- Aids resistance of trees to disease.
- Reduction of lignin in tree growth.
- Reduces the toxic chemicals used in the paper industry needed to break down lignin.
- Produces trees with increased growth rate.
- Better forest management, which reduces deforestation.
- Trees grown specifically for the paper industry.
- Enzymes break down timber fibres more effectively.
- Paper fibres can be more effectively bonded.
- Recycled paper can be treated more effectively/easily.
- Paper treated to biodegrade more easily and quicker.
- Efficient and faster production.
- Long-term side effects not yet apparent.
- 'Escape' of modified genes into natural ecosystems.
- Development of tolerance to the modified trait by insects or disease organisms.
- Rapid growth could cause shorted, more intensive rotations, resulting in greater water demand and reduced opportunity for nutrient recycling.
