I believe Agriculture could be totally adapted to be hydroponic - That water extraction could be developed to extract water from the atmosphere using solar and wind power, that CO2 filter can be built to clean the air (prototype has been made but lack funds to be developed locally) - only the will is lacking to make the world a better place.

We’re retirees and learning to use the computer for personal interests, and mostly through e-mails for contact with friends.

Regular E-mail contact + Hotmail and Skype communication. Regular internet searches fro infor and work research, emails etc. Online training via Centra with Outback Connect and through DECS Centra sessions. Regular mobile phone and text message users. Although little coverage from home, requiring satellite broadband!!!!

Live in the Barossa. I started lessons in the local library, then on an old computer, and will have anew lap-top to continue this year. Used the comptuer for E-mails, writing, playing games, but am still struggling to pick it up as I don’t make enough time to practice. Had a teacher for one course who had been a studen the the school where I used to work as a gardener before my retirement.

The Internet to check share prices and online banking. Plus communications with friend in Australia and overseas.
