Why Forest Biotechnology ?
Swedish exports and imports of some product groups 2004 Billion SEK 0 40 80 120 160 Forest industry products Cars, car parts Electronic goods,computers Other engineering products Energy goods Iron-ore, iron and steel Pharmaceutical products Exports Other chemical products Imports Dramatically increased pressure on forest production due to: Increase in world’s population (+ 3-4 billion people). These people need wood for heating, paper and construction materials. Conversion from a society based on fossil fuels to a society based on energy and materials derived from renewable sources: wood fibers. Big challenge for forest industry that needs to secure its supply of wood for pulp and paper and construction materials
