Though relatively few people know it by name, palm oil is found in over fifty per cent of processed supermarket goods, from soaps to snacks. This vegetable oil, which is taken from the fruit of the oil palm tree, causes a great deal of environmental concern. The clearing of tropical forests to grow oil palm plantations threatens the survival of orangutans and other endangered species. The land conversion often happens on carbon rich peat soils in a process which releases significant greenhouse gas emissions. Yet even some environmental organisations warn that alternative vegetable oil crops may require much larger areas of forest to be converted to agricultural land.
Which one of the following is a conclusion that can be drawn from the above passage?
A. A ban on palm oil alone would not solve all of the environmental problems associated with vegetable oil production.
B. If farmers stopped clearing tropical forests for oil palm plantations, endangered orangutan populations would recover.
C. The environmental risks associated with oil palm plantations are not well understood in tropical countries.
D. To produce the most profitable crops, oil palm plantations must be grown on carbon rich peat soils.
E. There is no motivation for manufacturers to stop using palm oil in their products.
