDonald's. You'll have to explicitly add "hindu" or "indian" to search queries; for example, instead of "mcdonalds beef tallow", try "mcdonalds beef tallow hindu indians".
