20 Top Predictions for Life 100 years from Now

Although predictions about the future are fun to read, their record for accuracy is generally pretty poor.

Last week we asked readers for their predictions of life in 100 years time. Inspired by ten 100-year predictions made by American civil engineer John Elfreth Watkins in 1900, many of you wrote in with your vision of the world in 2112.

PT: Good chance. According to Dennis Bushnell, chief scientist at the Nasa Langley Research Center, saltwater algae that's been genetically modified to absorb more nitrogen from the air than conventional algae could free up to 68% of the fresh water that is now tied up in conventional agriculture. This water could go to thirsty populations. Read more
