Technology is a double-edged sword.
Technology is both the cause of many environmental problems and also a key to solving them. Combustion of fossil fuels causes CO 2 emissions while solar cells might offer ways of obtaining cleaner energy. The cars of the 1930s consumed less fuel per kilometre than the average car of today. The reason of course is that other characteristics, e.g., acceleration, speed, safety and comfort, have been considered more important than fuel efficiency. Whether technology will bring us closer or farther away from environmental sustainability depends on the path technological development takes.
