There has been the prospect of biofuels causing food shortages, where food crops are replaced with biofuel crops, but there is the fact that biofuel crops like any other need large mounts of water to grow, with associated redirection of drinking water. There is the land required to grow them, and in Indonesia, Malaysia, and no doubt other countries, where forests can face threats, when they are cleared,
to make room for expansion of palm oil plantations. These forests naturally store carbon, and are a key tool in the fight to reduce global warming.

An outbreak of pests and/or diseases could wipe out an entire plantation with one stroke.
Then it will happen.
