Palm oil gets a bad rap from what I can tell. Most of the crops that have the biggest impact, such as palm oil, do so because they're the most used. However, they're often the most used because they're the most efficient. Dropping palm oil may have consequences if you just shift your oil use to a less efficient crop. Now you need even more farm land!

In the end the best general answer to TheAverageBiologist is to consume less and get involved in politics.
