Take a look at www.palmoiltruthfoundation.com. It's a site that shows that palm oil cultivation does not necessarily lead to the destruction of rainforests. For one thing, cultivation is usually on designated agricultural land. Also, there is a roundtable on sustainable palm oil for the various stakeholders in the palm oil industry.
I even saw a video of how plantation workers are trained to treat and heal injured orang utans should they come across them!
It is true that some illegal logging is being done, but it is not only for palm oil. They also use the burning technique for clearing land for grain or do timber logging, again, all illegal. The important thing is that the palm oil industry should not be 'blacklisted' or accused of something they may not even be responsible for but for a few bad apples!
