the ethics of palm oil

I got into this stock after I read a write up somewhere. Mac was involved in the original float at $1 at at 13c in less than a year later, it has to be worth investigating. But I am wondering how those upbeat about this company's future feel about the following:

- UN complaining about food being converted into fuel and bagging biofuels, blaming the process for deprivation of food etc.

- Greens complaining that palm oil plantations are destroying orangutans habitats. Google "palm oil" and this is all that comes up on your first page.

I buy all the stuff about this company being cashed up and on budget re the plant, but is this whole biofuel concept doomed?
